gentoo-overlay

My personal overlay for Gentoo on WSL.

Mainly maintained packages

• Pytorch
• Tensorflow
• Some NVIDIA SDKs, such as cudnn, nccl, cusparselt and tensorrt.
• and relative packages (torchvision, lightning, ...)

Difference from offical overlay

• pytorch and tensorflow are built with CUDA-12
• pytorch is built with NCCL and Magma support
• tensorflow is built with NCCL and TensorRT support
• In order to build tensorflow, re2, grpcio, grpcio-tools, abseil-cpp, protobuf, protobuf-python and onnx are built with C++17 here, whereas they are built with C++14 in offical overlay. See discussion in this pull request.

Notations about Tensorflow

There is something strange with tensorflow-2.14 and tensorflow-2.15, see #62002 and #62075. This will not prevent tensorflow from running, and seems not to be significant. But tensorboard starts really slow with version 2.15.0 due to this error. So the current suggestion is to stick to version 2.13 (with keras 2) or update to version 2.16 (with keras 3).

With version 2.17, these warnings come back again.

Futhermore, I cannot build Tensorflow 2.18.0 with non-hermetic python. Maybe 2.17.1 is the last supported version.
