⚡ Recommended focus areas for review Typo There is a typo in the installation command for the nightly nvfuser pip package. The command should be pip install --pre nvfuser-cu128 --extra-index-url https://pypi.nvidia.com instead of pip install --pre nvfuser-cu121 --extra-index-url https://pypi.nvidia.com. You can install a nightly nvfuser pip package built against torch nightly code base with Typo There is a typo in the description of the optional dependency for the nightly torch wheel. The text should be "optional dependency" instead of "optinoal dependency". we have explicitly marked the nightly torch wheel as an optional dependency. Outdated CUDA Version The CUDA version cuda 12.4 is not listed in the new release matrix. Ensure that all relevant CUDA versions are included. built-env | cuda 11.8 | cuda12.6 | cuda 12.8
