Task

class Task()​

The Task class is a code template for a Task object which, together with its connected experiment components, represents the current running experiment. These connected components include hyperparameters, loggers, configuration, label enumeration, models, and other artifacts.

The term “main execution Task” refers to the Task context for current running experiment. Python experiment scripts can create one, and only one, main execution Task. It is traceable, and after a script runs and ClearML stores the Task in the ClearML Server (backend), it is modifiable, reproducible, executable by a worker, and you can duplicate it for further experimentation.

The Task class and its methods allow you to create and manage experiments, as well as perform advanced experimentation functions, such as autoML.

danger

Do not construct Task objects directly. Use one of the methods listed below to create experiments or reference existing experiments. Do not define CLEARMLTASK and CLEARMLPROC OS environments, they are used internally for bookkeeping between processes and agents.

For detailed information about creating Task objects, see the following methods:

  • Create a new reproducible Task - Task.init
info

In some cases, Task.init may return a Task object which is already stored in ClearML Server (already initialized), instead of creating a new Task. For a detailed explanation of those cases, see the Task.init method.

  • Manually create a new Task (no auto-logging will apply) - Task.create

  • Get the current running Task - Task.current_task

  • Get another (different) Task - Task.get_task

info

The ClearML documentation often refers to a Task as, “Task (experiment)”.

“Task” refers to the class in the ClearML Python Client Package, the object in your Python experiment script, and the entity with which ClearML Server and ClearML Agent work.

“Experiment” refers to your deep learning solution, including its connected components, inputs, and outputs, and is the experiment you can view, analyze, compare, modify, duplicate, and manage using the ClearML Web-App (UI).

Therefore, a “Task” is effectively an “experiment”, and “Task (experiment)” encompasses its usage throughout the ClearML.

The exception to this Task behavior is sub-tasks (non-reproducible Tasks), which do not use the main execution Task. Creating a sub-task always creates a new Task with a new Task ID.

danger

Do not construct Task manually! Please use Task.init or Task.get_task

Task.add_requirements​

classmethod add_requirements(package_name, package_version=None)

Force the adding of a package to the requirements list. If package_version is None, use the installed package version, if found. Example: Task.add_requirements(‘tensorflow’, ‘2.4.0’) Example: Task.add_requirements(‘tensorflow’, ‘>=2.4’) Example: Task.add_requirements(‘tensorflow’) -> use the installed tensorflow version Example: Task.add_requirements(‘tensorflow’, ‘’) -> no version limit Alternatively, you can add all requirements from a file. Example: Task.add_requirements(‘/path/to/your/project/requirements.txt’)

  • Parameters

    • package_name (str ) – The package name or path to a requirements file to add to the “Installed Packages” section of the task.

    • package_version (Optional[str]) – The package version requirements. If None, then use the installed version.

  • Return type

    None

add_tags​

add_tags(tags)

Add Tags to this task. Old tags are not deleted. When executing a Task (experiment) remotely, this method has no effect.

  • Parameters

    tags (Union[Sequence[str], str]) – A list of tags which describe the Task to add.

  • Return type

    None

artifacts​

property artifacts

A read-only dictionary of Task artifacts (name, artifact).

  • Return type

    Dict[str, Artifact]

  • Returns

    The artifacts.

cache_dir​

property cache_dir

The cache directory which is used to store the Task related files.

  • Return type

    Path

Task.clone​

classmethod clone(source_task=None, name=None, comment=None, parent=None, project=None)

Create a duplicate (a clone) of a Task (experiment). The status of the cloned Task is Draft and modifiable.

Use this method to manage experiments and for autoML.

  • Parameters

    • source_task (str ) – The Task to clone. Specify a Task object or a Task ID. (Optional)

    • name (str ) – The name of the new cloned Task. (Optional)

    • comment (str ) – A comment / description for the new cloned Task. (Optional)

    • parent (str ) – The ID of the parent Task of the new Task.

      • If parent is not specified, then parent is set to source_task.parent.

