Hi!

Where can I download the BT5-1024x15x32h-rpe-swa-2647500.pb.gz network and other BT5 nets?

Thank you!

This link will download a BT5 net directly ... https://plutie.ca/lc0/BT5-1024x15x32h-r ... 0000.pb.gz

BT5- nets (that I know of) need special Lc0- compiles to be run. Github- 0.32.0 and 0.32.1 don't work, so far I didn't find any ready to use Cuda- compile to be downloaded for free neither, regards

Thank you very much! But apparently it doesn't work on my GPU (RTX 4060). Or maybe I did something wrong. I just imported lc0 32.1 into Arena 3.51 and set the weight (as I do with BT4 and earlier versions). I also tested lc0 dag, neither of them make any move.

On a side note...Do you have the files to run onnx-trt ? If so, I have a binary that works with BT5 (the same one from TCEC S28 - Division P) https://tcec-chess.com/#div=p&game=1&season=28 Just let me know if you need that binary.

Hello, I would be interested in LcZero 0.31-dag-4d98c58 with the gpu-nvidia-cuda12 environment

Like I said, that version works with onnx-trt not cuda.

Having to install TensorRT e.g. from here?

Hey Peter,

The easiest way to do this is to download lc0-v0.32.1-windows-onnx-trt https://github.com/LeelaChessZero/lc0/r ... nx-trt.zip. Unzip. The readme inside explains what to do. If you run into any problems let me know.
