I got the same error, I was using Ubuntu through WLS2
Looks like when I checked out the repo the pkl files didn't match the repo,

e.g. here is the contents of the rising_rivals.pkl
"version https://git-lfs.github.com/spec/v1
oid sha256:6ab71663c4df53fb9e87a099cc5a2f2268fb4a75c1585c038c0582e22b1024e4
size 34956"

I have never seen Git behave this way, will look into it and post an update when I know more

Very strange. Let me know how it goes. I use Git LFS for storing the reference models.

Very strange. It has been working on my linux machine. Could you send me the specs of the failing machines?

[vljukap98]

I am on Ubuntu 24.04.01 LTS, as wsl.
