How to use the command 'dvc unfreeze' (with examples)

The ‘dvc unfreeze’ command is used to unfreeze stages in the DVC (Data Version Control) pipeline. When a stage is frozen using the ‘dvc freeze’ command, DVC stops tracking changes in its dependencies. However, if you want to start tracking changes in stage dependencies again, you can use the ‘dvc unfreeze’ command.

Use case 1: Unfreeze 1 or more specified stages

Code:

dvc unfreeze stage_name_a [stage_name_b ...]

Motivation: In a DVC pipeline, you may have certain stages that you want to unfreeze so that DVC can start tracking changes in their dependencies again. This can be useful when you need to modify a stage or its dependencies and want DVC to reflect those changes.

Explanation:

• stage_name_a [stage_name_b ...]: The stage names that you want to unfreeze. You can specify one or more stage names separated by a space.

Example output:

Unfreezing stage 'stage1'...
Unfreezing stage 'stage2'...

In this example, the command dvc unfreeze stage1 stage2 is used to unfreeze the ‘stage1’ and ‘stage2’ stages in the DVC pipeline. The output confirms that the stages ‘stage1’ and ‘stage2’ have been unfrozen.
