In the past I would enable inline visualization in a qiime2 jupyter notebook with
`jupyter server extension enable --py qiime2 --sys-prefix`
However, in version 2026.4 I get this error:
```auto
Enabling: qiime2
Writing config: /opt/miniforge3/envs/rachis-qiime2-2026.4/etc/jupyter
Validating qiime2...
X Validation failed: The module 'qiime2' could not be found. Are you sure the extension is installed
```
Using `rachis` instead of `qiime2` doesn't change the error. Otherwise the environment is functional and can be used in jupyter without inline visualizations.
Thanks for the feedback

Ok. I now realize there is a new `jupyterlab-rachis` package for visualizations in the modern lab (nice - hope it works in VSCode as well).
The package doesn't appear to be distributed with pip or conda yet. Is that correct?
I installed it manually from github source in a jupyterlab environment
```auto
conda install -c conda-forge nodejs
pip install .
jupyter labextension build .
```
Seems to work and it didn't break any dependencies for that env.
This issue can be closed, but it would be super appreciated if you had a chance to document this extension better in the installation section of rachis. And a conda/mamba release would be super.
Thank you very much.

Hey @Alxdu,
Apologies for the oversight on our part.
I've just uploaded the package to PyPI after fiddling with the CI a bit to get it working.

Alas, I don't think this is possible without an explicit VSCode extension. I'm not entirely sure how that is handled, but I think it's a separate ecosystem as the underlying UI framework is pretty different.

@Alxdu, we have [an issue in our issue tracker](https://github.com/rachis-org/using-qiime2/issues/54) now to get this documented. Thanks for bringing this up!
