I tried a small batch size 16. Same results.

Thanks for checking out the code! I actually could not reproduce this error.

Does the problem still persist? If so, please let me know you have tried some debugging or got some more info, e.g., printing optim_slice.stop - optim_slice.start, len(self.tokenizer), etc. The gradient shape [20, 32000] looks correct.

Given that I could not reproduce it, I'm wondering if it has to do with transformers version. If you have not already, please make sure that the version is transformers==4.35.2.

• Could you please update the requirements.txt file? In current version, using transformers==4.34.1.

• len of tokenizer: 32001

Could you please update the requirements.txt file? In current version, using transformers==4.34.1.

Updated! Thank you for catching that. I will close the issue for now assuming that versioning was the issue. Please feel free to reopen if the problem remains.
