Mybinder.org and repo2docker updates

Binder
1

Some updates to BinderHub and repo2docker have been deployed to mybinder.org, which folks may notice:

  • Python 3.10 is now the default Python version, for repos that don’t specify a python version
  • Jupyter Server is the default server implementation instead of jupyter-notebook
  • ‘too-old’ Python handling, where we put the kernel in a separate env, now applies to Python <= 3.6, where it used to apply only to Python 2.7.

Let us know if you encounter any issues and we’ll try to work them out!

I think I have encountered an issue related to this update. I have a Jupyter Notebook that used to launch directly into appmode when accessed using the following link:

https://mybinder.org/v2/gh/olivertlord/hydrous-melts/main?urlpath=apps/hydrous_melt_PVTX.ipynb

Now, that link produces the following error:

404 : Not Found You are requesting a page that does not exist!

A workaround detailed here apparently solved this issue, but is now also broken, potentially by this update.

Below is a log produced by running

less ~/.jupyter-server-log.txt

in the terminal accessed from the notebook by altering the above url after appmode launch failure.

Any suggestions for how to get around this issue would be greatly appreciated.

It looks like there’s a recently merged (but not yet released) PR with some jupyter-server fixes for appmode:

I just discovered mybinder recently, but I experience issues with installing dependencies using a requirements.yml file. It’s in the root directory of the repository, but it seems to be completely ignored when building the docker image. I’ve tested the file with a conda env create -f requirements.yml locally, and it works well. Can this be an issue related to the update?

Here’s a great tip: give your YAML file the correct name :slight_smile:

For pip installation: requirements.txt
For conda installation: environment.yml (not requirements.yml)

I can confirm that the above seems to work nicely with the new update!
