There is a problem when installing otmixmod using pip

[mbaudin47]

When installing OpenTURNS 1.24 against otmixmod using pip, the module does not load.

Consider the following setup.

$ mamba create --name testot124mixmod
$ mamba activate testot124mixmod
$ mamba install pip
$ pip3 install openturns==1.24 otmixmod

This prints:

Then execute the following Python script:

import openturns as ot
import otmixmod

produces:

This is a test on Windows.

yes, we should pin OT version next time, try otmorris==0.18 if you want to stick to 1.24
