Installing auto-sklearn on Windows 10

First I would want to see why the pip isn't being found via the environment set up. (Assuming you're running a bourne-like shell), what do you get when you run command -v pip and echo $PATH in the virtual environment?

Second, if you want a workaround, just run pip from python directly.
python -m pip -V
Since the correct python is being found, this should work.
