We've been building a custom model for the past month and it has been training fine until the last two attempts. We're labeling inside of Doc Intel Studio, ensuring all documents are labeled.
We've gotten this error InternalServerError: An unexpected error occurred twice after the span of a few days.
Any tips to look at? I'm on a pay as you go plan currently.

Greetings and Welcome to Microsoft Q&A! Thanks for posting the question.
Based on the error message you received, it seems that an unexpected error occurred while training your custom model. This error message is not very specific, so it can be difficult to determine the exact cause of the issue. However, there are a few potential solutions that you can try to resolve this error:-
- Try training your custom model again and see if the error persists. If the error persists, try reducing the number of labeled samples (possibly 5).
- Please make sure all input requirements as mentioned here.
- Ensure your subscription has enough resources and verify you’re not exceeding quotas on a Pay-As-You-Go plan to avoid training issues.
- Check that your training data size meets Azure Document Intelligence requirements, as very large or small datasets.
I Hope this helps. Do let me know if you have any further queries.
Thank you!
