Where can I find the onnx-trt version of Lc0?
onnx-trt
is an experimental backend for Lc0, it’s not yet included in the
official releases. This is the version that played TCEC Cup 15. Note that it’s
only beneficial for very high-end GPUs (i.e. RTX 5000/6000 series), and only for
bigger nets. Also note that the version that we compiled for TCEC doesn’t have
other backends working (like cuda
).
The binary can be taken from this build artifact.
You’ll also need to download the onnxruntime
from here
Windows
or
Linux.
Next, you need to download the TensorRT and CuDNN DLLs, then add them to your PATH or the directory containing the lc0 binary.
