ImportError: DLL load failed: %1 is not a valid Win32 application for Python Matplotlib

>>> from matplotlib import pyplot as plt

Traceback (most recent call last):
  File \"\", line 1, in 
    from matplotlib imp         


        

Answer 1

On jupyter notebook I solved this problem by this way:

1. Install "numpy-1.11.0b2+mkl-cp35-none-win_amd64.whl" from this page.

2. If there is still no change, it's worth trying to reinstall matplotlib by pip.