      • If parent is not specified and source_task.parent is not available, then parent set to source_task.

    • project (str ) – The ID of the project in which to create the new Task. If None, the new task inherits the original Task’s project. (Optional)

  • Returns

    The new cloned Task (experiment).

  • Return type

    Task

close​

close()

Closes the current Task and changes its status to “Completed”. Enables you to manually shut down the task from the process which opened the task.

This method does not terminate the (current) Python process, in contrast to Task.mark_completed.

After having Task.close -d a task, the respective object cannot be used anymore and methods like Task.connect or Task.connect_configuration will throw a ValueError. In order to obtain an object representing the task again, use methods like Task.get_task.

danger

Only call Task.close if you are certain the Task is not needed.

comment​

property comment

Returns the current Task’s (user defined) comments.

  • Return type

    str

completed​

completed(ignore_errors=True)

info

Deprecated, use mark_completed(…) instead

  • Return type

    ()

  • Parameters

    ignore_errors (bool ) –

connect​

connect(mutable, name=None)

Connect an object to a Task object. This connects an experiment component (part of an experiment) to the experiment. For example, an experiment component can be a valid object containing some hyperparameters, or a Model.

  • Parameters

    • mutable (object ) – The experiment component to connect. The object must be one of the following types:

      • argparse - An argparse object for parameters.

      • dict - A dictionary for parameters. Note: only keys of type str are supported.

      • TaskParameters - A TaskParameters object.

      • Model - A model object for initial model warmup, or for model update/snapshot uploading. In practice the model should be either InputModel or OutputModel.

      • type - A Class type, storing all class properties (excluding ‘_’ prefixed properties).

      • object - A class instance, storing all instance properties (excluding ‘_’ prefixed properties).

    • name (str ) – A section name associated with the connected object, if ‘name’ is None defaults to ‘General’ Currently, name is only supported for dict and TaskParameter objects, and should be omitted for the other supported types. (Optional)

      For example, by setting name=’General’ the connected dictionary will be under the General section in the hyperparameters section. While by setting name=’Train’ the connected dictionary will be under the Train section in the hyperparameters section.

  • Return type

    Any

  • Returns

    It will return the same object that was passed as the mutable argument to the method, except if the type of the object is dict. For dicts the Task.connect will return the dict decorated as a ProxyDictPostWrite. This is done to allow propagating the updates from the connected object.

  • Raise

    Raises an exception if passed an unsupported object.

connect_configuration​

connect_configuration(configuration, name=None, description=None)

Connect a configuration dictionary or configuration file (pathlib.Path / str) to a Task object. This method should be called before reading the configuration file.

For example, a local file:

config_file = task.connect_configuration(config_file)
my_params = json.load(open(config_file,'rt'))

A parameter dictionary/list:

my_params = task.connect_configuration(my_params)

  • Parameters

    • configuration (Union[Mapping, list, Path, str]) – The configuration. This is usually the configuration used in the model training process.

      Specify one of the following:

      • A dictionary/list - A dictionary containing the configuration. ClearML stores the configuration in

        the ClearML Server (backend), in a HOCON format (JSON-like format) which is editable.

      • A pathlib2.Path string - A path to the configuration file. ClearML stores the content of the file.

        A local path must be relative path. When executing a Task remotely in a worker, the contents brought from the ClearML Server (backend) overwrites the contents of the file.

    • name (str ) – Configuration section name. default: ‘General’ Allowing users to store multiple configuration dicts/files

    • description (str ) – Configuration section description (text). default: None

  • Return type

    Union[dict, Path, str]

  • Returns

    If a dictionary is specified, then a dictionary is returned. If pathlib2.Path / string is specified, then a path to a local configuration file is returned. Configuration object.

connect_label_enumeration​

connect_label_enumeration(enumeration)

Connect a label enumeration dictionary to a Task (experiment) object.

Later, when creating an output model, the model will include the label enumeration dictionary.

