set cache not working if never cached

[aaronspring]

After upgrading to the new 0.7 climetlab, set("cache-directory", path) does not work anymore. EDIT: maybe this has nothing to do with the new climetlab, but rather if nothing has been cached yet. At least when nothing has been cached in the past.

Is that on purpose or if not, could you please add a small note to the documentation? https://climetlab.readthedocs.io/en/latest/reference/settings.html

import climetlab
# no caching before ever
cml.settings.set("cache-directory", ".")
