在运行python代码时，发现没有pytorch3d的包，下面记录安装过程：
 

直接进行pip安装是不行的：pip install pytorch3d 终端运行这个指令会报错如下情况：

ERROR: Could not find a version that satisfies the requirement pytorch3d (from versions: none)
ERROR: No matching distribution found for pytorch3d

下面经过查询，这个网址链接解决了安装pytorch3d的问题：

pytorch3d/INSTALL.md at main · facebookresearch/pytorch3d · GitHub

Installing prebuilt binaries for PyTorch3D

After installing the above dependencies, run one of the following commands:

1. Install with CUDA support from Anaconda Cloud, on Linux only

# Anaconda Cloud
conda install pytorch3d -c pytorch3d

在这篇博客的基础上：pytorch3d在linux下安装_pytorch3d pytorch3d/linux-64::pytorch3d-0.4.0-py38-CSDN博客

下面进行正确的pytorch3d安装： 

只需要在linux系统的终端环境中输入如下指令：

conda install pytorch3d -c pytorch3d

即可完成 pytorch3d 的安装
