PackagesNotFoundError

Clean Conda installation and Win64,
I get this:

did you ever get this resolved? torchvision==0.4.2 in particular is giving me this error; if i just install it without specifying a version then pytorch will fail

I got it running with the commands in the INSTALL file, not the environment.yml, but these were the issues:

• torchvision==0.4.2 is not in the pytorch channel anymore [https://anaconda.org/pytorch/pytorch/files?page=13] (I suppose it was removed). Closest one is:
  conda install pytorch==1.5.1 torchvision==0.6.1 cudatoolkit=10.1 -c pytorch
• I couldn't install mediapipe because it couldn't build opencv-python, as it tried to install the latest version which dropped support for Python 3.6.* (the one INSTALL mentions). Maybe you can update to Python 3.7, but what I did was:
  pip install opencv-python==4.6.0.66
  which is the last version to support Python 3.6.* and afterwards I installed mediapipe with
  pip install mediapipe.
  If you're going for FAN I think this isn't required at all, but maybe it helps someone.
  Maybe they are not the most elegant solutions, but I've got my *.OBJ file.

Related to this issue, I was getting this error when trying to install packages:

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

It looks like mediapipe no longer publishes a Python 3.6 package, and NextFace uses Python 3.6. The lowest version currently available is for Python 3.8. I changed the INSTALL commands to the following:

conda create --name faceNext python=3.8
conda activate faceNext
conda install pytorch==1.5.1 torchvision==0.6.1 cudatoolkit=10.1 -c pytorch
pip install redner-gpu
conda install -c conda-forge opencv
conda install -c 1adrianb face_alignment=1.2.0
conda install -c anaconda h5py
pip install mediapipe

That gets me past install, but it looks like the way numpy handles delimiters has changed, per numpy/numpy#22311 because I'm getting this error:
