CentOS 7 box. As there's no package in any of the repos, we're trying to

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
and it still seems to want to write to system space: OSError: [Errno 13]

Anyone got any pointers?

First, this is a mailing list, not Outlook. Please don't top post.

Second, No. You do not appear to understand the issues.

I am *NOT* installing it as root. This is my manager's approach, and I
agree with it. As it's not a package, in a std. repo, it would not be
updated for bugfixes, and, far more critically, security fixes, when we do
that every month. That's why we want it installed in the user's space.

These are servers, used by many researchers, not someone's home Linux box.
And even at home, I wouldn't install it that way.

And I want him to use the system numpy, not install a newer one, that
would also have the same update issues. Btw, numpy in the std. repos
hasn't been seen a package update since 2015, which is why I'm trying to
install a scikit-learn from last year....

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.

And yes, I second that, system administration and maintaining one's own laptop are ultimately different things, luckily majority of my users refrain from telling me what they googled up about problem they report, but not everybody, so I definitely have the same feelings about the advice someone gave you ;-)

I hope, this helps.
