Reproducing Experiments

Reproduce experiments on local or remote machines in one of the following ways:

  • Cloning any experiment - Make an exact copy, while maintaining the original experiment
  • Resetting an experiment whose status is not Published - Delete the previous run's logs and output

After cloning or resetting, enqueue the reset or newly cloned experiment for execution by a worker.

Experiments can also be modified and then executed remotely, see Tuning Experiments.


To clone an experiment:

  1. In the experiments table, right-click the experiment to reproduce and click Clone.
  2. In the Clone Experiment modal, set the following:
    • Project - The project where the experiment will be saved
    • Description (optional)
    • Set <cloned_experiment> as parent - Select to set this experiment as the new experiments' parent task
  3. Click Clone

By default, the new experiment’s parent task is set to the original task’s parent, unless the original task does not have a parent, in which case the original task is set as the parent. Select Set <cloned_experiment> as parent to force the original experiment to become the clone’s parent.

To reset an experiment:

  1. In the experiments table, right-click the relevant experiment and click Reset.
  2. In the Reset Experiment modal, if you want the experiment's artifacts and debug samples to be deleted from the ClearML file server, click the checkbox
  3. Click Reset

Final Steps

At the end of the process you are left with an experiment with draft status, meaning that it is editable.

Re-execute the new experiment:

  1. If desired, modify the experiment’s configuration (see Tuning Experiments).

  2. Enqueue the experiment for execution. Right-click the experiment > Enqueue > Select a queue > ENQUEUE.


    Make sure that a ClearML Agent has been assigned to the selected queue

A ClearML Agent will fetch the experiment from the queue and execute it. The experiment can now be tracked and its results visualized.
