Manage your experiments and trials by cloning, editing, stopping, or deleting them as needed.

Edit experiment

While an experiment is running, you can edit its parameters to find the optimal hyperparameter combination faster or discover a better one.

  1. Go to the AutoML page.

    1. Log on to the PAI console.

    2. In the left-side navigation pane, click Workspaces. On the Workspaces page, click the name of the workspace that you want to manage.

    3. In the left-side navigation pane, choose Model Training > AutoML.

  2. You can edit the experiment in one of the following ways:

    • Method 1: While the experiment is running, click Edit in the Actions column of the target experiment. On the Update Experiment page, modify the parameters and click Submit.

    • Method 2: Click the experiment name to go to the Experiment Details page. While the experiment is running, click the Edit button in the upper-right corner of the page. On the Update Experiment page, modify the parameters and click Submit.

Rerun trial

You can rerun a failed trial while the experiment is still running.

Note

Rerunning a trial creates a new trial. This starts a DLC or MaxCompute job and consumes cloud computing resources.

  1. On the Experiments page, click the name of the target experiment to go to the Experiment Details page.

  2. On the Trials tab, find the trial with a FAILED status and click Rerun in its Actions column.

  3. In the confirmation dialog box, click Determine.

Stop experiment

To conserve resources, you can manually stop a running experiment. On the Experiments page, click Stop in the Actions column of a running experiment. The system stops all running trials within the experiment first, then stops the experiment itself.

Stop trial

To conserve resources, you can manually stop a running trial. Stopping a single trial does not affect the overall experiment status.

  1. On the Experiments page, click the name of the target experiment to go to the Experiment Details page.

  2. On the Trials tab, find a running trial and click Stop in its Actions column.

Clone experiment

Clone an existing experiment to create an identical copy. You can also modify the parameters in the cloned experiment to create a new one.

  • Method 1: Click Clone in the Actions column of the target experiment. On the Create Experiment page, confirm the parameters and click Submit.

  • Method 2: Click the experiment name to go to the Experiment Details page. Click the Clone button in the upper-right corner of the page. On the Create Experiment page, confirm the parameters and click Submit.

Delete experiment

You can delete any experiment that is not currently running.

Important

After an experiment is deleted, its information is permanently lost and cannot be recovered.

  • Method 1: On the Experiments page, click Delete in the Actions column of the target experiment. In the Tips dialog box that appears, click Determine.

  • Method 2: On the Experiments page, click the name of the target experiment to go to the Experiment Details page. In the upper-right corner of the page, click the Delete button. In the Tips dialog box, click Determine.
