Describe the issue

Hello,

I am training llava-mistral on custom dataset, but somewhere during training, I encounter the following error:

  train()
  File "/home/ubuntu/scripts/MoE-LLaVA/moellava/train/train.py", line 1465, in train
    trainer.train()
  File "/opt/conda/envs/moellava/lib/python3.10/site-packages/transformers/trainer.py", line 1537, in train
    return inner_training_loop(
  File "/opt/conda/envs/moellava/lib/python3.10/site-packages/transformers/trainer.py", line 1854, in _inner_training_loop
    tr_loss_step = self.training_step(model, inputs)
  File "/opt/conda/envs/moellava/lib/python3.10/site-packages/transformers/trainer.py", line 2735, in training_step
    loss = self.compute_loss(model, inputs)
  File "/opt/conda/envs/moellava/lib/python3.10/site-packages/transformers/trainer.py", line 2758, in compute_loss
    outputs = model(**inputs)

    result = forward_call(*args, **kwargs)
  File "/home/ubuntu/scripts/MoE-LLaVA/moellava/model/language_model/llava_mistral.py", line 68, in forward
    ) = self.prepare_inputs_labels_for_multimodal(
  File "/home/ubuntu/scripts/MoE-LLaVA/moellava/model/llava_arch.py", line 302, in prepare_inputs_labels_for_multimodal
    cur_image_features = image_features[cur_image_idx].to(self.device)
IndexError: list index out of range

So, I was wondering if anyone can help? Thanks

This problem most likely occurs because the dataset format does not follow the LLaVA format. You can check if your json annotation is consistent with LLaVA.
