With ClearML's Reports you can write up notes, experiment findings, or really anything you want. You can create reports in any of your ClearML projects.

In addition to its main document, a report also contains a description field, which will appear in the report's card in the Reports Page. Reports are searchable based on their description, so adding a description can make it easier to find the report later.

Reports are editable Markdown documents, supporting:

  • Multi-level headings
  • Text formatting: Italics, bold, and strikethrough
  • Bulleted and numbered lists
  • Tables
  • Code blocks
  • Text and image hyperlinks
  • Embedded images uploaded from your computer
  • Embedded ClearML task, model, and app content


Publishing a report locks it for future editing, so you can preserve its contents. You can also share your reports, download a PDF copy, or simply copy the MarkDown content and reuse in your editor of choice.

Access ClearML reports through the Reports Page.

Embedding ClearML Visualizations

You can embed plots and images from your ClearML objects (experiments, models, and apps) into your reports: scalar graphs and other plots, and debug samples from an individual object or from an object comparison page. These visualizations are updated live as the object(s) updates.

To add a graphic resource:

  1. Go to the resource you want to embed in your report (a plot or debug sample from an individual object or object comparison)

  2. Hover over the resource and click Generate embed code.

    Reports step 2

    Click Embed in ClearML report. This generates the embed code for accessing the resource, and copies it to your clipboard.

    Reports step 2a

  3. Return to your report page and paste the code snippet

    Reports step 3

Once embedded in the report, you can return to the resource's original location (e.g. comparison page, experiment/model/app page) by clicking Return to resource.

Customizing Embed Code

You can customize embed codes to make more elaborate queries for what you want to display in your reports. A standard embed code is formatted like this:

width="100%" height="400"

The src parameter is made up of the following components:

  • Your web server's URL (e.g.
  • /widget/ - The endpoint that serves the embedded data.
  • The query parameters for your visualization (the path and query are separated by a question mark ?)

The query is formatted like a standard query string: <parameter>=<parameter_value>. Multiple parameter-value pairs are delimited with a &: <parameter_1>=<parameter_value_1>&<parameter_2>=<parameter_value_2>.

The query string usually includes the following parameters:

  • objectType - The type of object to fetch. The options are task or model (task also includes ClearML app instances).
  • objects - Object IDs (i.e. task or model IDs depending on specified ObjectType). Specify multiple IDs like this: objects=<id>&objects=<id>&objects=<id>. Alternatively, you can input a query, and the matching objects' specified resources will be displayed. See Dynamic Queries below.
  • type - The type of resource to fetch. The options are:
    • plot
    • scalar
    • single (single-scalar values table)
    • sample (debug sample)
    • parcoords (hyperparameter comparison plots) - for this option, you need to also specify the following parameters:
      • metrics - Unique metric/variant ID formatted like metric_id.variant_id (see note below)
      • variants - Parameters to include in the plot (write in following format <section_name>.<parameter_1>&<section_name>.<parameter_2>)
      • value_type - Specify which metric values to use. The options are:
        • min_value
        • max_value
        • value (last value)
  • xaxis - Set the x-axis units for plots. The options are:
    • iter - Iteration (default)
    • timestamp - Time from start
    • iso_time - Wall time
  • metrics - Metric name
  • variants - Variant's name
  • company - Workspace ID. Applicable to the ClearML hosted service, for embedding content from a different workspace
  • light - add parameter to switch visualization to light theme
URL encoding

For strings, make sure to use the appropriate URL encoding. For example, if the metric name is "Metric Name", write Metric%20Name

Dynamic Queries

You can create more complex queries by specifying object criteria (e.g. tags, statuses, projects, etc.) instead of specific task IDs, with parameters from the tasks.get_all or models.get_all API calls.

For these parameters, use the following syntax:

  • key=value for non-array fields
  • key[]=<value1>,<value2> for array fields.

Delimit the fields with &s.


The following are examples of dynamic queries. All the examples use objectType=task, but objectType=model can also be used.

  • Request the scalars plot of a specific metric variant for the latest experiment in a project:


    Notice that the project parameter is specified. To get the most recent single experiment, page_size=1&page=0&order_by[]=-last_update is added. page_size specifies how many results are returned in each page, and page specifies which page to return (in this case the first page)--this way you can specify how many experiments you want in your graph. order_by[]=-last_update orders the results by update time in descending order (most recent first).

  • Request the scalars plot of a specific metric variant for the experiments with a specific tag:


    A list of tags that the experiment should contain is specified in the tags argument. You can also specify tags that exclude experiments. See tag filter syntax examples here.

