Get outputs of cpp/tensorrt_llm/kernels/cutlass_kernels/python/generate_kernels.py

[YLGH]

Hey folks,

I couldn't find out how to run cpp/tensorrt_llm/kernels/cutlass_kernels/python/generate_kernels.py. Does someone happen to have its outputs? I didn't have too much luck installing cutlass_library

generate_kernels.py is a code-generation script that depends on the CUTLASS Python code generation utilities (such as cutlass_library). The generated files are typically not checked into the repository, so you'll generally need a working CUTLASS installation to regenerate them.

If you're having trouble installing cutlass_library, here are a few things you can check:

• Make sure you're using the version of CUTLASS expected by the TensorRT-LLM commit you're building. The required CUTLASS revision can change between releases.
• Initialize and update submodules if you're building from source:

  git submodule update --init --recursive

• Ensure that the cutlass/python directory (or wherever cutlass_library resides for your CUTLASS version) is available in your PYTHONPATH.

If your goal is simply to build TensorRT-LLM rather than modify the kernels, it's also worth checking whether your specific release already includes the generated sources or whether your build process invokes the generator automatically.

Unfortunately, I don't have the generated outputs to share, and they can vary depending on the TensorRT-LLM version and the corresponding CUTLASS revision. If you let us know the exact TensorRT-LLM commit or release you're using, it would be easier to point you to the correct CUTLASS version or determine whether the generated files should already exist.
