Taking a notebook from colab and saving it to github results in an invalid notebook error. Last year github launched rich diffs for jupyter notebooks. I recommend opening the notebooks using colab instead.
getting "unable to render code block" error for preview page of ipynb
When i open it on github, all the cells display.
Basically this is an issue of github, and we cannot fix it in the extension context.
Unable to render code block. We are pleased to announce that, starting today, and as announced on the github blog, jupyter/ipython notebook (.ipynb) files will render directly on github. When i launch jupyter notebooks on jupiter lab, code cells sometimes don’t render. The markdown cells from jupyter notebook.
I am having a conversion issue when trying to view.pynb files i have pushed to github. The bug happens because the code blocks from colab are missing outputs':. They look crooked as if there is some sort of rendering issue. For example, i tried to work with this notebook.
