KeyError: 'throttle.io_service_bytes in container python:3.8.17-slim
Hi, thanks for providing this library. I unfortunately got the following error while running inside docker container which is given in the title.
$ ./cgutil top -i -n 2 -b

KeyError: 'throttle.io_service_bytespip install does not install latest released version from pypi.org
- reproduction:
pip3 install "cgroup-utils"
# version 0.5 is trying to get installed but fails because 0.5 is not py3 compatible
pip3 install "cgroup-utils>=0.6"
# fails because pip says there is no 0.6
- while debugging i found that:
https://pypi.org/simple/cgroup-utils/only lists package versions 0.3, 0.4, 0.5, but while cross checking with other pypi packages latest version is always in "/simple"
Gentoo will be removing dev-python/cgroup-utils
Any chance of updating for compatibility with Python >=3.7 ?
