Describe the bug
A clear and concise description of what the bug is.
The bug occurs when I use the official script for training:
D:\USERS\PYTHONPROJECT\pytorch-image-models-main> python train.py --data-dir dataset/transfires --epochs 50 --batch-size 64 --input-size 3 224 224 --opt adamw --lr 1e-3
--num-classes 2 --model resnet50
Training with a single process on 1 device (cuda).
Model resnet50 created, param count:23512130
Data processing configuration for current model + dataset:
input_size: (3, 224, 224)
interpolation: bicubic
mean: (0.485, 0.456, 0.406)
std: (0.229, 0.224, 0.225)
crop_pct: 0.95
crop_mode: center

@banpeiran are you sure you've synced the latest train.py script from here? Latest timm release with latest train script has no issues for me.

booted up windows test machine to check for any platform issues, there's no problem with current train.py
