error after using the command 'poetry install' and 'poetry run python setup.py install' to install all python dependencies.

This is such an amazing project,But I got an error after using the command 'poetry install' and 'poetry run python setup.py install' to install all python dependencies.

It is
'Current Python version (3.7.13) is not allowed by the project (=3.8).
Please change python executable via the "env use" command.'

But READEDME.md required ' Install using poetry prerequisite install python 3.7, poetry and ffmpeg'
Should I modify the current python version 3.7.13 to 3.8？ Will this affect the project?
Supplementary Note：I have successfully installed Poetry (version 1.2.0) and other prerequisite .My CUDA version is 11.1，python 3.7.13，ubantu 18.04.
I hope to get your reply, thanks!!!

I have tried changing the current python version 3.7.13 to 3.8. Then I got another error after using the command 'poetry install' and 'poetry run python setup.py install' to install all python dependencies.
