Rossen Kinov 0

Hi,

I have created a custom Model. However, in the processes of labeling and training it failed with

Model training failure "InvalidContentSourceFormat: Invalid content source: Could not read build content."

and went int a Status failed.

Now I can not delete this model.

Please help with info on how to remove the failed model?

Thank you,

Rossen

Hi Vasavi,

Thanks for the response. I already tried using the REST API to delete the failed models. Unfortunately the delete REST API returns '404 Not Found'.

They are not listed when I call the List Models Rest API.

The only solution for now is to delete the whole project and recreate the models in a new one.

Is there any better way of solving this issue?

Thanks,

Rossen

Hello @Rossen Kinov , Thanks for using Microsoft Q&A Platform.

Sorry to hear about the inconveniences. This is a known issue. Unfortunately, cancelation of model while training is not supported, however you can delete the model using REST API.

Here is the documentation to manually delete the model using REST API: https://westus.dev.cognitive.microsoft.com/docs/services/form-recognizer-api-2023-07-31/operations/DeleteModel

I hope this helps.

Regards,
Vasavi

Hello @Rossen Kinov , sorry to hear that it didn't work in this case. My suggestion is if you are unable to train a new model with different modelID then you can delete the project and map the current storage account with new project so that all the labels and training data will automatically be added.
