Cleaning Up Experiments

Although DVC uses minimal resources to keep track of the experiments, they may clutter tables and the workspace. DVC allows to remove specific experiments from the workspace or delete the ones that are not final yet.

Removing specific experiments

When you want to discard experiments by their name, you can use dvc exp remove and supply the experiment name.

$ dvc exp list
main:
    2399f24 [cnn-128]
    4e8a178 [cnn-32]
    f1edf21 [cnn-64]
$ dvc exp remove cnn-32 cnn-64
Removed experiments: cnn-32,cnn-64

Removing multiple experiments (based on parent commit)

You may wish to remove multiple experiments at once. For example, if you are finished experimenting on the current Git commit and want to discard all experiments derived from it, use dvc exp remove --rev with HEAD.

$ dvc exp list
refs/tags/baseline-experiment:
    2399f24 [cnn-128]
    4e8a178 [cnn-32]
    f1edf21 [cnn-64]
    bdf6fa2 [cnn-96]

$ dvc exp remove --rev HEAD
Removed experiments: cnn-128,cnn-32,cnn-64,cnn-96

Note that dvc exp remove do not delete any objects in the DVC cache. To remove the cache objects, e.g. model files, intermediate artifacts, etc. related with the experiments, you can use dvc gc command.

Removing experiments from remotes

As you push the experiments with dvc exp push, Git remotes may be become cluttered with experiment references. To remove experiments from a Git remote, use dvc exp remove -g.

$ dvc exp remove -g origin unwet-jinn
Removed experiments: unwet-jinn

Removing queued experiments

When you've queued experiments with dvc exp run --queue and later decide not to run them, you can remove them with dvc exp remove --queue.

$ dvc exp run --queue -S param=10
Queued experiment '7b83744' for future execution.
$ dvc exp run --queue -S param=20
Queued experiment '68808d5' for future execution.
$ dvc exp show