  • Parameters

    enumeration (dict ) – A label enumeration dictionary of string (label) to integer (value) pairs.

    For example:

    {
         "background": 0,
         "person": 1
    }

  • Return type

    Dict[str, int]

  • Returns

    The label enumeration dictionary (JSON).

create_function_task​

create_function_task(func, func_name=None, task_name=None, kwargs)**

Create a new task, and call func with the specified kwargs. One can think of this call as remote forking, where the newly created instance is the new Task calling the specified func with the appropriate kwargs and leaving once the func terminates. Notice that a remote executed function cannot create another child remote executed function.

info

Must be called from the main Task, i.e. the one created by Task.init(…)

The remote Tasks inherits the environment from the creating Task

In the remote Task, the entrypoint is the same as the creating Task

In the remote Task, the execution is the same until reaching this function call

  • Parameters

    • func (Callable) – A function to execute remotely as a single Task. On the remote executed Task the entry-point and the environment are copied from this calling process, only this function call redirect the execution flow to the called func, alongside the passed arguments

    • func_name (Optional[str]) – A unique identifier of the function. Default the function name without the namespace. For example Class.foo() becomes ‘foo’

    • task_name (Optional[str]) – The newly created Task name. Default: the calling Task name + function name

    • kwargs (Optional[Any]) – name specific arguments for the target function. These arguments will appear under the configuration, “Function” section

  • Return type

    Task

Task.debug_simulate_remote_task​

classmethod debug_simulate_remote_task(task_id, reset_task=False)

  • Parameters

    • task_id (str ) – Task ID to simulate, notice that all configuration will be taken from the specified Task, regardless of the code initial values, just like it as if executed by ClearML agent

    • reset_task (bool ) – If True, target Task, is automatically cleared / reset.

  • Return type

    ()

delete​

delete(delete_artifacts_and_models=True, skip_models_used_by_other_tasks=True, raise_on_error=False, callback=None)

Delete the task as well as its output models and artifacts. Models and artifacts are deleted from their storage locations, each using its URI.

The testing script:

# initialize the testing Task
task = Task.init('myProject', 'testing')

# get the training Task
train_task = Task.get_task(project_name='myProject', task_name='training')

# report metrics in the training Task
for x in range(10):
    train_task.get_logger().report_scalar('title', 'series', value=x * 2, iteration=x)

Creates a new Task (experiment) if:

  • The Task never ran before. No Task with the same task_name and project_name is stored in ClearML Server.

  • The Task has run before (the same task_name and project_name), and (a) it stored models and / or artifacts, or (b) its status is Published , or (c) it is Archived.

  • A new Task is forced by calling Task.init with reuse_last_task_id=False.

Otherwise, the already initialized Task object for the same task_name and project_name is returned, or, when being executed remotely on a clearml-agent, the task returned is the existing task from the backend.

info

To reference another Task, instead of initializing the same Task more than once, call Task.get_task. For example, to “share” the same experiment in more than one script, call Task.get_task. See the Task.get_task method for an example.

For example: The first time the following code runs, it will create a new Task. The status will be Completed.

from clearml import Task
task = Task.init('myProject', 'myTask')

If this code runs again, it will not create a new Task. It does not store a model or artifact, it is not Published (its status Completed) , it was not Archived, and a new Task is not forced.

If the Task is Published or Archived, and run again, it will create a new Task with a new Task ID.

The following code will create a new Task every time it runs, because it stores an artifact.

task = Task.init('myProject', 'myOtherTask')

d = {'a': '1'}
task.upload_artifact('myArtifact', d)

  • Parameters

    • project_name (str ) – The name of the project in which the experiment will be created. If the project does not exist, it is created. If project_name is None, the repository name is used. (Optional)

    • task_name (str ) – The name of Task (experiment). If task_name is None, the Python experiment script’s file name is used. (Optional)

    • task_type (TaskTypes ) – The task type. Valid task types:

      • TaskTypes.training (default)

