CentOS 7 box. As there's no package in any of the repos, we're trying to install scikit-learn in the user's space. It refuses. My late try
was,
after d/l a .whl from last year, hoping that would work with the numpy package in the regular repos, I did a pip install --user scikit-learn..., and it still seems to want to write to system space: OSError: [Errno 13] Permission denied: '/usr/lib64/python2.7/site-packages/numpy-1.7.1.dist-info
Anyone got any pointers?

Mark, python is a "sneaky snake" ;-) and some modules may require particular version of dependencies, therefore they may ignore your system wide numpy (even though it may just may be compatible with them), and may demand latest version of numpy. Which will explain pip (or other) attempting to pull dependencies which allegedly are available system wide already.
Just speculating, your own research on your particular issue may give your better answer.
<snip> Well, my manager came back, and he's got me using virtenv. Having read about it, I like it. Oh, and the issue with the system numpy in site-packages was that, for some reason, it was *not* world-readable. Fixed that.
So, I'm working on trying to install scipy in the virtenv... and for unknown reasons, it simply can't find the system libs. I did this before the last attempt to export LAPACK=/usr/lib64/liblapack.so.3 export BLAS=/usr/lib64/libblas.so.3 and just added export LD_LIBRARY_PATH=/usr/lib64 Still can't find them.
Clues on this one?
