Trying to create an llm via HuggingFaceHub() but get "coroutine 'AsyncRunManager.on_text' was never awaited'

Trying to create an llm via HuggingFaceHub() but get "coroutine 'AsyncRunManager.on_text' was never awaited'

[whitead]

Try setting key_filter = False when you run query

[maspotts]

Thanks: tried it but got same error. Is this (specifying a HuggingFaceHub() model) expected to work? Or am I trying something that's not officially supported? I'm not yet familiar enough with langchain to know whether what I'm trying to do makes sense!

[whitead]

The "error" you're showing is just a warning. Are you sure there is not another exception?

[maspotts]

Ah, good point: I may have jumped the gun! I had assumed something had gone fatally wrong because the process hangs after emitting the warning. I've started it again and left it running; will see if it's completed or errored out or still hanging in the morning...

OK here's the final exception (actually two exceptions?):

NotImplementedError: Async generation not implemented for this LLM.

[whitead]

Looks like the model timed out @maspotts - the open source models are a lot slower and paper-qa requires a lot of calls. I would recommend Claude or HuggingFace with a GPU instance if you're look to replace the OpenAI models. Llama can work too, but it's extremely slow

[maspotts]

Thanks: (off-topic but) do I need to upgrade to a paid huggingface tier to get sufficient performance?

[whitead]

Not sure, I have paid huggingface and I'm not sure what is available on free tier
