Model Personalization for Digit Classifier Application

[Ashok-Kumar-dharanikota]

Hello Everyone,

I want to implement on-device training for the digit Recognition App. I don't understand how to customize the Model Personalization for the digits training and inference. I would like to add images from the gallery and use that images to train the model. I would like to continuously train and improve the model in mobile.

I am getting some run time issues, can anyone help me to resolve this? Please

Hi @Ashok-Kumar-dharanikota , I think you should open an issue on this repo or just a question in stackoverflow, the Pull Request usually is used to improve or fix a bug in the current repo, but you are changing the model and the code based on your needs and this most likely will be rejected. In your case I would suggest the option I mentioned above (an issue or a question in stackoverflow) and probably you can get help faster in that way.
