Binder discuss

Hello,

We are recently getting this error in mybinder:

Error removing intermediate container 94c744059fac: No such container: 94c744059faceee7c5bbba589dd4536af8bd040ba183be78fba10186f70a8a93
unknown parent image ID sha256:adef09a9712d9c35c587a139adf4f40e3616fa05f41cdb668d7276cf5b360158

mybinder link: Binder

I couldn’t find a similar issue reported over here.

Could you please point us where to start troubleshooting?

Many thanks,
Sebastian

It looks like you’re downloading some large files, and unzipping them which will be even larger. Does the build succeed if you omit those files?

Many thanks @manics

Indeed, it works:

and after accessing JupyterLab, I could execute the remaining steps in postBuild:

# download data
zenodo_get -r 6366659

#unzip HCG_VLA_HI_data_products.zip
unzip GBT_spectra.zip
unzip optical_images.zip
unzip HCG_VLA_HI_mom1_maps.zip

Do we need to ask the end user to manually execute these steps after getting into JLab? or is there a way to automate this?

Best regards,
Sebastian

You could perhaps try adding a start file?

Thanks @manics

It didn’t like it:

Spawn failed: Server at http://<>/ didn't respond in 30 seconds

This should reproduce the issue.

Also, reading the docs:

This script is executed each time your binder is started and should at most take a few seconds to run.

I also found:

After all, maybe the best option is to perform the download into the notebook…

Thanks!

Hi again,

Should conda-lock be part of the default environment in mybinder?

Currently testing:

https://github.com/conda-incubator/conda-lock/issues/285#issuecomment-1324743002

In:

https://mybinder.org/v2/gh/AMIGA-IAA/hcg_global_hi_analysis/binder

Thanks!

conda-lock isn’t included, however mamba has support for installing from lock files:

Thanks @manics!

Using micromamba worked!

I think it’d be a good idea to add conda-lock to your binder dependencies anyway, in case the underlying package manager changes in future (it used to be conda, then was changed to mambaforge because it was a lot faster).
