problems with mybinder requirements.txt

[thomasfermi]

Hi everyone,

I somehow can't get interactivity via Thebe/Binder to work. I followed the ínstructions in "Launch buttons for interactivity". It did not say where to put the requirements.txt, so I checked how it was done in https://github.com/executablebooks/jupyter-book. I mimicked that for my repo, but when I click the Binder link in my jupyter book on this section it takes me to a "non-working" Binder: When I execute the notebook it says that the numpy import failed.

Can someone tell me what I am doing wrong? Is it something obvious? If not, is something wrong with my ipynb file? Maybe the metadata or something?

Regarding the requirements.txt: I do my actual requirements managing with conda, that is why there is an environment.yml file in the "book" folder (for github actions workflow). For Binder I do not need all the stuff from my conda environment: pytorch is in my environment.yml, but the section where I want "Thebe"-interactivity on my web page only needs numpy+matplotlib. That is why I just copied the content of the requirements.txt from the docs folder of the jupyter-book repo .

I would be really grateful for some help :)

P.S.: I really love jupyter book. Keep up the great work :)!

hi @thomasfermi -- do you know if your repository builds directly with mybinder.org? The jupyter-book binder setup is contained in .binder at the root level of the repository. It looks like you have put requirements.txt in books and I don' think binder would find it in that location.

If you haven't tried this -- I would start there to see if the project is building by adding in the link to your repository, branch etc. and then click on launch. https://mybinder.readthedocs.io/en/latest/introduction.html#build-your-repository

Please let me know how you go.

Hi @mmcky and thanks a lot for your help! Putting the requirements.txt into a .binder directory at root level fixed my problem. I even found that it works with an environment.yml instead of a requirements.txt. I ran into a new problem however:

• In this section of my book I can launch "Binder" and it works: I get plots and I can manipulate the plots with ipywidgets sliders
• If I launch "Live Code" instead of "Binder" it doesn't work as expected: Plots get generated but the ipywidgets sliders disappear as soon as I click "run" in the corresponding cell.

Am I missing something, or should I file this as a bug report for Thebe?

P.S.: I am glad that you like the repo! Thanks :-)

Update: I've been browsing github and it seems that interact does not work in Thebe, and it is a known issue. I will have to wait until this gets fixed.

Thanks again for the help @mmcky :-)

thanks for the update @thomasfermi -- I am glad you're up and running (half-way at least). Thanks for linking that thebe issue here.
