Build, install and test custom scipy

Hello,

I am currently revising an old merge request (https://github.com/scipy/scipy/pull/13068) that I initiated a few years back. The “dev.py” file has disappeared and I cannot find an up-to-date tutorial on how to build, install (like a development package in a conda environment, so that I can easily iterate on the code) and run tests of my local scipy.

Do you have any hints ?

Cheers !

Use spin.

$ pip install spin

and then

$ spin build
$ spin ipython
$ spin test path/to/file::TestClass::test_func

and so on
