Pandas import error: module 'bottleneck' has no attribute '__version__'

Question

I have been using pandas, tensorflow for a few months, but suddenly today I cannot import them. When I try to:

import pandas as pd

It will show:

File "<input>", line 1, in <module>

AttributeError: module 'bottleneck' has no attribute '__version__'

May I know what I can do? I have installed Bottleneck, but seems error still appears.

Answer 1

I got the same problem. I don't really know what it means, but it seems that something must be wrong in the module 'bottleneck'. Then I solved it by :

conda remove bottleneck

conda install bottleneck

Yes, simply reinstall bottleneck, my problem has been solved. Hope this could help you.

Answer 2

I had the same issue, resolved it by upgrading bottleneck then pandas:

pip install --upgrade bottleneck
pip install --upgrade pandas
