wc_vid2vid: FileNotFoundError: [Errno 2] /mnt/bigdata01/datasets/wc_vid2vid/cityscapes/train/lmdb

[Skyrelixa]

Hello! Thank you for your hard work in making this repository of open source code available for researchers.

I'm in the training stage for wc_vid2vid using the cityscapes dataset. I've formatted the data appropriately, successfully created the LMDB format for training, and then ran: python -m torch.distributed.launch --nproc_per_node=1 train.py --config configs/projects/wc_vid2vid/cityscapes/seg_ampO1.yaml

However, I'm encountering the following runtime error: /home/ubuntu/avatar/lib/python3.8/site-packages/torch/distributed/launch.py:178: FutureWarning: The module torch.distributed.launch is deprecated and will be removed in future. Use torchrun. Note that --use_env is set by default in torchrun. If your script expects--local_rankargument to be set, please change it to read fromos.environ['LOCAL_RANK']` instead. See https://pytorch.org/docs/stable/distributed.html#launch-utility for further instructions

I am currently working in a python3.8-venv because of updated dependencies (PyTorch). And if it's as simple as changing the path for the directory, where and how do I change the path?

Any reply will be much appreciated!

@Skyrelixa Update this file configs/projects/wc_vid2vid/cityscapes/seg_ampO1.yaml with the actual location of your lmdb files.

@digvijayad Thank you! This works perfectly. Closing the issue.
