dvc checkout (with examples)
1: Checkout the latest version of all target files and directories
dvc checkout
Motivation:
The motivation behind using this command is to retrieve the latest version of all target files and directories from the DVC cache. This can be useful when switching between different branches or when working with collaborators who have made changes to the data.
Explanation:
The dvc checkout command is used to checkout data files and directories from the DVC cache. When executed without any arguments, it retrieves the latest version of all target files and directories.
Example Output:
Checking out '{target1}': 100%|█████████████████| 10/10 [00:01<00:00, 5.56it/s]
Checking out '{target2}': 100%|█████████████████| 20/20 [00:02<00:00, 9.52it/s]
2: Checkout the latest version of a specified target
dvc checkout target
Motivation:
Sometimes it is necessary to only retrieve the latest version of a specific target file or directory from the DVC cache. This can be useful when working with large datasets where we only need to access a subset of the data.
Explanation:
The dvc checkout command can be used with a target argument to specify a particular file or directory to be checked out from the DVC cache. It retrieves the latest version of the specified target.
Example Output:
Checking out '{target}': 100%|█████████████████| 10/10 [00:01<00:00, 5.56it/s]
3: Checkout a specific version of a target from a different Git commit/tag/branch
git checkout commit_hash|tag|branch target && dvc checkout target
Motivation:
There might be cases when we want to retrieve a specific version of a target file or directory from the DVC cache that is associated with a different Git commit, tag, or branch. This can be useful when comparing results between different versions of the code or when reverting to a previous state of the code.
Explanation:
To checkout a specific version of a target file or directory from a different Git commit, tag, or branch, we first use the git checkout command with the desired commit hash, tag, or branch. After that, we use the dvc checkout command to retrieve the specific version of the target from the DVC cache.
Example Output:
Switched to branch 'branch_name'
Checking out '{target}': 100%|█████████████████| 10/10 [00:01<00:00, 5.56it/s]
