To address the issue with installing chroma-hnswlib on macOS, you can try setting the environment variable OBJC_DISABLE_INITIALIZE_FORK_SAFETY to YES. This can help avoid errors during the build process. Here is how you can do it:

  1. Before running the installation command, set the environment variable:

    export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES

  2. Then, proceed with the installation:

    python3 -m pip install langflow

Additionally, you can use Docker as an alternative installation method. Here are the steps:

  1. Clone the LangFlow repository:

    git clone https://github.com/langflow-ai/langflow.git

  2. Navigate to the docker_example directory:

    cd langflow/docker_example

  3. Run the Docker Compose file:

    docker compose up

LangFlow will then be accessible at http://localhost:7860/.

These steps should help you successfully install LangFlow on macOS [1][2].

But the install steps are working in Google colab.

@Knight7561

Just to make sure, are you trying to install it using PIP?

Steps to Install Langflow:

Knight7561 commented 2 months ago

I didn't try conda, but I did using pip and the above error is via pip

NadirJ commented 2 months ago

@Knight7561 which Macbook do you have? I suspect you have a Macbook with a M1,M2 or M3 chip if this is case your hitting an known issue with chroma I suspect ref: https://medium.com/@pxlnkrbbt/in-case-someone-has-a-problem-when-installing-chromadb-ac2b6b536bfc ref2: https://github.com/chroma-core/chroma/issues/221

Can you try setting this in your terminal before running pip export HNSWLIB_NO_NATIVE=1

Knight7561 commented 2 months ago

I am using an Intel based Mac. Is that a compatibility issue ?

Knight7561 commented 2 months ago

Trying out export HNSWLIB_NO_NATIVE=1 and then doing pip install langflow works, with some mismatching dependencies. But, yes does the Job. Thank you @NadirJ @carlosrcoelho for helping out.
