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 trial when the experiment is running and the trial's status is FAILED. Perform the following steps:

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

Stop trial

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

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

You can clone an existing experiment to create an identical one. You can also modify the parameters in the cloned experiment to create a new one. You can clone an experiment from the experiment list page in two ways:

• 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 non-running experiment by using one of the following methods:

• 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.
