I use the Anaconda Python distribution: Python 2.7 x64 with Windows 7 SP1 x64 Ultimate.
When I do import matplotlib.pyplot
I get ImportError: DLL load
I met the same error prompt. At last I found that I open the jupyter notebook in a different enviroment, not the enviroment that I used before. It means the module is not in your directory of your jupter noetbook enviroment. So I just open jupyter notebook in the original enviroment, the problem solved.
