Hi Hartmut,
I was hoping for you to show up and give your input. Thank you! I
appreciate you taking the time.

Since this is Python 2 I used this line:
exec -a "$0" /gnu/store/0n8ni2l…-python-2.7.13/bin/python -m site
The full wrapper looks like this:

Again with “python3” replaced as “/gnu/store/…-python-2.7.13/bin/python”
I ran this and wasn’t prepared for the deluge of output. The first time
statsmodels is mentioned is when the prompt appears and “import
statsmodels” is executed. Interestingly it goes straight to the old
statsmodels-0.6.1 instead of the newer one (0.8.0) which the wrapper
added to PYTHONPATH.

Note that “import site” is satisfied by Python 3, but the behaviour is
the same when I only keep Python 2 things on the PYTHONPATH.
With “-vvvv” I see that the directory containing statsmodels-0.8.0 is in
fact accessed multiple times for
“{site,os,posixpath,stat,genericpath,warnings}.{so,py,pyc}” and many
more; but when the time comes to “import statsmodels” it loads it
from the 0.6.1 directory; it does not look it up in the 0.8.0 directory.

Note that lib/python2.7/site-packages (which is on the user’s
PYTHONPATH) contains a file “python2-statsmodels-0.6.1.pth”. Does this
play a role here?

Unfortunately, this didn’t tell me much more than the previous command.
After numpy is loaded, the old statsmodels is loaded.

This is very good to know. I haven’t tested this (as I’m not editing
the store by hand), but I suppose we could create an empty pyvenv.cfg in
a profile hook when Python packages are installed.
(This wouldn’t help us much for wrapper scripts, though.)
