PyTorch Model Updating

The example demonstrates training a model and logging it using the OutputModel class.

The example does the following:

  • Creates a task named Model update pytorch in the examples project.
  • Trains a neural network on the CIFAR10 dataset for image classification.
  • Uses an OutputModel object to log the model, its label enumeration and configuration dictionary.
Disabling automatic framework logging

This example disables the default automatic capturing of PyTorch outputs, to demonstrate how to manually control what is logged from PyTorch. See this FAQ for more information.


An OutputModel object is instantiated for the task.

from clearml import Task, OutputModel

task = Task.init(
task_name="Model update pytorch",
auto_connect_frameworks={"pytorch": False}

output_model = OutputModel(task=task)

Label Enumeration

The label enumeration dictionary is logged using the Task.connect_label_enumeration method which will update the task’s resulting model information. The current running task is accessed using the Task.current_task class method.

# store the label enumeration of the training model
classes = ("plane", "car", "bird", "cat", "deer", "dog", "frog", "horse", "ship", "truck",)
enumeration = {k: v for v, k in enumerate(classes, 1)}
Directly Setting Model Enumeration

You can set a model’s label enumeration directly using the OutputModel.update_labels method

Model Configuration

Add a configuration dictionary to the model using the OutputModel.update_design method.

model_config_dict = {
"list_of_ints": [1, 2, 3, 4],
"dict": {
"sub_value": "string",
"sub_integer": 11
"value": 13.37


Updating Models

To update a model, use the OutputModel.update_weights method. This uploads the model to the set storage destination (see Setting Upload Destination), and registers that location to the task as the output model.

# CONDITION depicts a custom condition for when to save the model. The model is saved and then updated in ClearML



The model appears in the task’s ARTIFACTS tab.

Clicking on the model name takes you to the model’s page, where you can view the model’s details and access the model.
