'from langchain.vectorstores import Chroma' could not find Chroma

[ljhust]

following doc below: https://langchain.readthedocs.io/en/latest/modules/utils/combine_docs_examples/vectorstores.html from langchain.vectorstores import ElasticVectorSearch, Pinecone, Weaviate, FAISS, Qdrant, Chroma could not find Chroma, as ref to the source code Chroma module has been delayed, please modify the doc correctly

As a workaround, this seems to work:

from langchain.vectorstores.chroma import Chroma

Not sure why __init__ is not exposing Chroma, as it appears to be imported correctly.

It is my version: lanchain==0.0.84 and source below there is no Chroma included

should be fixed now

This error seems to still be present for me

did you try to bump langchain in your requirements.txt, or take version constraint away and then: pip install langchain --upgrade

Installing collected packages: langchain
  Attempting uninstall: langchain

update langchain version

can someone help me

i get this error

this is my code:

fromlangchain.vectorstores import Chroma

....

vectorstore = Chroma.from_texts(texts, embeddings)
...

After a long workaround i solved the issue like this. override chromadb with pysqlite3-binary Please note that this is applicable for linux only . In window i used python 3.11.5 to solve the issue.

1. install pysqlite3-binary pip install pysqlite3-binary

2. Add this in your project code where importing chroma

from langchain.vectorstores.chroma import Chroma sys.modules['sqlite3'] = import('pysqlite3')
