There is a problem：cannot import name '_C' from 'pytorch3d'

I followed these command lines to complete the download：
git clone https://github.com/facebookresearch/pytorch3d.git
cd pytorch3d
git checkout -f v0.7.2
pip install -e .

But after downloading, the above problems occurred

Please give us more details about your environment (e.g. conda list and pip list). It is important that nothing changes between the build (e.g. the pip install -e .) and the attempt to run. For example, the versions of cuda and PyTorch, which need to be working before the build is performed, must be exactly the same. This error usually reflects something about these which has changed.

this repo needs some serious work there are countless people with version issues and installation issues.

@jez-moxmo Many people use PyTorch3D successfully, and I think the installation instructions for /supported/ platforms are easy to follow. Some other people want to use the library in unsupported ways, either deliberately or not, and they in particular might need help, and sometimes will get it. That's not itself a sign of a problem. Do you have an issue you need help with?

我也遇到这些问题，就算pip install -e .也会遇到_C找不到。我的环境是ubuntu 18.04 python3.9 cuda11.3, torch1.10.2, 找了好多版本的pytorch3d，最后定位在了pytorch3d 0.6.1和cub 1.10.0。安装前首先得配置CUB_HOME的环境。然后，我没有pip install -e.，我用PyCham打开pytorch3d这个文件夹，然后以setup.py配置了个运行环境，先setup.py build, 然后 setup.py install。然后_C就没这个问题了。然后我在不更改CUB_HOME的情况下，也试了pytorch3d0.7.2和0.7.8,也都可以安装到我的环境里，没有_C的问题。
