Thanks. This should be working. I ran into it the other day and wonder if Colab has changed something. Ideally, we would use anywidget to send the data but servir
is a quick workaround to expose a background webserver to the client. However, as you are noticing, there are more issues that arise with this due to a need to separately configure the web sever for different environments. "easy" locally, and a nightmare for "remote" Jupyter/Colab.
If we used the Jupyter websocket (via anywidget), we could reuse this channel for better consistency across all environments.

oops, just added. Thanks for pointing this out!
For context, Google Colab (historically) has used a Service Worker in the front end to authenticate and proxy HTTP requests to http://localhost
in the google notebook to the backend kernel. This behavior is not documented and I'm guessing there is some change.
Update: I'm able to get servir
working by starting the Provider on host=0.0.0.0
but then the URL provided to the front-end needs to be localhost
to hook into the Service Worker behavior. Here's a hacky workaround, but range-requests don't seem to be working.
!pip install --quiet pygv
!wget https://raw.githubusercontent.com/sehilyi/gemini-datasets/master/data/UCSC.HG38.Human.CytoBandIdeogram.bed
import pygv
pygv._api._PROVIDER.start(host="0.0.0.0") # start background server on `0.0.0.0` instead of `localhost`
pygv.ref("hg38")
pygv.locus("chr1")
track = pygv.track("UCSC.HG38.Human.CytoBandIdeogram.bed")
track.url = track.url.replace("0.0.0.0", "localhost") # change URL given by servir to `localhost` for front end 🙄
pygv.browse(track)

excellent, thanks for checking that out! I am really curious what something like https://github.com/manzt/pygv/issues/1 could look as well...
Hello:) It is great to see this project.
I was trying to see if it worked on Google Colab but it seemed to give an error screenshot
is this expected? i was interested in the servir code cause that worked seemlessly locally in the jupyter lab notebook
