[pradeepdev-1995]

The installation command i tried

pip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --global-option="--cpp_ext" --global-option="--cuda_ext" ./

But it gives the error

/opt/conda/lib/python3.10/site-packages/pip/_internal/commands/install.py:283: UserWarning: Disabling all use of wheels due tothe use of --build-options / --global-options / --install-options.
