Bug / Crash for Spam

[josephsalmon]

Currently the code on main for spam leads to crashes:

@gdurif any idea why and when this started?

[gdurif]

Yes, the problem is the conda package python-spams (which I am not maintaining), potentially this one conda-forge/python-spams-feedstock#67

@mathurinm reported this here getspams/spams-python#17 and we are trying to solve the problem here #66

[josephsalmon]

sorry for the duplicate then from #66
I am closing this issue.

[gdurif]

We can keep this issue open until the problem is solved (since #66 is a pull request and it is possible to miss it while looking to report the problem)

[josephsalmon]

OK. I am reopenning it until proper résolution.

Not sure if this is related but now, running a benchmark with spams leads to the following error message on my machine:
