batch inference supported?

Thanks for your amazing work! It's awesome!

I am wondering if batch inference is currently supported, as I noticed there’s a function called model.generate_from_batch in the example. The example code in the README file only demonstrates inference using a single sample.

Specifically, I am not sure how to concatenate the "images," "image_input_idx," and "image_masks" fields in the "inputs" provided to the model when dealing with multiple images of different sizes.

Batch inference is supported, you would need to run the process on several inputs and then concatenate the fields together while padding them with -1 so they have the same shape. We will look at adding automatic functionality for that.

@chrisc36 Can you please provide example code for streaming batched inference? :)

@d-rau allenai is working on adding support for this model in vllm. Seems like it should be in place soon.

https://github.com/vllm-project/vllm/pull/9016#issue

You should be able to run the branch that supports molmo even now if you're willing to tinker a bit with your vllm installation.

Hi @chrisc36 , I tried to do what you said regarding batch inference but the tokenizer's pad_token_id= 151643 and setting the pad value to -1, does generate attention_masks as required but it leads to an error when generate_from_batch() calls super().generate(...) in modelling_molmo.py, it leads to an error which I have attached below. This error does not happen if I choose a different padding value but then attention_mask does not ignore those tokens and the model generation consists of weird outputs. :

@chrisc36 I do think the batch processing should be handled in preprocessing_molmo.py though. Shall I open a PR for that or is it not worth it atm? I see there was a PR open for native transformers support.
