Documentation test in master is passing now.

Documentation test is failing on the PR job, but this seems to be due to some caching behavior me forgetting to merge master.

this seems to be due to some caching behavior.

your pr does not include the final fix PR; it is 3 commits behind master:

matthewdeng/ray@docs-softfail...ray-project:ray:master

you should merge master head and rerun the tests.

[aslonnie]

please merge master head and include the fix required.
