Matplotlib issue arise when importing tensorlayer #79
Description
I am working with conda environment. After installing tensorlayer, I tried to import it: import tensorlayer as tl, but got such an error:
Traceback (most recent call last):

ImportError: Matplotlib qt-based backends require an external PyQt4, PyQt5,
or PySide package to be installed, but it was not found.
This issue is not supposed to arise with conda. When I import matplotlib individually, it works well. I wonder how can I deal with this issue. Thanks in advance!
