I've update to pandas version v0.15.1 via anaconda (cmd -> conda update pandas) - using python 3.4. Now when I try to import pandas the following error appears "ImportError: cannot import name 'hashtable' ". Anyone an idea how to solve the error? Thank you.

  • I have tried to follow what has been suggested but I cannot solve my issue. I installed cython as someone suggested but still nothing and it has been working all the time without any issues. I simply updated pandas and then the issue was there. – MMCM_ Dec 06 '14 at 16:29
  • Have you tried downgrading back to your previous `pandas` version and see if the problem persists? The answer in the linked question suggests that you should not encounter this problem if you are in a `conda` environment. Did you make sure that the interpreter you are using is indeed from your conda virtualenv? – cel Dec 06 '14 at 16:35
  • I have just downgraded to v0.14.1 and works again. However, I upgraded because I need something from v0.15.1 – MMCM_ Dec 06 '14 at 16:46
  • that is indeed interesting. I am currently using `0.15.1` on python3.3 on OSX and I don't see any issues. You may want to post a bug report at `conda`'s bugtracker at github and include your `OS` and python version. – cel Dec 06 '14 at 16:51

Close Spyder and other Python processes and try

conda install -f pandas
