Has anyone else had this error with psutil?

Seems to be a problem with my psutil version on Mac OS. My current version is 5.6.3.

This illustrates the root of the problem:

Or, maybe I shouldn’t be trying to run this example on Mac OS with CPUs?

Looks like examples/example_1.py seems to be the best place to start. This is working now. Thanks.

Thanks. This makes sense. Maybe I shouldn’t be trying to run this example. What’s a good example script to get me started on Mac OS X with CPUs? (I’m just trying out this package for the first time and will transition to a linux-GPU machine once I figured it out).
