Hi,

If you've recently installed Jupyter-AI and tried interacting with popular providers like OpenAI, Ollama, or others, you may have noticed that a minimal installation(pip install jupyter-ai) is missing some necessary packages.

At this point, you have two options:

• Install the full version with pip install jupyter-ai[all].
• Install the additional package for your chosen provider. E.g. pip install langchain-openai

Unfortunately, running pip install jupyter-ai[all] can result in an infinite installation loop due to pip's dependency resolution, often without success. 😞

`INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime. See https://pip.pypa.io/warnings/backtracking for guidance. If you want to abort this run, press Ctrl + C.

Additionally, installing the individual package for your chosen provider may lead to dependency conflicts, such as the one shown below: 😞

$ pip install langchain-openai
....

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

If you'd prefer to avoid this issue, you can install the packages using Conda: 💡

conda install conda-forge::jupyter-ai conda-forge::langchain-openai

Unfortunately, Conda doesn't include all the available provider packages. E.g. https://anaconda.org/search?q=langchain-ollama

In such cases, you can install older versions of these packages manually, like so:

pip install langchain-openai==0.1.23
pip install langchain-ollama==0.1.0
