When does this happen?
IF Using HuggingFacePipeline from langchain_community.llms.huggingface_pipeline raises a ValueError: 'alternative_import must be a fully qualified module path'.
How others solved it
THEN Either pin langchain-community and langchain-core to version 0.2.1, or migrate to the langchain-huggingface package. The recommended fix is to install langchain-huggingface (e.g., 0.0.2) and update imports: from langchain_huggingface.llms import HuggingFacePipeline.
from langchain_huggingface.llms import HuggingFacePipeline
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
model_id = 'meta-llama/Meta-Llama-3-8B-Instruct'
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)
pipe = pipeline("text-generation", model=model, tokenizer=tokenizer, max_new_tokens=10)
hf = HuggingFacePipeline(pipeline=pipe)Related patterns
