how to create a updatable coreml model?

Question

I tried to build a pre-trained core-ml model with the help of create ML framework, but the model created is not updatable, Is there a way to create a pre-trained core-ml model which can be updated on the device itself (newly introduced feature in Core-ML 3) ?

Answer 1

Not directly with Create ML, you'll have to use coremltools to make the model updatable. See here for examples: https://github.com/apple/coremltools/tree/main/examples

However... this will only work for neural networks and k-nearest neighbors models. Create ML does not actually produce these kinds of models (at the moment).

For example, an image classifier trained with Create ML is a GLM on top of a fixed neural network. You cannot make GLM models updatable at this point.

So in short, no, you can't make models trained with Create ML updatable.
