Torch2trt not above to locate CUDA_HOME

I am unable to install torch2trt from source(GitHub - NVIDIA-AI-IOT/torch2trt: An easy to use PyTorch to TensorRT converter), have installed the torch dependencies and NVCC version is visible(meaning the cuda path is specified). Getting the following error:-
:torch2trt$ python3 setup.py
Traceback (most recent call last):

OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.

Path is visible on bashrc:-
echo $CUDA_HOME
/usr/local/cuda-11.8

Move to “TensorRT” forum.
