What happened?

HF now requires you to manually confirm if you want to download and run some custom code. Sometimes it asks for prompts but sometimes just throws an error.

Are there known steps to reproduce?

use HF embedding function with nomic-ai/nomic-embed-text-v1 embedding model. It should throw:

    raise ValueError(
ValueError: The repository for nomic-ai/nomic-embed-text-v1 contains custom code which must be executed to correctly load the model. You can inspect the repository content at https://hf.co/nomic-ai/nomic-embed-text-v1.
Please pass the argument `trust_remote_code=True` to allow custom code to be run.
