conda create -n pytorch3d python=3.8 conda activate pytorch3d conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=10.1 -c pytorch conda install -c conda-forge -c iopath fvcore iopath conda install -c pytorch3d pytorch3d
版本全要对齐，尤其注意cudatoolkit=10.1，可以避免一系列奇怪的报错！！
另一种，方法，如果显卡是3090等一定要基于cudatoolkit11.0以上的，需要用wheels安装
