Realized I wasn't running python but ipython, probably with an old version.
conda install ipython solved this problem for me.

I did a conda update pandas at the anaconda prompt today to update from 0.23.x to 0.25.3 and now I get this error in Spyder importing pandas.
pandas\compat\_optional.py", line 48, in _get_version raise ImportError("Can't determine version for {}".format(module.__name__))
ImportError: Can't determine version for bottleneck

I had the same message but found installing it [conda|pip] install Bottleneck fixed it

[kknjio]

I solved it using conda install --all.