      • TaskTypes.testing

      • TaskTypes.inference

      • TaskTypes.data_processing

      • TaskTypes.application

      • TaskTypes.monitor

      • TaskTypes.controller

      • TaskTypes.optimizer

      • TaskTypes.service

      • TaskTypes.qc

      • TaskTypes.custom

    • tags (Optional[Sequence[str]]) – Add a list of tags (str) to the created Task. For example: tags=[‘512x512’, ‘yolov3’]

    • reuse_last_task_id (bool ) – Force a new Task (experiment) with a previously used Task ID,

      and the same project and Task name. If the previously executed Task has artifacts or models, it will not be reused (overwritten), and a new Task will be created. When a Task is reused, the previous execution outputs are deleted, including console outputs and logs. The values are:

      • True - Reuse the last Task ID. (default)

      • False - Force a new Task (experiment).

      • A string - You can also specify a Task ID (string) to be reused, instead of the cached ID based on the project/name combination.

    • continue_last_task (bool ) – Continue the execution of a previously executed Task (experiment). When

      continuing the executing of a previously executed Task, all previous artifacts / models / logs remain intact. New logs will continue iteration/step based on the previous-execution maximum iteration value. For example, The last train/loss scalar reported was iteration 100, the next report will be iteration 101. The values are:

      • True - Continue the last Task ID. Specified explicitly by reuse_last_task_id or implicitly with the same logic as reuse_last_task_id

      • False - Overwrite the execution of previous Task (default).

      • A string - You can also specify a Task ID (string) to be continued. This is equivalent to continue_last_task=True and reuse_last_task_id=a_task_id_string.

      • An integer - Specify initial iteration offset (override the auto automatic last_iteration_offset). Pass 0, to disable the automatic last_iteration_offset or specify a different initial offset. You can specify a Task ID to be used with reuse_last_task_id=’task_id_here’

    • output_uri (str ) – The default location for output models and other artifacts. If True, the default

      files_server will be used for model storage. In the default location, ClearML creates a subfolder for the output. The subfolder structure is the following: <output destination name> / <project name> / <task name>.<Task ID>. Note that for cloud storage, you must install the ClearML package for your cloud storage type, and then configure your storage credentials. For detailed information, see “Storage” in the ClearML Documentation. The following are examples of output_uri values for the supported locations:

      • A shared folder: /mnt/share/folder

      • S3: s3://bucket/folder

      • Google Cloud Storage: gs://bucket-name/folder

    • auto_connect_arg_parser (Union[bool, Mapping[str, bool]]) – Automatically connect an argparse object to the Task. Supported argument

      parser packages are: argparse, click, python-fire, jsonargparse. The values are:

      • True - Automatically connect. (default)

      • False - Do not automatically connect.

      • A dictionary - In addition to a boolean, you can use a dictionary for fined grained control of connected

        arguments. The dictionary keys are argparse variable names and the values are booleans. The False value excludes the specified argument from the Task’s parameter section. Keys missing from the dictionary default to True, you can change it to be False by adding \* key as False to the dictionary. An empty dictionary defaults to False.

        For example:

        auto_connect_arg_parser={"do_not_include_me": False, }
        auto_connect_arg_parser={"only_include_me": True, "*": False}
        info

        To manually connect an argparse, use Task.connect.

    • auto_connect_frameworks (Union[bool, Mapping[str, Union[bool, str, list]]]) – Automatically connect frameworks This includes patching MatplotLib, XGBoost,

      scikit-learn, Keras callbacks, and TensorBoard/X to serialize plots, graphs, and the model location to the ClearML Server (backend), in addition to original output destination. The values are:

      • True - Automatically connect (default)

