exp push

Upload experiments to a Git remote, and their data to a dvc remote.

Synopsis

usage: dvc exp push [-h] [-q | -v] [-A] [--rev <commit>] [-n <num>] [-f]
                    [--no-cache] [-r <name>] [-j <number>] [--run-cache]
                    git_remote [experiment ...]

positional arguments:
  git_remote          Git remote name or Git URL
  experiment          Experiment to push

Description

The dvc exp push and dvc exp pull commands are the means for sharing experiments across repository copies via Git and DVC remotes.

Plain git push and git fetch don't work with experiments because these are saved under custom Git references. See How does DVC track experiments? in dvc exp run to learn more about DVC experiment storage.

A working git_remote name (e.g. origin) or Git URL is required, as well as one or more experiment names or hashes (see dvc exp run) to push.

The first action of dvc exp push is to upload the experiments to the Git remote so they can be pulled later from other repo clones (equivalent to git push <git_remote> refs/exps/<experiment>). Use dvc exp list <git_remote> to see experiments in the remote.

This command will also try to push all cached data associated with the experiments to DVC remote storage, unless --no-cache is used.

Options

  • -A, --all-commits - push all experiments in the repository (overrides --rev and --num).

  • --rev <commit> - push experiments derived from the specified <commit> as baseline.

  • -n <num>, --num <num> - push experiments from the last num commits (first parents) starting from the --rev baseline. Give a negative value to include all first-parent commits (similar to git log -n).

  • -f, --force - rewrite the experiment commit if it already exists in the Git remote. Equivalent to git push --force (rewrites history)

  • --no-cache - do not push cached files associated with this experiment to a DVC remote.

  • -r <name>, --remote <name> - name of the dvc remote to push cached files to.

  • --run-cache - uploads all available history of stage runs to the dvc remote.

  • -j <number>, --jobs <number> - parallelism level for DVC to upload data to remote storage. The default value is 4 * cpu_count(). Note that the default value can be set using the jobs config option with dvc remote modify. Using more jobs may improve the overall transfer speed.

  • -h, --help - shows the help message and exit.

  • -q, --quiet - do not write anything to standard output. Exit with 0 if no problems arise, otherwise 1.

  • -v, --verbose - displays detailed tracing information from executing the dvc pull command.

Examples

This example is based on our Get Started, where you can find the actual source code.

Let's say we have run 3 experiments in our project:

$ dvc exp list --all-commits
11-bigrams-experiment:
        exp-e6c97
        exp-1dad0
        exp-1df77

We would now like to share one of them with others via the Git remote:

$ dvc exp push origin exp-e6c97
Pushed experiment 'exp-e6c97' to Git remote 'origin'.

We can now see that the experiment exists in the remote repo:

$ dvc exp list --all origin
master:
        exp-e6c97
