Issue #, if available:
Description of changes:
ModelBuilderfor model customization is too broad; it assumes everyModelPackageis a JumpStart fine-tuned model with abase_modelreference. This fails for use cases where you might have trained/fine-tuned a model using a 1P image or custom container with no direct link to a base model.I've included a
base_modelcheck so that_fetch_and_cache_recipe_config()is only called when abase_modelexists.By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice.
