Training on A6000 with CUDA 11.7

[DarylWM]

Hello. Thank you for sharing this code; I think it's really interesting work and I'm keen to try it for my dataset. To get started, I'd like to train the example on an A6000 using CUDA 11.7. I tried the specified versions in the environment.yml but need to bump up the CUDA version to get A6000 support. I get this error:

train.py:1301: DeprecationWarning: Starting with ImageIO v3 the behavior of this function will switch to that of iio.v3.imread. To keep the current behavior (and make this warning disappear) use `import imageio.v2 as imageio` or call `imageio.v2.imread` directly.
  return imageio.imread(f, ignoregamma=True) if f[-4:] == ".png" else imageio.imread(f)

Here are the Torch versions I'm using:

torch               1.13.1+cu117
torchaudio          0.13.1+cu117
torchvision         0.14.1+cu117

I'm new to Pytorch so I'm wondering whether there's a global fix or do I need to go through and check where the tensors are allocated?
