VertexAiRagRetrieval needs llama-index package

[julienvincendeau-rc]

Hello,
I test an example with RAG https://github.com/google/adk-samples/blob/main/python/agents/RAG/rag/agent.py

When I launched it, it's failed because I need to install https://pypi.org/project/llama-index/

I'm a little surprised and embarrassed because our security team doesn't validate Meta's AI, only GCP's via Vertex.
I currently use https://pypi.org/project/google-adk/

Thank you for your help

it's in extra dependency: https://github.com/google/adk-python/blob/main/pyproject.toml#L126 . Maybe adk-samples can try to fix it.

The original post refers to llama-index package not being installed. But, it seems llama-index has already been added to pyproject.toml.

I also did a clean installation for this sample in a newly created pyenv environment and used poetry install to install the packages. A quick pip freeze shows the following packages are installed:

...
llama-cloud==0.1.35
llama-cloud-services==0.6.54
llama-index==0.12.52
llama-index-agent-openai==0.4.12
llama-index-cli==0.4.4
llama-index-core==0.12.52.post1
llama-index-embeddings-openai==0.3.1
llama-index-indices-managed-llama-cloud==0.8.0
llama-index-instrumentation==0.4.0
llama-index-llms-openai==0.4.7
llama-index-multi-modal-llms-openai==0.5.3
llama-index-program-openai==0.3.2
llama-index-question-gen-openai==0.3.1
llama-index-readers-file==0.4.11
llama-index-readers-llama-parse==0.4.0
llama-index-workflows==1.3.0
llama-parse==0.6.54
...

However, hangfei's comment refers to another line and package:

  "crewai[tools];python_version>='3.10'", # For CrewaiTool

Does it mean crewai[tools] needs to be added to pyproject.toml?
