Running Unlimiformer with the `forward` method

[testzer0]

Hi, I am currently trying to run the inference example with a slight modification. Instead of generate()-ing text, I want to pass in input_ids and labels to the forward function and obtain the logits. However, the current implementation leads to device-side asserts. How may I achieve the above goal?

Hi @testzer0 -- what is the specific error you're seeing here? Thanks!

I also have issues with running forward method:

AttributeError: 'UnlimiformerBART' object has no attribute 'input_ids_size'

Here is my colab (based on inference-example.py) for more details and being able to reproduce error.

Thank you!
