You should use mim install mmsegmentation

[junmeng6025]

pip install mmsegmentation works for me

[junmeng6025]

or try
pip install openmim
and then
mim install mmsegmentation

check this issue on stack-overflow: https://stackoverflow.com/questions/67666049/when-i-pip-install-mmseg-i-got-the-error-nameerror-name-reload-is-not-def

'reload()` is basically a Python2 issue
