class EmbeddingRequired

Documentation

Raised when an embedding is requested but cannot be produced.

Two situations: no embed_fn has been configured on the Storage, or the node has no text content to embed.

Example:

>>> from mnemosine import Storage, EmbeddingRequired
>>> with Storage(":memory:") as db:
...     doc = db.node(kind="doc")
...     doc.save()
...     try:
...         doc.add_embedding()
...     except EmbeddingRequired:
...         print("set storage.embed_fn first")
set storage.embed_fn first
