8 months ago I encountered a similar issue as well. How about trying to run it with a batch size greater than 1 instead of 1? I resolved the problem by doing so!
Translation into advanced English vocabulary:
I too have faced a comparable predicament. Have you considered executing the script with a batch size exceeding 1? I personally overcame the issue by adopting this approach!

当我进行Progressive Fine-Tuning中的Stage 3: Fine-Tune DualStyleGAN on Target Domain时，输入命令：python3 -m torch.distributed.launch --nproc_per_node=2 --master_port=8765 finetune_dualstylegan.py --iter 1500 --batch 1 --ckpt ./checkpoint/generator-pretrain-003000.pt --style_loss 0.25 --CX_loss 0.25 --perc_loss 1 --id_loss 1 --L2_reg_loss 0.015 --augment cartoon 显示报错： Traceback (most recent call last): File "finetune_dualstylegan.py", line 539, in

请问这种情况应该怎么解决呢？
