ImportError: cannot import name 'entropy' from 'wafo.stats._distn_infrastructure'

[Cubostar]

After installing wafo on an Anaconda Python 3.7 environment with help from this thread, I tried import wafo and got the titular error. Any fix?

The version I've tried to install is 0.4.0. Here's the full trace, though with the path in the first call omitted:

Hi @Cubostar , I ran into this recently as well. The solution I found was to add the line from scipy.stats import entropy to the import block to the top of the wafo/stats/_distn_infrastructure.py.

It appears that pywafo was relying on the entropy objecting being imported with the glob statement from scipy.stats._distn_infrastructure import *, which no longer appears to work.

This was probably fixed in #54.

Indeed, it should have. Please report back if it hasn't.
