exp pull

Download an experiment from a Git remote, and its data from a dvc remote.

Synopsis

usage: dvc exp pull [-h] [-q | -v] [-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 pull

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 an experiment name or hash (see dvc exp run) to pull.

The first action of dvc exp pull is to download the experiment so it's available in the local repository (equivalent to git fetch <git_remote> refs/exps/<experiment>). Use dvc exp show to explore your local experiments.

By default, this command will also try to pull all cached data associated with the experiment to DVC remote storage, unless --no-cache is used.

💡 Note that git push <git_remote> --delete <experiment> can be used to delete a pushed experiment.

Options

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

• --no-cache - do not pull cached files files associated with this experiment from DVC remote storage.

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

• --run-cache - downloads all available history of stage runs from the dvc remote (to the cache only, like dvc fetch --run-cache). Note that dvc exp run <stage_name> is necessary to checkout these files.

• -j <number>, --jobs <number> - parallelism level for DVC to upload data to remote storage. The default value is 4 * cpu_count(). For SSH remotes, the default is 4. 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 cloned a DVC repository, and would like to fetch an experiment that someone else shared (see also dvc exp list).

$ dvc exp list --all origin
master:
        exp-e6c97
$ dvc exp pull origin exp-e6c97
Pulled experiment 'exp-e6c97' from Git remote 'origin'.

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

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