Who can help?

I tried to run the colab notebooks for qwen3_5 models which are auto-generated. The inference takes forever. I figured out this issue is due to the specific image that is automatically inserted => "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG". The inference works fine for other images (like the one used for model test).

Can someone from the community please investigate and fix the exact issue. It should not be a very difficult as it's most likely related to how this model handles images of different dimensions.

Information

  • The official example scripts
  • My own modified scripts

Tasks

  • An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
  • My own task or dataset (give details below)

Reproduction

Go to the auto-generated colab link from the model repo https://colab.research.google.com/#fileId=https%3A//huggingface.co/Qwen/Qwen3.5-0.8B.ipynb

Expected behavior

Inference will not loop forever for this specific image.

extent analysis

TL;DR

The issue can likely be resolved by preprocessing the specific image "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG" to match the expected dimensions handled by the qwen3_5 model.

Guidance

  • Investigate the image dimensions of "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG" and compare them with the dimensions of images that work fine with the model.
  • Preprocess the problematic image to resize it to the expected dimensions before passing it to the model for inference.
  • Verify that the model handles images of different dimensions correctly by testing it with images of various sizes.
  • Check the model's documentation or source code to see if there are any specific requirements or limitations for image dimensions.

Example

No code snippet is provided as the issue does not contain enough information about the model's implementation or the preprocessing steps.

Notes

The solution may not apply if the issue is not related to image dimensions, but rather to other factors such as image content or model configuration.

Recommendation

Apply a workaround by preprocessing the image to match the expected dimensions, as this is likely to resolve the issue without requiring changes to the model or its configuration.
