Download an artifact from W&B by its path.The PATH format is entity/project/artifact_name:version. If
the version is omitted, use the “latest” alias.For example, to download the latest version of an artifact called “processed-training-set”
from the “foobar” project under the “team-awesome” entity:
wandb artifact get team-awesome/foobar/processed-training-set:latest
To download a specific version (v2) of the “processed-training-set” artifact
to a local directory (./data):
wandb artifact get --root ./data team-awesome/foobar/processed-training-set:v2
