when I train the casmvsnet in BlendedMVS dataset using command python3 train.py, I got this error "RuntimeError: received 0 items of ancdata " at 94% of epoch 0, I was following the Installation and Download the dataset(s) in README to prepare my environment and data.

Hi, according to here it may happen on specific machines due to the multiprocessing approach implemented by pytorch, you may try to:

increase the maximum number of file descriptors with ulimit
reduce the number of workers the dataloader uses https://github.com/andreaconti/multi-view-guided-multi-view-stereo/blob/dbca718c95491bc21e08dbbedf92aae67433d4e6/guided_mvs_lib/datasets/__init__.py#L21

Hope it helps
