IndexError: The shape of the mask [7387] at index 0 does not match the shape of the indexed tensor [1] at index 0

[14H034160212]

🐛 Describe the bug

The error exists when I try to use the qwen2-vl with qwen2-vl liger kernel to generate text.

The following code got the following error. But the same code if I change the liger kernel to qwen2 instead of qwen2-vl. It will correct.

Then I add the cache_position to the lce_forward function and it got the following error.

Here is the way I used qwen2 liger kernel.

from liger_kernel.transformers import apply_liger_kernel_to_qwen2
apply_liger_kernel_to_qwen2()

here is the way I used qwen2-vl liger kernel.

from liger_kernel.transformers import apply_liger_kernel_to_qwen2_vl
apply_liger_kernel_to_qwen2_vl()

Versions

transformers=4.47.1
liger_kernel=0.5.2

[Tcc0403]

cache_position is added to qwen2_vl in transformers v4.47.0

see: huggingface/transformers#34274

We have to update liger's flce_forward() in qwen2_vl.py to match the new implementation.

[BenasdTW]

cache_position is added to qwen2_vl in transformers v4.47.0

Thank you for the information. I'm experiencing the same issue with the latest version of transformers:
TypeError: lce_forward() got an unexpected keyword argument 'cache_position'

To work around this issue, you can downgrade the transformers by running:
pip install transformers==4.46.3