  • Request the training/accuracy scalar plot of the 5 experiments with the best accuracy scores (see Metric/Variant IDs note below):

Metric/Variant IDs

Metric names need to be MD5 encoded for parallel coordinate plots and for ordering query results by metric performance. You can encode the strings in Python with hashlib.md5(str("<metric_string>").encode("utf-8")).hexdigest(), and use the returned MD5 hash in your query.

MarkDown Formatting Quick Guide

The following is a quick reference for the MarkDown syntax that can be used in ClearML Reports.

Heading Levels

To create headings, add # in front of the phrases that you want to turn into headings. The number of # signs correspond to the heading level (i.e. # for level-1 heading, ## for level-2, etc.):

MarkDownRendered Output
# H1
## H2
### H3
#### H4
##### H5
###### H6
Report headings

Text Emphasis

The following table presents the text format options:

Format OptionMarkDownRendered Output
Bold**This is bold text** and __so is this__This is bold text and so is this
Italics*This is italic text* and _so is this_This is italic text and so is this
Inline Code`this is code`this is code


To create a blockquote, add a > before each line of the quote. Nest blockquotes by adding additional > signs before each line of the nested blockquote.

MarkDownRendered Output
> Blockquote
>> Nested quote 1
>>> Nested quote 2
Report Blockquotes


Ordered List

Create an ordered list by numbering the list items with numbers followed by periods. The list items do not have to be numbered correctly, but the list will be rendered numerically starting with 1..

MarkDownRendered Output
1. Item 1
2. Item 2
1. Item 3
1. Item 4
Report ordered list

Unordered List

Create an unordered list by starting each line with the +, -, or * signs. Different signs can be used to create the bullets in the same list, but they are all rendered uniformly.

You can also use checkmarks (* [x]), following any of the bullet signs.

To nest lists, indent nested items 2 spaces more than their parent list item.

MarkDownRendered Output
+ Item 1
+ Item 2
  - Sub-item a:
    * Sub-sub-item x
    + Sub-sub-item y
    - Sub-sub-item z
* [x] A checkmark
Report unordered list


MarkDown code for a table looks like this:

|          | Align Right | Align Left | Align Center |
| -------- | -----------:|:---------- |:------------:|
| 1 | 1 | 1 | 1 |
| 11 | 11 | 11 | 11 |

The rendered output should look like this:

Reports table

Add the table column names in the first row; each name is preceded and followed by a pipe (|). In the second row, add sets of at least three hyphens (---) for each column, and add a pipe before and after each set of hyphens. In the second row, you can specify each table column's contents alignment. To align the contents to the left, place a colon (:) to the left of the hyphens. To align right, place a colon to the right of the hyphens. To center align, place colons on both sides of the hyphens.


To render inline code, surround the code with single backticks (`). For example `code` will be rendered code.

To create block code, use one of the following options:

  • Indent the code

        from clearml import Task

    t = Task.init(project_name='My project', task_name='Base')
  • Surround code with "fences"--three backticks (```):

    from clearml import Task

    t = Task.init(project_name='My project', task_name='Base')

Both of these options will be rendered as:

from clearml import Task

t = Task.init(project_name='My project', task_name='Base')

Syntax Highlighting

To display syntax highlighting, specify the coding language after the first fence (e.g. ```python, ```json, ```js, etc.):

from clearml import Task

t = Task.init(project_name='My project', task_name='Base')

The rendered output should look like this:

from clearml import Task

t = Task.init(project_name='My project', task_name='Base')

To create a link, enclose link text inside brackets, followed by the URL link enclosed in parentheses:

[link text](

The rendered output should look like this: link text

To add a title to the link, which you can see in a tooltip when hovering over the link, add the title after the URL link in the parentheses:

[link with title]( "ClearML Documentation")

The rendered output should look like this: link with title. Hover over the link to see the link's title.

Collapsible Sections

The MarkDown code for a collapsible panel looks like this:

MarkDownRendered Output
 <summary>Section title</summary>
  Collapsible Section Contents
Section title
Collapsible Section Contents

The collapsible panel is surrounded by <details> tags. Within the <details> tag, add the section's title between the <summary> tags. This title can be seen when the panel is collapsed. After the </summary> tag, add the panel contents.

Horizontal Rules

Create horizontal lines using three hyphens (---), underscores (___), or asterisks (***):

Reports horizontal rules


To add an image, add an exclamation point, followed by the alt text enclosed by brackets, followed by the link to the image enclosed in parentheses:


The rendered output should look like this:


To add a title to the image, which you can see in a tooltip when hovering over the image, add the title after the image's link:

![With title]( "ClearML logo")

The rendered output should look like this:

Logo with Title

Hover over the image to see its title.