      • False - Do not automatically connect

      • A dictionary - In addition to a boolean, you can use a dictionary for fined grained control of connected

        frameworks. The dictionary keys are frameworks and the values are booleans, other dictionaries used for finer control or wildcard strings. In case of wildcard strings, the local path of a model file has to match at least one wildcard to be saved/loaded by ClearML. Example: {‘pytorch’ : ‘.pt’, ‘tensorflow’: [‘.h5’, ‘*’]} Keys missing from the dictionary default to True, and an empty dictionary defaults to False. Supported keys for finer control: {‘tensorboard’: {‘report_hparams’: bool}} # whether to report TensorBoard hyperparameters

        For example:

        auto_connect_frameworks={
            'matplotlib': True, 'tensorflow': ['*.hdf5, 'something_else*], 'tensorboard': True,
            'pytorch': ['*.pt'], 'xgboost': True, 'scikit': True, 'fastai': True,
            'lightgbm': True, 'hydra': True, 'detect_repository': True, 'tfdefines': True,
            'joblib': True, 'megengine': True, 'catboost': True, 'gradio': True
        }
        auto_connect_frameworks={'tensorboard': {'report_hparams': False}}

    • auto_resource_monitoring (bool ) – Automatically create machine resource monitoring plots

      These plots appear in the ClearML Web-App (UI), RESULTS tab, SCALARS sub-tab, with a title of :resource monitor:. The values are:

      • True - Automatically create resource monitoring plots. (default)

      • False - Do not automatically create.

      • Class Type - Create ResourceMonitor object of the specified class type.

    • auto_connect_streams (Union[bool, Mapping[str, bool]]) – Control the automatic logging of stdout and stderr.

      The values are:

      • True - Automatically connect (default)

      • False - Do not automatically connect

      • A dictionary - In addition to a boolean, you can use a dictionary for fined grained control of stdout and

        stderr. The dictionary keys are ‘stdout’ , ‘stderr’ and ‘logging’, the values are booleans. Keys missing from the dictionary default to False, and an empty dictionary defaults to False. Notice, the default behaviour is logging stdout/stderr. The logging module is logged as a by product of the stderr logging

        For example:

        auto_connect_streams={'stdout': True, 'stderr': True, 'logging': False}

    • deferred_init (bool) – (default: False) Wait for Task to be fully initialized (regular behaviour).

      ** BETA feature! use with care **.

      If set to True, Task.init function returns immediately and all initialization / communication to the clearml-server is running in a background thread. The returned object is a full proxy to the regular Task object, hence everything will be working as expected. Default behaviour can be controlled with: CLEARML_DEFERRED_TASK_INIT=1. Notes:

      • Any access to the returned proxy Task object will essentially wait for the Task.init to be completed.

        For example: print(task.name) will wait for Task.init to complete in the background and then return the name property of the task original object

      • Before Task.init completes in the background, auto-magic logging (console/metric) might be missed

      • If running via an agent, this argument is ignored, and Task init is called synchronously (default)

  • Returns

    The main execution Task (Task context)

  • Return type

    Task

input_models_id​

property input_models_id

Returns the current Task’s input model IDs as a dictionary.

  • Return type

    Mapping[str, str]

is_current_task​

is_current_task()

Deprecated: Deprecated since version 0.13.0: This method is deprecated. Use Task.is_main_task instead.

Is this Task object the main execution Task (initially returned by Task.init)

  • Return type

    bool

  • Returns

    Is this Task object the main execution Task

    • True - Is the main execution Task.

    • False - Is not the main execution Task.

is_main_task​

is_main_task()

Is this Task object the main execution Task (initially returned by Task.init)

info

If Task.init was never called, this method will not create it, making this test more efficient than:

Task.init() == task

  • Return type

    bool

  • Returns

    Is this Task object the main execution Task

    • True - Is the main execution Task.

    • False - Is not the main execution Task.

Task.is_offline​

classmethod is_offline()

Return offline-mode state, If in offline-mode, no communication to the backend is enabled.

