Need to resolve the version dependency conflict first (CC: @dishaprakash ):

INFO: pip is looking at multiple versions of google-cloud-aiplatform[langchain,reasoningengine] to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install -r requirements.txt (line 3), -r requirements.txt (line 5) and google-cloud-aiplatform[langchain,reasoningengine]==1.130.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    langchain-community 0.4.2 depends on langchain-core<2.0.0 and >=1.4.0
    langchain-google-vertexai 2.1.2 depends on langchain-core>=0.3.76
    google-cloud-aiplatform[langchain,reasoningengine] 1.130.0 depends on langchain-core<0.4 and >=0.3; extra == "langchain"

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
