python 3.8 or python 3.6

[zhaiyuan0217]

when I created the conda environment, i chose python=3.6, but in the environment when i run pip install -e . , it reminds "Package 'gdl' requires a different Python: 3.6.13 not in '>=3.8'". This code can't use python 3.6?

Same. I can't figure out how to get this installed, it's driving me crazy.

Since the EMOCA 2.0 update, it's recommended to use Python 3.8.

Let me know which part of the README caused this condition and I'll fix it.

Sorry for the confusion

I’m trying to use EMOCA V1 with an RTX 3090 on Windows or WSL. Every which way I attempt is another failure.

Now I’m just trying to get DECA to work first, and it’s also a no-go.

[radekd91]

WSL is quite a specific setup that I have never tested and so I imagine there can be plenty of things to go wrong there, especially with GPU related stuff. Pytorch and pytorch3d.

I would recommend installing EMOCA 2.0. The code will also run EMOCA 1.0

What‘s the vanilla OS for this? Linux, Windows?

[radekd91]

Everything was tested on Linux.

After much fighting, I got this to work on Windows 11, WSL 2, Ubuntu 22.04 with an RTX 3090. CUDA 11.7, Pytorch 2.0. What an adventure.

[radekd91]

Wow. Nice with. :-) Did pytorch 2.0 break anything? That's quite an update from the originally supported version.

A pull request would be very welcome.

I'm a beginner when it comes to GitHub and Pull Requests, so I'd need some help in learning what you want. I can outline a few changes I had to make.

• Start with this: https://github.com/radekd91/emoca/issues/44#issuecomment-1531581422

• Install a newer version of face_alignment. Do this before you install Pytorch.

• mamba install -c 1adrianb face_alignment==1.4.0

• There was an update to face-alignment, where you can't use _2D anymore, so....

• In the Python code, change any instance of "face_alignment.LandmarksType._2D" to "face_alignment.LandmarksType.TWO_D"

• It couldn't find all of the cuda files, so... #Add to Nvidia Paths, so it knows where to find cuda files export LD_LIBRARY_PATH=/usr/local/cuda-11.7/targets/x86_64-linux/lib/stubs:$LD_LIBRARY_PATH export LD_LIBRARY_PATH=/home/YOURUSERNAME/mambaforge/envs/work38/lib/python3.8/site-packages/nvidia/cudnn/lib:$LD_LIBRARY_PATH

#install pytorch conda install pytorch==2.0.0 torchvision==0.15.0 torchaudio==2.0.0 pytorch-cuda=11.7 -c pytorch -c nvidia #install pytorch3d pip install 'git+https://github.com/facebookresearch/pytorch3d.git@stable'

I think that's it. At least that'll get someone most of the way there.
