Hi everybody

They have guide to install on Mac and Linux, but not Window, i been searching around internet too, but no luck.
Anyone gone through this yet? Thanks :wink:

So if you don’t need these to work inside Maya.

You should be able to download a version here http://www.lfd.uci.edu/~gohlke/pythonlibs/

Though it looks like its included in the PyAlembic installer, but not by itself. Very weird.

If you do need this to work in Maya, you’ll need to get the source, and proper build-chain up and running and then compile it yourself.

Kaij’s page links back to pythonlibs. Looks like the guy no longer host the file himself.

Installing the ones provided here may be a better option. Looks like it requires VS 2008 Express to fix the error vcvarsall.bat not found.
