Problem with integrating BERT (tensorflow.python.framework.errors_impl.InvalidArgumentError: indices[0,512] = 512 is not in [0, 512))

[MajaRolevski]

Rasa version: 1.10.7 (also tried with 1.8.3)

Python version: 3.7

Operating system (windows, osx, ...): Linux and Windows

Issue: I have a problem with integrating BERT into the configuration of my model. Namely, at the very beginning of training it gives the error message shown below. There is also a config.yml file I used.

It is interesting that I am not getting this error when using a very small train dataset, so the model is able to finish with training successfully.

Error (including full traceback):

Thanks for raising this issue, @tabergma will get back to you about it soon✨

Please also check out the docs and the forum in case your issue was raised there too 🤗

[tabergma]

@MajaRolevski Thanks for raising the issue. How small is your "very small dataset"? And how does your "normal" dataset look like that resolves in this issue?

[MajaRolevski]

@tabergma Thank you for the answer. My "very small dataset" consists of 19 classes (intents); each class has 10-30 sentences, except one that has 347 sentences and the other with 1897. On the other hand, the "normal" dataset contains 19 classes, where each class has on average 70-100 sentences, except one with 1565 and the other with 41564 sentences.

@MajaRolevski Looks like your dataset has some sentences which are very long(>512 tokens). We'll add a fix soon so that the training doesn't break because of this but I would also suggest you to sanitize your data and possibly clean up such sentences because they are unusual and could be very noisy for training.

[hotzenklotz]

We are facing the same issue. Our response selector has some rather long answers, so we run into the BERT token limit as well. When I shorten my answers, the model trains fine again. It is hard to find a good cut off length for the answers though with the different tokenizer and libs involved.

I am looking forward to fix for this :-)

[hotzenklotz]

@dakshvar22 Thanks for fixing this. Will the fix be available for Rasa version 1.10.x or only Rasa v2?

any news on it? i'm facing with this problem

[zr-smile]

i'm facing with this problem too，

tensorflow.python.framework.errors_impl.InvalidArgumentError: indices[3453,0] = 1780522202 is not in [0, 120000) ----[[node net_input/embedding/embedding_lookup_55 (defined at ./check_ctr_v1.py:410) ]]

I define tf.saved_model.loader.load(sess, [tf.saved_model.tag_constants.SERVING], self.saved_model_dir) in check_ctr_v1.py:410

[SamMohel]

Did someone solve it , please ?

[zr-smile]

您好，您的邮件已收到，我会尽快查看，

What could be the possible solution, or just a try except situation to handle.
