MedSegDiff error in training

Hello, author, I made a mistake in training. What is the specific reason for the error?

python scripts/segmentation_train.py --data_name ISIC --data_dir F:\liuxiao\project\dataset\isbi_3b_medsegdiff --out_dir F:\liuxiao\project\MedSegDiff\outdir --image_size 256 --num_channels 128 --class_cond False --num_res_blocks 2 --num_heads 1 --learn_sigma True --use_scale_shift_norm False --attention_resolutions 16 --diffusion_steps 1000 --noise_schedule linear --rescale_learned_sigmas False --rescale_timesteps False --lr 1e-4 --batch_size 8

error: The above exception was the direct cause of the following exception:
