Use your Predibase models with Langchain.
To use, you should have the predibase python package installed,
and have your Predibase API key.
The model parameter is the Predibase "serverless" base_model ID
(see https://docs.predibase.com/user-guide/inference/models for the catalog).
An optional adapter_id parameter is the Predibase ID or HuggingFace ID of a
fine-tuned LLM adapter, whose base model is the model parameter; the
fine-tuned adapter must be compatible with its base model;
otherwise, an error is raised. If the fine-tuned adapter is hosted at Predibase,
then adapter_version in the adapter repository must be specified.
An optional predibase_sdk_version parameter defaults to latest SDK version.
