import matplotlib._png as _png Import: Error: DLL load failed: The specified module could not be found

I fixed this on my Windows machine by adding [Anaconda]/Library/bin to my PATH.

I have had this problem as well. It seems to have cropped up in the last week or two. It seems like something in the scipy stack was compiled incorrectly. In the near term:

conda install anaconda

will roll your system back to a stable anaconda distribtution.

I fixed this by installing libpng:

conda install libpng
