title: Tracking Experiments and Visualizing Results
|
|
---
|
|
|
|
While an experiment is running, and any time after it finishes, track it and visualize the results in the ClearML Web UI,
|
|
including:
|
|
|
|
* [Execution details](#execution) - Code, the base Docker image used for [ClearML Agent](../clearml_agent.md), output destination for artifacts, and the logging level.
|
|
* [Configuration](#configuration) - Hyperparameters, user properties, and configuration objects.
|
|
* [Artifacts](#artifacts) - Input model, output model, model snapshot locations, other artifacts.
|
|
* [General information](#general-information) - Information about the experiment, for example: the experiment start, create, and last update times and dates, user creating the experiment, and its description.
|
|
* [Console](#console) - stdout, stderr, output to the console from libraries, and ClearML explicit reporting.
|
|
* [Scalars](#scalars) - Metric plots.
|
|
* [Plots](#plots) - Other plots and data, for example: Matplotlib, Plotly, and ClearML explicit reporting.
|
|
* [Debug samples](#debug-samples) - Images, audio, video, and HTML.
|
|
|
|
## Viewing Modes
|
|
|
|
The ClearML Web UI provides two viewing modes for experiment details:
|
|
|
|
* The info panel
|
|
|
|
* Full screen details mode.
|
|
|
|
Both modes contain all experiment details. When either view is open, switch to the other mode by clicking <img src="/docs/latest/icons/ico-info-min.svg" alt="Table/Full screen view" className="icon size-md space-sm" />
|
|
(**View in experiments table / full screen**), or clicking <img src="/docs/latest/icons/ico-bars-menu.svg" alt="Bars menu" className="icon size-sm space-sm" /> (**menu**) > **View in experiments
|
|
table / full screen**.
|
|
|
|
|
|
### Info Panel
|
|
|
|
The info panel keeps the experiment table in view so that [experiment actions](webapp_exp_table.md#experiment-actions)
|
|
can be performed from the table (as well as the menu in the info panel).
|
|
|
|
|
|
|
|
Click <img src="/docs/latest/icons/ico-compact-view.svg" alt="Compressed view" className="icon size-md space-sm" /> to
|
|
hide details in the experiment table, so only the experiment names and statuses are displayed
|
|
|
|
|
|
|
|
### Full Screen Details View
|
|
|
|
The full screen details view allows for easier viewing and working with experiment tracking and results. The experiments
|
|
table is not visible when the full screen details view is open. Perform experiment actions from the menu.
|
|
|
|
|
|
|
|
|
|
## Execution
|
|
An experiment's **EXECUTION** tab of lists the following:
|
|
* Source code
|
|
* Uncommitted changes
|
|
* Installed Python packages
|
|
* Container details
|
|
* Output details
|
|
|
|
In full-screen mode, the source code and output details are grouped in the **DETAILS** section.
|
|
|
|
### Source Code
|
|
|
|
The Source Code section of an experiment's **EXECUTION** tab includes:
|
|
* The experiment's repository
|
|
* Commit ID
|
|
* Script path
|
|
* Working directory
|
|
* Binary (Python executable)
|
|
|
|
|
|
|
|
### Uncommitted Changes
|
|
|
|
ClearML displays the git diff of the experiment in the Uncommitted Changes section.
|
|
|
|
|
|
|
|
### Installed Packages
|
|
|
|
The Installed Packages section lists the experiment's installed Python packages and their versions.
|
|
|
|
|
|
|
|
When a ClearML agent executing an experiment ends up using a different set of python packages than was originally
|
|
specified, both the original specification (`original pip` or `original conda`), and the packages the agent ended up
|
|
using to set up an environment (`pip` or `conda`) are available. Select which requirements to view in the dropdown menu.
|
|
|
|
|
|
|
|
### Container
|
|
The Container section list the following information:
|
|
* Image - a pre-configured Docker that ClearML Agent will use to remotely execute this experiment (see [Building Docker containers](../clearml_agent.md#exporting-a-task-into-a-standalone-docker-container))
|
|
* Arguments - add Docker arguments
|
|
* Setup shell script - a bash script to be executed inside the Docker before setting up the experiment's environment
|
|
|
|
|
|
|
|
|
|
### Output
|
|
The Output details include:
|
|
* The output destination used for storing model checkpoints (snapshots) and artifacts (see also, [default_output_uri](../configs/clearml_conf.md#config_default_output_uri)
|
|
