- pip uninstall torch
- pip install torch==2.7.1 --index-url https://download.pytorch.org/whl/cu128

Let me know if this solves your problem!
Done, but sorry no. The game is exactly the same: same moves played, same mate on move 57, same score 87/114 random moves (76.32%). This, of course, also means the randomizer doesn't work. Maybe irrelevant, I noticed the .bat command: cd %~dp0 fails. The engine is successfully launched from the path it is installed in, and python is found thanks to the 'path' string content.

Some additional investigations, in order to better check my Python setup:
- I tried running v0.3, looks much more successful: autogame ended with: 14/55 random moves (25.45%)
- I then also tried v0.2, I mean your package instead of JA's bundled one I used so far: after installing transformers using pip, it runs fine. No random moves reported. Plays very similar to JA's package (very few moves deviations).
Thanks again for the kind help!

Please see my previous post at the end of page 2. There was a bug that has now been fixed. I also managed to package the engine into a single executable file, so hopefully it will work this time!

Thanks for spotting that (cd %~dp0). I'll look into it. Which OS do you use?

Hi David,
while I was testing I missed your bug-fix post. Great, both your fixed Python package and the single exe work perfectly, test auto-game said: 0/154 random moves (0.00%). :D
My OS is: Windows 11 Professionnel v.22H2

Thanks for the great support!
