Running pytest after install pytest-monitor results in `FileNotFoundError: [Errno 2] No such file or directory (originated from sysctl(HW_CPU_FREQ))` about pytest-monitor HOT 6 CLOSED

Hello

Thanks for submitting! I think psutil is not able to handle CPU frequency on Apple M1. As I just get a brand new laptop, I'll check this intuition and strive to provide a fix quickly. :)

Thanks @js-dieu! Congrats on your new laptop. Hopefully it's not a complicated fix.

Seems not complex. However, psutil has released a version with support for M1 chipset.
Can you please give me the output of the following (to be run in your environment):

import memory_profiler as mp
import psutil as ps

print(ps.__version__)
print(mp.__version__)

It's strange that pip does not manage to give you the latest version of psutil .

Here's my output:

>>> import memory_profiler as mp
import psutil as ps

print(ps.__version__)
print(mp.__version__)
>>> import psutil as ps
>>> 
>>> print(ps.__version__)
5.9.1
>>> print(mp.__version__)
0.60.0

Ok, that means that psutil support of M1 is still partial. I am afraid we have to wait for them to fix this issue.

Hello @justinxzhao

I think that the latest release (1.6.5) should fix your issue. It is a fallback though, thus imperfect, but enough for you to run with pytest-monitor. Waiting for psutil to fix it completely though.
Do not hesitate to reopen if encounter another psutil related issue with pytest-monitor-1.6.5