in the configuration file, and `output_uri` in [`Task.init`](../references/sdk/task.md#taskinit) parameters).
|
|
|
|
|
|
|
|
## Configuration
|
|
|
|
All parameters and configuration objects appear in the **CONFIGURATION** tab.
|
|
|
|
|
|
### Hyperparameters
|
|
|
|
Hyperparameters are grouped by their type and appear in **CONFIGURATION** **>** **HYPERPARAMETERS**. Once an experiment
|
|
is run and stored in ClearML Server, any of these hyperparameters can be [modified](webapp_exp_tuning.md#modifying-experiments).
|
|
|
|
#### Command Line Arguments
|
|
|
|
The **Args** group shows automatically logged argument parser parameters (e.g. `argparse`, `click`, `hydra`).
|
|
Hover over <img src="/docs/latest/icons/ico-description.svg" alt="Description" className="icon size-md space-sm" /> (menu) on a
|
|
parameter's line, and the type, description, and default value appear, if they were provided.
|
|
|
|
|
|
|
|
#### Environment Variables
|
|
|
|
If the `CLEARML_LOG_ENVIRONMENT` variable was set, the **Environment** group will show environment variables (see [this FAQ](../faq.md#track-env-vars)).
|
|
|
|
|
|
|
|
#### Custom Parameter Groups
|
|
|
|
Custom parameter groups show parameter dictionaries if the parameters were connected to the Task, using
|
|
[`Task.connect()`](../references/sdk/task.md#connect) with a `name` argument provided. `General` is the default section
|
|
if a name is not provided.
|
|
|
|
|
|
|
|
#### TensorFlow Definitions
|
|
|
|
The **TF_DEFINE** parameter group shows automatic TensorFlow logging.
|
|
|
|
|
|
|
|
### User Properties
|
|
|
|
User properties allow to store any descriptive information in a key-value pair format. They are editable in any experiment,
|
|
except experiments whose status is *Published* (read-only).
|
|
|
|
|
|
|
|
### Configuration Objects
|
|
|
|
ClearML tracks experiment (Task) model configuration objects, which appear in **Configuration Objects** **>** **General**.
|
|
These objects include those that are automatically tracked, and those connected to a Task in code (see [`Task.connect_configuration`](../references/sdk/task.md#connect_configuration)).
|
|
|
|
|
|
|
|
ClearML supports providing a name for a Task model configuration object (see the `name`
|
|
parameter in [`Task.connect_configuration`](../references/sdk/task.md#connect_configuration)).
|
|
|
|
|
|
|
|
|
|
## Artifacts
|
|
|
|
Artifacts tracked in an experiment appear in the **ARTIFACTS** tab, and include models and other artifacts.
|
|
|
|
Artifacts location is stored in the `FILE PATH` field.
|
|
The UI provides locally stored artifacts with a 'copy to clipboard' action (<img src="/docs/latest/icons/ico-clipboard.svg" alt="Clipboard" className="icon size-sm space-sm" />)
|
|
to facilitate local storage access (since web applications are prohibited from accessing the local disk for security reasons).
|
|
The UI provides Network hosted (e.g. https://, s3:// etc. URIs) artifacts with a download action (<img src="/docs/latest/icons/ico-download-json.svg" alt="Download" className="icon size-sm space-sm" />)
|
|
to retrieve these files.
|
|
|
|
### Models
|
|
|
|
The input and output models appear in the **ARTIFACTS** tab. Models are associated with the experiment, but to see further model details,
|
|
including design, label enumeration, and general information, go to the **MODELS** tab, by clicking the model name, which is a hyperlink to those details.
|
|
|
|
**To retrieve a model:**
|
|
|
|
1. In the **ARTIFACTS** tab **>** **MODELS** **>** **Input Model** or **Output Model**, click the model name hyperlink.
|
|
1. In the model details **>** **GENERAL** tab **>** **MODEL URL**, either:
|
|
|
|
* Download the model<img src="/docs/latest/icons/ico-download.svg" className="icon size-md space-sm" />, if it is stored in remote storage.
|
|
* Copy its location to the clipboard <img src="/docs/latest/icons/ico-clipboard.svg" alt="Copy Clipboard" className="icon size-md space-sm" />,
|
|
if it is in a local file.
|
|
|
|
|
|
|
|
|
|
### Other Artifacts
|
|
|
|
Other artifacts, which are uploaded but not dynamically tracked after the upload, appear in the **OTHER** section.
|
|
They include the file path, file size, and hash.
|
|
|
|
**To retrieve Other artifacts:**
|
|
|
|
In the **ARTIFACTS** tab **>** **OTHER** **>** Select an artifact **>** Either:
|
|
* Download the artifact <img src="/docs/latest/icons/ico-download.svg" className="icon size-md space-sm" />, if it is stored in remote storage.