  • Return type

    bool

  • Returns

    boolean offline-mode state

labels_stats​

property labels_stats

Get accumulated label stats for the current/last frames iteration

  • Return type

    dict

  • Return type

    str

  • Returns

    The worker ID.

launch_multi_node​

launch_multi_node(total_num_nodes, port=29500, queue=None, wait=False, addr=None)

Enqueue multiple clones of the current task to a queue, allowing the task to be ran by multiple workers in parallel. Each task running this way is called a node. Each node has a rank The node that initialized the execution of the other nodes is called the master node and it has a rank equal to 0.

A dictionary named multi_node_instance will be connected to the tasks. One can use this dictionary to modify the behaviour of this function when running remotely. The contents of this dictionary correspond to the parameters of this function, and they are:

  • total_num_nodes - the total number of nodes, including the master node
  • queue - the queue to enqueue the nodes to

The following environment variables, will be set:

  • MASTER_ADDR - the address of the machine that the master node is running on
  • MASTER_PORT - the open port of the machine that the master node is running on
  • WORLD_SIZE - the total number of nodes, including the master
  • RANK - the rank of the current node (master has rank 0)

One may use this function in conjuction with PyTorch’s distributed communication package. Note that Task.launch_multi_node should be called before torch.distributed.init_process_group. For example:

from clearml import Task
import torch
import torch.distributed as dist

def run(rank, size):
    print('World size is ', size)
    tensor = torch.zeros(1)
    if rank == 0:
        for i in range(1, size):
            tensor += 1
            dist.send(tensor=tensor, dst=i)
            print('Sending from rank ', rank, ' to rank ', i, ' data: ', tensor[0])
    else:
        dist.recv(tensor=tensor, src=0)
        print('Rank ', rank, ' received data: ', tensor[0])

if __name__ == '__main__':
    task = Task.init('some_name', 'some_name')
    task.execute_remotely(queue_name='queue')
    config = task.launch_multi_node(4)
    dist.init_process_group('gloo')
    run(config.get('node_rank'), config.get('total_num_nodes'))

When using the ClearML cloud autoscaler apps, one needs to make sure the nodes can reach eachother. The machines need to be in the same security group, the MASTER_PORT needs to be exposed and the MASTER_ADDR needs to be the right private ip of the instance the master is running on. For example, to achieve this, one can set the following Docker arguments in the Additional ClearML Configuration section:

agent.extra_docker_arguments=["--ipc=host", "--network=host", "-p", "29500:29500", "--env", "CLEARML_MULTI_NODE_MASTER_DEF_ADDR=`hostname -I | awk '{print $1}'`"]`

  • Parameters

    • total_num_nodes (int) – The total number of nodes to be enqueued, including the master node, which should already be enqueued when running remotely

    • port (Optional[int]) – Port opened by the master node. If the environment variable CLEARML_MULTI_NODE_MASTER_DEF_PORT is set, the value of this parameter will be set to the one defined in CLEARML_MULTI_NODE_MASTER_DEF_PORT. If CLEARML_MULTI_NODE_MASTER_DEF_PORT doesn’t exist, but MASTER_PORT does, then the value of this parameter will be set to the one defined in MASTER_PORT. If neither environment variables exist, the value passed to the parameter will be used

    • queue (Optional[str]) – The queue to enqueue the nodes to. Can be different from the queue the master node is enqueued to. If None, the nodes will be enqueued to the same queue as the master node

    • wait (bool) – If True, the master node will wait for the other nodes to start

    • addr (Optional[str]) – The address of the master node’s worker. If the environment variable CLEARML_MULTI_NODE_MASTER_DEF_ADDR is set, the value of this parameter will be set to the one defined in CLEARML_MULTI_NODE_MASTER_DEF_ADDR. If CLEARML_MULTI_NODE_MASTER_DEF_ADDR doesn’t exist, but MASTER_ADDR does, then the value of this parameter will be set to the one defined in MASTER_ADDR. If neither environment variables exist, the value passed to the parameter will be used. If this value is None (default), the private IP of the machine the master node is running on will be used.

