Hardware and data requirements for model training.

What are the GPU requirements to run the training and approximately how many input videos should be used for training?

I would also like to know. I attempted training with an RTX 3060 and batch size of 1 and ran out of memory. I have 12 GB of dedicated GPU memory and 16 GB of shared GPU memory.

torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 114.00 MiB. GPU 0 has a total capacity of 12.00 GiB of which 0 bytes is free. Of the allocated memory 24.51 GiB is allocated 
by PyTorch, and 766.31 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation.  See documentation for Memory Management  (https://pytorch.org/docs/stable/notes/cuda.html#environment-variables)

I have stage 1 training running with my RTX 3060 and 64 GB of RAM. That's 12 GB of GPU memory and 32 GB of shared GPU memory totaling 44 GB of GPU memory. It seems to be just barely enough.

I've given up on training after reading the paper which said training was conducted with 8 NVIDIA A100 GPUs. My training time for stage 1 is approximately 1800 hours.
