weave not working with anaconda

[Krzysiaczek99]

recently i tried weave with python 2.7 (64 bit) from anaconda and i come to multiple issues.

see Stackoverflow question

https://stackoverflow.com/questions/54764514/weawve-importerror-dll-load-failed-1-is-not-a-valid-win32-application-anacond

additionally i tried to test the distribution from command line with nose for both python 2.7 from anaconda and python 2.7 32 bit (XY) amd it also fails

ENo module named msvccompiler in numpy.distutils; trying from distutils

[rgommers]

Possibly due to a recent change in Anaconda, but I'm not sure - could be that this never worked. Looks like your GCC is not the Anaconda-shipped one, which will be problematic.

Note that weave is end of life, so this is unlikely to get fixed.

[rgommers]

@Krzysiaczek99 Anaconda just reverted a change to how DLL loading works. Can you try if conda update python fixes this issue for you?
