git clone https://github.com/linkedin/Liger-Kernel.git

@tjtanaa can you help take a look? thanks!

@agunapal
You will also need to pass the url when installing. E.g.
pip install -e .[dev] --extra-index-url https://download.pytorch.org/whl/nightly/rocm6.2

@ByronHsu
Should we add this into the README.md. I remember when the first PR to support Liger on ROCm, there are installation instruction in the README.md. However, at some point when the README.md was cleaned up, the installation command for ROCm has been removed.

Sounds good! @hebiao064 can you help modifying readme?

@tjtanaa Yes it might be dropped by me when we switched to dynamic installation of setup.py

Would you mind help us test whether this PR works on ROCM? #572
