ImportError: cannot import name ellipkm1

Question

I was trying to import scipy.stats, however keep getting the error of 'ImportError: cannot import name ellipkm1'

Here's the complete track record of the error:

Traceback (most recent call last):

ImportError: cannot import name ellipkm1

So what should I do to fix this problem?

Answer 1

I had to upgrade:

pip install scipy --upgrade

to scipy==0.16.1 to make it work. Note that I had uninstalled scipy from root and installed it in a virtualenv.

Also, If you want to use the same version of scipy, you can run:

pip install -U --force-reinstall scipy

I had scipy==0.15.1 and the command above fixed it.