  • Return type

    dict

  • Returns

    A dictionary containing relevant information regarding the multi node run. This dictionary has the following entries:

    • master_addr - the address of the machine that the master node is running on

    • master_port - the open port of the machine that the master node is running on

    • total_num_nodes - the total number of nodes, including the master

    • queue - the queue the nodes are enqueued to, excluding the master

    • node_rank - the rank of the current node (master has rank 0)

    • wait - if True, the master node will wait for the other nodes to start

logger​

property logger

Get a Logger object for reporting, for this task context. You can view all Logger report output associated with the Task for which this method is called, including metrics, plots, text, tables, and images, in the ClearML Web-App (UI).

  • Return type

    Logger

  • Returns

    The Logger object for the current Task (experiment).

mark_completed​

mark_completed(ignore_errors=True, status_message=None, force=False)

Use this method to close and change status of (remotely!) executed tasks.

This method closes the task it is a member of, changes its status to “Completed”, and terminates the Python process that created the task. This is in contrast to Task.close, which does the first two steps, but does not terminate any Python process.

Let’s say that process A created the task and process B has a handle on the task, e.g., with Task.get_task. Then, if we call Task.mark_completed, process A is terminated, but process B is not.

However, if Task.mark_completed was called from the same process in which the task was created, then - effectively - the process terminates itself. For example, in

task = Task.init(...)
task.mark_completed()
from time import sleep
sleep(30)
print('This text will not be printed!')

the text will not be printed, because the Python process is immediately terminated.

Task.query_tasks​

classmethod query_tasks(project_name=None, task_name=None, tags=None, additional_return_fields=None, task_filter=None)

Get a list of Tasks ID matching the specific query/filter. Notice, if additional_return_fields is specified, returns a list of dictionaries with requested fields (dict per Task)

  • Parameters

    • project_name (str ) – The project name of the Tasks to get. To get the experiment in all projects, use the default value of None. (Optional) Use a list of strings for multiple optional project names.

    • task_name (str ) – The full name or partial name of the Tasks to match within the specified project_name (or all projects if project_name is None). This method supports regular expressions for name matching (if you wish to match special characters and avoid any regex behaviour, use re.escape()). (Optional)

    • project_name – project name (str) the task belongs to (use None for all projects)

    • task_name – task name (str) within the selected project Return any partial match of task_name, regular expressions matching is also supported. If None is passed, returns all tasks within the project

    • tags (list ) – Filter based on the requested list of tags (strings) To exclude a tag add “-” prefix to the tag. Example: [“best”, “-debug”] The default behaviour is to join all tags with a logical “OR” operator. To join all tags with a logical “AND” operator instead, use “$all” as the first string, for example: [“$all”, “best”, “experiment”, “ever”] To join all tags with AND, but exclude a tag use “$not” before the excluded tag, for example: [“$all”, “best”, “experiment”, “ever”, “$not”, “internal”, “$not”, “test”] The “OR” and “AND” operators apply to all tags that follow them until another operator is specified. The NOT operator applies only to the immediately following tag. For example, [“$all”, “a”, “b”, “c”, “$or”, “d”, “$not”, “e”, “$and”, “__$or” “f”, “g”] means (“a” AND “b” AND “c” AND (“d” OR NOT “e”) AND (“f” OR “g”)). See https://clear.ml/docs/latest/docs/clearml_sdk/task_sdk/#tag-filters for more information.

    • additional_return_fields (list ) – Optional, if not provided return a list of Task IDs. If provided return dict per Task with the additional requested fields.

    • config_text (Optional [ str ] ) –

    • config_dict (Optional [ Mapping ] ) –

set_model_label_enumeration​

set_model_label_enumeration(enumeration=None)

Set the label enumeration for the Task object before creating an output model. Later, when creating an output model, the model will inherit these properties.

  • Parameters

    enumeration (dict ) – A label enumeration dictionary of string (label) to integer (value) pairs.

