Python virtualenv install scipy

Question

I'm trying to install scipy with pip on a machine I have limited access to, I can't run any sudo or apt-get commands. I made a python virtual enviroment and installed numpy in it, so far so good. But when I try to install scipy , I get "no lapack/blas resources found".

I tried to run

$ export LAPACK=/usr/lib/liblapack.so.3
$ export BLAS=/usr/lib/libblas.so

And then install scipy, but still get the same error. There is also liblapack.so.3gf and libblas.so.3 , libblas.so.3.0 and libblas.a , should I export any/either of those?

I've seen number of threads about this, but almost all of them include apt-get . I know that BLAS/LAPACK is installed on this machine, but I'm just not familiar enough with Linux to know exactly where the problem is.

In general virtualenv does not work well with different versions of compiled extensions. If you want to have different versions of scipy & numpy installed simultaneously, the best tool is conda . See this page for info on creating conda envs, which are like virtual envs but can handle non-python dependencies in a sane way.
