Question

I'm trying to install glmnet using these instructions. When I run python setup.py and I choose the interactive option to build, I get the following Could not locate executable XXX errors. I've installed scipy and numpy via pip.

Answer 1

The Could not locates aren't really errors. It's unlikely that a package would require you to have 5 different fortran compilers installed.
