i followed the steps given bellow and i am stuck at this error can you please tell me what i can do here

conda create -n pytorch3d1 python=3.8
conda activate pytorch3d1
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch
conda install -c conda-forge -c fvcore -c iopath fvcore iopath
conda install -c bottler nvidiacub
conda install pytorch3d=0.4.0 -c pytorch3d

bash install.sh dint work and gave me the error from this post.

#10 (comment)

i solved that by addint "'--version" instead of "-v"

then i did

cd FastMinv/
994 python setup.py install
995 CUDA_HOME='/usr/local/cuda'

still the same error as above and then

pip isntall -e .
nothing changed in the error
