theres a temporary problem with the uv package (not scvi-tools)  
please add this line, before running the install of scvi\_colab and it will work:

```auto
#A Manual fix to uv issue in Colab, see: https://github.com/astral-sh/uv/issues/12724
import os
os.environ["UV_CONSTRAINT"] = os.environ["UV_BUILD_CONSTRAINT"] = ""

```

Could we add this to the scVI-colab package or does it need to be called outside of it?

Not exactly sure why this doesn’t work for me.

try it after the installation of scvi-colab, and restart your session. (I installed a specific branch here, but try it with just install())

but youre right, it is not working right now (it worked for me yesterday), I guess their on the fix, at least from what I see in the discussion of the issue [Google colab issue · Issue #12724 · astral-sh/uv · GitHub](https://github.com/astral-sh/uv/issues/12724)  
you can still install with  
`!pip install --quiet scvi-tools`

make no sense to add to the package, its not related to scvi-colab, any package will not work with uv in colab now (also numpy…) w/o the fix.

We should then disable uv until Colab fixes it. It’s annoying but more annoying for users to first need to find this issue and then install it correctly.

seems the issue is solved with colab/uv integraion:
