Bad marshal data YoLo model

I tried to run a project from repo and got the following log which, I believe, tells a problem with weights load.

python3 main.py

ValueError: bad marshal data (unknown type code)

I use python 3.8.5 and latests TF Keras for cpu. Is there a way to fix it? (load other weights or smth)
