vanna version issue

[ilyas032019]

🐞 Bug Report: vanna[anthropic,fastapi] installs vanna 0.1.0 instead of 2.x

Describe the bug
When installing Vanna via:

pip install "vanna[anthropic,fastapi]"

it installs vanna v0.1.0, despite the website documentation recommending this command for Vanna 2.x. As a result, many modules from Vanna 2 (e.g., vanna.base, vanna.servers.fastapi) are missing or broken.

To Reproduce
Steps to reproduce the behavior:

1. In a clean Python environment, run:

   pip install "vanna[anthropic,fastapi]"

2. After installation, run:

   python -c "import vanna; print(vanna.__version__)"

3. Observe that the version printed is 0.1.0.

Expected behavior
I expect the pip install "vanna[anthropic,fastapi]" command (as documented on the vanna.ai website) to install a 2.x version of Vanna, not 0.1.0.

Error logs / Screenshots
No stack trace is needed here because the issue is purely version mismatch — but here is the relevant output:

pip show vanna
Name: vanna  
Version: 0.1.0  
...  
python -c "import vanna; print(vanna.__version__)"  
0.1.0  

Desktop (please complete the following information):

• OS: e.g. Ubuntu 22.04 (or whatever you're using)
• Python: 3.11.x
• Vanna: after install 0.1.0
• pip: (whatever version)

Additional context

• According to the [Vanna GitHub README](https://github.com/vanna-ai/vanna), the proper installation for v2 (in development) is:

  pip install --force-reinstall --no-cache-dir 'vanna[flask,anthropic] @ git+https://github.com/vanna-ai/vanna.git@v2'

• The PyPI page [vanna 2.0.0rc1](https://pypi.org/project/vanna/2.0.0rc1/) shows a release, but the stable vanna[extras] installation path appears to still resolve to 0.1.0.

Suggested fix

• Update the PyPI metadata for vanna 2.x to correctly support extras like anthropic and fastapi, so that pip install "vanna[anthropic,fastapi]" resolves to 2.x.
• Alternatively, update the documentation to reflect the correct installation command for v2 (e.g., using GitHub URL) — or mark stable 2.x on PyPI.

Additionally, there's already a somewhat related issue here: “Dependency Versioning #236” ([GitHub]2) — you could reference that or request to reopen/triage specifically for this extras versioning bug.

If you like, I can generate a correctly-formatted GitHub issue (Markdown) for you — ready to paste into the Vanna GitHub. Do you want me to do that?

Hey @ilyas032019 -- could you double check the Python version you have installed? Please run

python --version

The only reason that pip install would install such an old version of vanna (0.1.0) is because you have an extremely old version of python installed (likely 3.7)

i tried in 3.11 and 3.12

What do you get when you run this:

pip --version

You should see something like -- this will definitively tell you the Python version that pip is using.

pip 24.1.2 from /usr/local/lib/python3.12/dist-packages/pip (python 3.12)
