Just in case its not anaconda path issue, can you try without anaconda once?

monajalal commented 6 years ago

Why shouldn't work with Anaconda though because Anaconda is pretty much standard nowadays in the community.

/ though my system might have library problems /

pathak22 commented 6 years ago

It should work with anaconda.

Removing anaconda is just to check if system vs. anaconda library paths are not entangled i.e. incorrectly specified.
