Matplotlib 1.4.3 broken on Windows

conda/conda#1753

Pls look into it, perhaps you can help with the _png import error.

File "C:\Anaconda3\lib\site-packages\matplotlib\mathtext.py", line 63, in
import matplotlib._png as _png
ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

_png is one of the complied c extensions which links to libpng. The problem here is probably that the version of libpng that your _png extension is built against is no longer available. This is 100% a packaging problem on binaries that we do not maintain. The linked conda issue or a new one is the correct place to take this up.

It's because why using libpng if matplotlib is using Pil/Pillow?

[mdboom]

matplotlib also uses libpng directly because it needs lower-level control of libpng than Pillow provides.
