langchain-chroma depends on numpy (>=1.26.2,<2.0.0)

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

def retriever_tool():
    """
    Consult the company policies to check whether certain options are permitted.
    """
    vectorstore = Chroma(
        embedding_function=AzureOpenAIEmbeddings(deployment=os.environ["EMBEDDING_DEPLOYMENT_NAME"], chunk_size=1),
        collection_name="local-rag",
        persist_directory=os.environ["DATA_STORAGE"],
        client_settings=Settings(anonymized_telemetry=False, is_persistent=True),
    )
    retriever = vectorstore.as_retriever(search_type="similarity", search_kwargs={"k": 3})
    return create_retriever_tool(
        retriever,
        "docs_retriever",
        "Get information about pcfc roles and responsibilities policy and regulations",
    )

Error Message and Stack Trace (if applicable)

No response

Description

The current version of langchain-chroma (0.2.2) specifies a dependency on numpy>=1.26.2,<2.0.0. This constraint conflicts with other packages that require numpy>=2.0.0 or higher, causing version resolution failures in projects that depend on both. For example, a project using langchain-chroma (>=0.2.2,<0.3.0) alongside another package needing a newer numpy version cannot resolve dependencies. Could the upper bound on numpy be relaxed to >=2.0.2 in a future release to improve compatibility?

Could langchain-chroma be updated in a future release to support numpy>=2.0.2, given the current restriction to <2.0.0 causes conflicts with packages needing newer numpy versions?

Hi @ahenawy,

Thanks for the report - yes, I'm working on a fix in #30714 :)

Ah actually, going to close this as a dupe of #29467, but we'll still fix via the above PR :)