    For example:

    {
         "background": 0,
         "person": 1
    }

Task.set_offline​

classmethod set_offline(offline_mode=False)

Set offline mode, where all data and logs are stored into local folder, for later transmission

info

Task.set_offline can’t move the same task from offline to online, nor can it be applied before Task.create. See below an example of incorrect usage of Task.set_offline:

from clearml import Task

Task.set_offline(True)
task = Task.create(project_name=’DEBUG’, task_name=”offline”)
# ^^^ an error or warning is raised, saying that Task.set_offline(True)
#     is supported only for Task.init
Task.set_offline(False)
# ^^^ an error or warning is raised, saying that running Task.set_offline(False)
#     while the current task is not closed is not supported

data = task.export_task()

imported_task = Task.import_task(task_data=data)

The correct way to use Task.set_offline can be seen in the following example:

from clearml import Task

Task.set_offline(True)
task = Task.init(project_name=’DEBUG’, task_name=”offline”)
task.upload_artifact(“large_artifact”, “test_string”)
task.close()
Task.set_offline(False)

imported_task = Task.import_offline_session(task.get_offline_mode_folder())

Upload (add) a static artifact to a Task object. The artifact is uploaded in the background.

The currently supported upload (static) artifact types include:

  • string / pathlib2.Path - A path to artifact file. If a wildcard or a folder is specified, then ClearML creates and uploads a ZIP file.

  • dict - ClearML stores a dictionary as .json (or see extension_name) file and uploads it.

  • pandas.DataFrame - ClearML stores a pandas.DataFrame as .csv.gz (compressed CSV) (or see extension_name) file and uploads it.

  • numpy.ndarray - ClearML stores a numpy.ndarray as .npz (or see extension_name) file and uploads it.

  • PIL.Image - ClearML stores a PIL.Image as .png (or see extension_name) file and uploads it.

  • Any - If called with auto_pickle=True, the object will be pickled and uploaded.

  • Parameters

    • name (str ) – The artifact name.

      danger

      If an artifact with the same name was previously uploaded, then it is overwritten.

    • artifact_object (object ) – The artifact object.

    • metadata (dict ) – A dictionary of key-value pairs for any metadata. This dictionary appears with the experiment in the ClearML Web-App (UI), ARTIFACTS tab.

    • delete_after_upload (bool ) – After the upload, delete the local copy of the artifact

      • True - Delete the local copy of the artifact.

      • False - Do not delete. (default)

    • auto_pickle (bool ) – If True (default) and the artifact_object is not one of the following types: pathlib2.Path, dict, pandas.DataFrame, numpy.ndarray, PIL.Image, url (string), local_file (string), the artifact_object will be pickled and uploaded as pickle file artifact (with file extension .pkl)

    • preview (Any ) – The artifact preview

    • wait_on_upload (bool ) – Whether the upload should be synchronous, forcing the upload to complete before continuing.

    • extension_name (str ) – File extension which indicates the format the artifact should be stored as.

      The following are supported, depending on the artifact type (default value applies when extension_name is None):

      • Any - .pkl if passed supersedes any other serialization type, and always pickles the object

      • dict - .json, .yaml (default .json)

      • pandas.DataFrame - .csv.gz, .parquet, .feather, .pickle (default .csv.gz)

      • numpy.ndarray - .npz, .csv.gz (default .npz)

      • PIL.Image - whatever extensions PIL supports (default .png)

      • In case the serialization_function argument is set - any extension is supported

    • Union [ bytes , bytearray ] ] serialization_function (Callable [ Any , ) – A serialization function that takes one parameter of any type which is the object to be serialized. The function should return a bytes or bytearray object, which represents the serialized object. Note that the object will be immediately serialized using this function, thus other serialization methods will not be used (e.g. pandas.DataFrame.to_csv), even if possible. To deserialize this artifact when getting it using the Artifact.get method, use its deserialization_function argument.

    • retries (int ) – Number of retries before failing to upload artifact. If 0, the upload is not retried

    • serialization_function (Optional [ Callable [ [ Any ] , Union [ bytes , bytearray ] ] ] ) –

  • Return type
