Model Build Error: Invalid label

sripadh puligilla 0

I have built a custom form recognizer model using the Azure storage explorer path to extract the files and brought in the files to build tables for this model. I have used a sufficient number of documents for training as well, but once I hit 'Train', I am getting the following error:

ModelBuildError: Could not build the model: Can't find any valid labels for provided dataset. Labels file

Along with this message next to it:

'Contains invalid label name': Label file

This is showing for all of the files I pulled. I checked the label names, file names, extraction path and all of it tracks perfectly. What is the best way to fix this problem?

Hi @sripadh puligilla,

Thank you for reaching out to Microsoft Q&A forum!

I tried to reproduce the issue you reported and was able to train the model successfully. However, I understand that you are still facing the issue.

The error message indicates a problem with the label file provided for the training dataset. The label file is a JSON file that contains key-value associations entered manually by the user. It is required for labeled data training, but not every source file needs a corresponding label file. Files without labels are treated as regular training documents.

To resolve this issue, you can try the following:

Make sure that the label file is in the correct JSON format and that there are no syntax errors.

Make sure that the label file corresponds to the training dataset. The label file should have the same name as the training document, with the addition of the ".labels.json" extension.

Check the label names in the label file. Make sure that the label names are valid and do not contain any special characters or spaces.

If you are still having issues, try creating a new label file and retrain the model.

See: Document Intelligence custom models.

I hope this helps! Let me know if you have any further questions.