:::tip Embedding ClearML Visualization
|
|
You can embed experiment plots and debug samples into ClearML [Reports](webapp_reports.md). These visualizations are
|
|
updated live as the experiment(s) updates. The Enterprise Plan and Hosted Service support embedding resources in external
|
|
tools (e.g. Notion). See [Plot Controls](#plot-controls).
|
|
:::
|
|

### Scalars
|
|
|
|
All scalars that ClearML automatically logs, as well as those explicitly reported in code, appear in
|
|
**SCALARS**.
|
|
|
|
Scalar series are presented in a line chart. To see the series for a metric in high resolution,
|
|
view it in full screen mode by hovering over the graph and clicking <img src="/docs/latest/icons/ico-maximize.svg" alt="Maximize plot icon" className="icon size-sm space-sm" />.

Scalar graphs in full screen mode do not auto-refresh. Click <img src="/docs/latest/icons/ico-reset.svg" alt="Refresh" className="icon lt size-md space-sm medium-zoom-image" />
|
|
to update the graph.
|
|
:::
|
|
|
|
Reported single value scalars are aggregated into a table plot displaying scalar names and values (see [`Logger.report_single_value`](../references/sdk/logger.md#report_single_value)).
|
|
|
|
|
|
#### Scalar Plot Tools

|
|
which will copy to clipboard the embed code to put in your Reports. In contrast to static screenshots, embedded resources
|
|
are retrieved when the report is displayed allowing your reports to show the latest up-to-date data.
|
|
|
|
See additional [plot controls](#plot-controls) below.
|
|
|
|
### Plots
|
|
Non-time-series plots appear in **PLOTS**. These include data generated by libraries, visualization tools, and
|
|
explicitly reported using the ClearML Logger. These may include 2D and 3D plots, tables (Pandas and CSV files), and
|
|
Plotly plots. Individual plots can be shown / hidden or filtered by title.
|
|
|
|
|
|
|
|
For each metric, the latest reported plot is displayed.
|
|
|
|
When viewing a plot in full screen (<img src="/docs/latest/icons/ico-maximize.svg" alt="Maximize plot icon" className="icon size-sm space-sm" />),
|
|
older iterations are available through the iteration slider (or using the up/down arrow keyboard shortcut). Go to the
|
|
previous/next plot in the current iteration using the <img src="/docs/latest/icons/ico-previous.svg" alt="Previous" className="icon size-sm space-sm" /> / <img src="/docs/latest/icons/ico-next.svg" alt="Next" className="icon size-sm space-sm" />

### Debug Samples
|
|
|
|
Experiment outputs such as images, audio, and videos appear in **DEBUG SAMPLES**. These include data generated by
|
|
libraries and visualization tools, and explicitly reported using the [ClearML Logger](../fundamentals/logger.md).
|
|
|
|
You can view debug samples by metric in the reported iterations. Filter the samples by metric by selecting a metric from the
|
|
dropdown menu above the samples. The most recent iteration appears first.
|
|
|
|
|
|
|
|
For each metric, the latest reported debug sample is displayed.

|
|
|
|
Tags are user-defined, color-coded labels that can be added to experiments (and pipelines, datasets, and models),
|
|
allowing to easily identify and group experiments. Tags can help in organizing, querying, and automating experiments.
|
|
For example, tag experiments by the machine type used to execute them, label versions, team names, or any other
|
|
category.
|
|
|
|
You can use tags to filter your experiments in your experiment table (see [Filtering Columns](webapp_exp_table.md#filtering-columns))
|
|
or when querying experiments in your code (see [Tag Filters](../clearml_sdk/task_sdk.md#tag-filters)). You can trigger
