Depending on what you are doing simpley changing the import statement in
python3.8/site-packages/pandas_datareader/compat/__init__.py
from
from pandas.util.testing import assert_frame_equal
to
from pandas.testing import assert_frame_equal

My PR implementing @zackproject suggestion didn't pass the CI checks. I don't have time to further review but I hope someone can resolve the PR checks and get this patch implemented.

I know this has been closed in Apr. 23rd, but the warning still persists.
Just stopped the warning following @zackproject advice.
For the Anaconda users I suggest to look for the pandas_datareader fodler in the sitepackage of the used env.
