I have a similar issue with the LSUN dataset:
trainlsun = torchvision.datasets.LSUN(root='/data', classes=['bedroom_train'], transform=transform)
yields
Error: /data/bedroom_train_lmdb: No such file or directory
eventhough this class argument is reported by the authors: https://github.com/pytorch/vision/blob/master/torchvision/datasets/lsun.py 176 (line 66)
I am running pytorch 0.4.0, torchvision version seems to be 0.2.1 (I picked the latest nvidia-docker image)
Has anyone met this issue and solved it ?
Thanks
