FallbackRefusedError#

exception scikitplot.corpus.FallbackRefusedError[source]#

A fallback was needed and allow_fallback=False refused it (R2-5).

Raised when the dense backend (or an Annoy binding) cannot run as configured: an installed backend fails to load under "auto", a preferred binding cannot load, or the running binding cannot honour a requested option. It is a RuntimeError, so it is never mistaken for the invalid-data ValueError that disables a dense index.

Annotation:

Unrecognized objtype: exception
