Installation Error

[suywang]

When I used pip to install cactus, I met a severe error:

The conflict is caused by:
cactus-llm 0.3.3 depends on langchain>=0.2.1
langchain-community 0.3.1 depends on langchain<0.4.0 and >=0.3.1
cactus-llm 0.3.3 depends on langchain>=0.2.1
langchain-community 0.3.0 depends on langchain<0.4.0 and >=0.3.0

So can you help me solve this error? Thanks!

Sure, let me see if I can track down the issue.

Could you provide information on the system you are trying to install on? Primarily the OS and version of python you are using.

And are you getting the error while running the pip install git+https://github.com/pnnl/cactus.git command?

Thank you! My OS is Ubuntu 24.04.1 LTS, with 6.8.0-45-generic. My python version is 3.12.
I create a new conda env before I use "pip install git+https://github.com/pnnl/cactus.git".
The error is :

ERROR: Cannot install cactus-llm and cactus-llm==0.3.3 because these package versions have conflicting dependencies.

The conflict is caused by:
cactus-llm 0.3.3 depends on langchain>=0.2.1
langchain-community 0.3.3 depends on langchain<0.4.0 and >=0.3.4
cactus-llm 0.3.3 depends on langchain>=0.2.1
langchain-community 0.3.2 depends on langchain<0.4.0 and >=0.3.3
cactus-llm 0.3.3 depends on langchain>=0.2.1
langchain-community 0.3.1 depends on langchain<0.4.0 and >=0.3.1
cactus-llm 0.3.3 depends on langchain>=0.2.1
langchain-community 0.3.0 depends on langchain<0.4.0 and >=0.3.0

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
