Re: what happened to scorpio NN in TCEC?

From what I gather it is not the fault of Scorpio but cutechess-cli. Apparently cutechess-cli only waits 10 seconds for an engine to load but loading Scorpio neural networks may take upto 30 seconds. It is not a problem for winboard if an engine takes an hour to initialize because the winboard prot...

Re: Any Fortran coder ?

If you work in the profession as a developer or devops or other person who codes partially or wholly for a living, I suggest you pick another language. C and C++ are the standard languages I am aware of that most of the modern chess programs I have seen have been written in. I code with fortran for...

Does it loses many elo points when using int8 precision calculations?
Actually TensorRT does not seem to support with UFF files generated from Tensorflow pb files,
so I wound't know if there would be a significant loss in accuracy.

Re: Scorpio 2.8.9 with TensorRT support

You need to add the path to egbbdll in the "Path" environment variable.

After that please also set mt=128 and use delay = 1 in the scorpio.ini

Re: 3 million games for training neural networks

Are those 2M positions available? Those are 770k position from quiet_labeled.epd (zurichess), and 1.x million pos from Alvaro that everybody here has. I don't know why I am not able to beat those networks from PGN-trained networks so far... I just tried Cheng's 12 million positions metnioned in thi...

Re: 3 million games for training neural networks

Perhaps collections like high level TCEC games would be useful for training. They have scores attached to each position. That should give very high quality answers for the actual value of a position. Yes, I think that is what I need. Training from PGN games using the result tag just doesn't seem to...
