I am sorry. It seems that there is some confusion.
The following lines, can be commented or not. It does not change anything
from mpl_toolkits.mplot3d import Axes3D
import mpl_toolkits.mplot3d.axes3d as axes3d)
I do not use pip. However pip list provides a list of 207 pacakges.
The error is the same in python2 and python3
ax.yaxis.set_scale('log')
AttributeError: 'YAxis' object has no attribute 'set_scale'
