Question

Hi,

I used the above v3.0 api and payload to train a model without labels but i am getting this error message
"Could not build the model: Can't find any OCR files for training." from the api in header["operation-location"] key

It is working with v2.1 api.

@Sharma, Manish Thanks for the question. Please follow the below document for Custom neural models that are only available in the v3 API.
