Hi @weikengchen Thanks for the PR! Can you explain in more detail why this works? Thanks!

Yeah that sounds great. I added a .travis.yml file but I'm having trouble. I'm getting this error "Can not perform a '--user' install. User site-packages are not visible in this...

Ok I got it working. What do you think is the best way to use travis-ci to add python2 support?
