I have started learning Tensorflow. I am using Pycharm and my environment is Ubuntu 16.04. I am following the tutorial. I cross check the nump. It is up-to-date. I don't know the reason of this error.
from numpy.lib.arraypad import _validate_lengths
ImportError: cannot import name '_validate_lengths'
Need hint to resolve this error. Thank you.

I updated my skimage package.
pip install --upgrade scikit-image
And the problem was solved. It's a problem of version of Skimage, which is solved in 0.14.2. PLus, this version is quite stable.
