RWKV language models.
To use, you should have the rwkv python package installed, the
pre-trained model file, and the model's config information.
Example:
.. code-block:: python
from langchain_community.llms import RWKV model = RWKV(model="./models/rwkv-3b-fp16.bin", strategy="cpu fp32")
response = model.invoke("Once upon a time, ")
