I encountered the following problem when I installed implicit about implicit

[benfred]

I don't have easy access to a windows box - so this is a little hard for me to test. However, we do have CI set up for windows that builds this package and runs the tests: https://ci.appveyor.com/project/benfred/implicit

Can you include the complete build output? Also what compiler are you using and what version of python?

my python version is 3.5.4

Interesting -

Do you have visual studio installed? Also is it on the PATH ? This question has some steps you can take with someone else having a similar problem https://stackoverflow.com/questions/41724445/python-pip-on-windows-command-cl-exe-failed
