sorry for nitpick

Suggested change

It seems like the test that failed on aarch64 + python39 might be flakey, because the python39 build does not fail on my x86_64-inux desktop. I'm going to poke a little bit at it, but if I don't see anything obvious I will just disable that test. I fixed the random seed, which is relevant for this tests (and lots of others in this package). Hopefully that helps.
