Error on running "Predict Rig" on Linux

[EvgenyRodygin]

Hi and thanks a lot for this great addon (which I'm not able to test out yet :D)
I have the following issue and would be really glad if you could help somehow:

System: Ubuntu 20.04, Blender 2.93
I have followed the instructions but slightly updated package versions. Installed CudaToolkit 11.1 + Pytorch 1.8.2 (tried 1.10 as well)
The addon is installed correctly. It sees CudaToolkit (when I run Blender through cmd). The modules are installed with Conda + python 3.7 (tried virtualenv as well) and are ok in Blender:

The problem arises when I press "Predict Rig" button. That's what I have:

Error: Traceback (most recent call last):

ImportError: Failed to load PyTorch C extensions:
It appears that PyTorch has loaded the torch/_C folder
of the PyTorch repository rather than the C extensions which
are expected in the torch._C namespace. This can occur when
using the install workflow. e.g.
$ python setup.py install && python -c "import torch"
This error can generally be solved using the develop workflow
$ python setup.py develop && python -c "import torch" # This should succeed
or by running Python from a different directory.

hi, I came across this exact problem recently.
it seems the fix to this problem is to align the python version with that in blender.
I'm using blender-3.2.0-linux-x64 (it comes with python3.10), my machine has CUDA-11.7 with Nvidia driver 515.43.04. my conda environmen is created by:

conda create -n brignet python=3.10
conda activate brignet

I installed torch-1.11.0 with CUDA11.3 using pip command, and here is my "pip list | grep torch":

torch              1.11.0+cu113
torch-cluster      1.6.0
torch-geometric    2.0.4
torch-scatter      2.0.9
torch-sparse       0.6.13
torch-spline-conv  1.2.1
torchaudio         0.11.0+cu113
torchvision        0.12.0+cu113

Hello, after installing according to your configuration, Blender cannot recognize torch, torch cluster, etc.
