This sound like something is not quite right with the folders used... This can especially happen for dreambooth. Was this while trying to do dreambooth?

Dreambooth Lora training.

Try using the tool to prepare the folder structure for dreambooth. This will ensure all is proper for the training as far as folder names and all is concerned.

I did. Many times, but still getting same error. I didn't have that problem few days ago. I was able to start training.

accelerate launch --num_cpu_threads_per_process=16 "train_network.py" --pretrained_model_name_or_path="C:/Programs/stable-diffusion-webui/models/Stable-diffusion/sd-v1-4.ckpt" --train_data_dir="C:/train_data/100_wny style" --resolution=512,512 --output_dir="C:/train_data" --use_8bit_adam --xformers --logging_dir="" --network_module=networks.lora --text_encoder_lr=5e-5 --unet_lr=1e-3 --network_dim=8 --output_name="last" --learning_rate="1e-5" --lr_scheduler="cosine" --train_batch_size="1" --save_every_n_epochs="1" --mixed_precision="fp16" --save_precision="fp16" --seed="1234" --cache_latents --max_data_loader_n_workers="1" --gradient_checkpointing --xformers --use_8bit_adam

Found the solution.

Interesting. It works only, when I point to the folder where the folder with images is located.

So instead of:

/img/100_wny style

I choose:

/img

There is no images inside of folder /img. They are located only in /100_wny style folder.

So I don't understand what happened and before I didn't have to do this trick. Weird.

Folder 100_wny style: 700 steps
max_train_steps = 700
stop_text_encoder_training = 0
lr_warmup_steps = 70

Same issue and solution for me.
