Running

python py/desisim/test/test_lya.py

yields the following non-catastrophic warning:

<frozen importlib._bootstrap>:219: RuntimeWarning: numpy.ndarray size changed, may indicate binary incompatibility. Expected 80 from C header, got 88 from PyObject

This is happening on my laptop (a newer MacBook Pro) with python 3.8.5 and numpy 1.20.3 but I'm also seeing it in our Github Actions tests.

Googling suggests that simply reinstalling numpy should fix it, although it didn't work for me: https://stackoverflow.com/questions/66060487/valueerror-numpy-ndarray-size-changed-may-indicate-binary-incompatibility-exp

This isn't a critical issue, I'm just curious whether anyone else has seen this and/or has a suggested fix.
