Have get look in local cache like import does

[davesteps]

If I run dvc import . --rev v0.1.0 model.h5 dvc knows to look for the file in the local cache. If I run the same using get it does not look for the file in the local cache but downloads from the remote every time. I don't know if there is a particular reason get couldn't use the local cache?

The reason for wanting to do this relates to using a previous version of a model as initial weights. Please see this question for more context:

Sorry for responding late, @davesteps.

dvc import/get are mainly used for getting artifacts from remote. import only deals with the DVC repo, whereas get is more general, on that it supports downloading files from git repos too, and can be used without being inside a DVC repo. So, due to this, get has to work without any cache.

But, we are working on this, and this issue is similar to dvc list not working for local repo (in that it clones), see: #4604. /cc @efiop
