Docker build is missing langchain packages

[azertylr]

Describe the bug
Hello,
When building the docker image, some langchain packages are missing. At least langchain-google-genai and langchain-mistralai

To Reproduce
Run with the following docker file:

services:
  gpt-researcher:
    build: https://github.com/assafelovic/gpt-researcher.git
    environment: 
      GOOGLE_API_KEY: 
      LOGGING_LEVEL: INFO
      FAST_LLM: "google_genai:gemini-1.5-flash"
      SMART_LLM: "google_genai:gemini-1.5-pro"
      STRATEGIC_LLM: "google_genai:gemini-1.5-pro"
      EMBEDDING: "google_genai:models/text-embedding-004"
    volumes:
      - /home/docker/gptr/my-docs:/usr/src/app/my-docs:rw
      - /home/docker/gptr/outputs:/usr/src/app/outputs:rw
      - /home/docker/gptr/logs:/usr/src/app/logs:rw
    restart: always
    ports:
      - 8000:8000

There is an error, saying langchain_google_genai is missing.

Running pip install langchain_google_genai in the container solves the problem.

Additional context

Docker engine: 27.5.1
Host: ubuntu 24.04

Welcome @azertylr,

This is intentional. The motivation is to keep the base GPTR container as light as possible.

Our recommendation is to add your LLM-specific dependencies to the requirements.txt file

May the force be with you 🙏

Thanks for your reply!
Maybe you could update the docker help? https://docs.gptr.dev/docs/gpt-researcher/getting-started/getting-started-with-docker

Sup @azertylr

Happy to get your name into the Git tree if you'd like to update that doc

You can use something similar to what we used here in supported-llms, specifically, the line: "Please note that you'll need to install the relevant langchain package for each LLM" and link to that doc from the docker doc

May the force be with you 🙏
