Benchmarking fails on M1

[mikasenghaas]

Hi, firstly, thanks for the great repository! I wanted to use it to benchmark various image and video classifiers for my bachelor project, but ran into problems when running benchmark. The psutil.cpu_freq() call in get_machine_info fails because of a file missing on M1 Macs. It is a known, but (as far as I can tell) unsolved issue of the psutil (tested with almost latest version v5.9.4 repository (see this Issue)

As a quick and dirty fix I just hard-coded the maximum clock speed of my local machine, but it might be nice to find a programmatic cross-platform solution.

Reproducing the error in psutil dependency in Interactive Shell:
