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 fixed this on my Windows machine by adding [Anaconda]/Library/bin to my PATH.
I fixed this by installing libpng:
conda install libpng
Earlier I was also facing the same issue which is resolved by downloading the latest supported Visual C++ downloads redistributable files.
