An important hint on Pytorch3D installation

After getting tons of error for installing Pytorch3d, here is what worked for me:

You need to install PyTorch3D from source. So from [INSTALL.md], follow the steps:

• conda install -c pytorch pytorch=1.9.1 torchvision cudatoolkit=10.2
• conda install -c fvcore -c iopath -c conda-forge fvcore iopath
• conda install -c bottler nvidiacub and finally:
• conda install pytorch3d -c pytorch3d and it's done!

It also works for me, thanks for your sharing!

Thanks bro! This is incredibly helpful and time saving. Thanks for sharing! Tip for Nvidia 3000 series users, replace conda install -c pytorch pytorch=1.9.1 torchvision cudatoolkit=10.2 with pip install torch==1.9.1+cu111 torchvision==0.10.1+cu111 -f https://download.pytorch.org/whl/torch_stable.html

Also if given conda errors of pytorch3d not found

In x64 Native Tools Command Prompt for VS 2019:
set DISTUTILS_USE_SDK=1

pip install "git+https://github.com/facebookresearch/pytorch3d.git"

I found another problem. I can install pytorch3d using the above method. But after installing pytorch3d and kornia module, I got the error showed in https://github.com/YadiraF/DECA/issues/159. I tried many times and found the problem occurs when I install pytorch3d and kornia together.

After many tries, I solved the problem following the steps.

1. pip install pytorch3d (get related modules for pytorch3d, this version of pytorch3d is too old, will update in last step)
2. pip install -r requirements.txt (should add importlib-metadata?)
3. pip install 'git+https://github.com/facebookresearch/pytorch3d.git@stable' (update pytorch3d version to the lastest)
4. run demo successfully
