variables are called before they are defined. For example you are referencing ‘new_examples’ in cell 10, while it is only defined in cell 12.
The inability to download the notebook and edit it in a stable environment also adds to frustration and significantly distracts from the course.
Suggestions:
- Test the notebooks. Even just plain “Run all” could suffice before you publish it.
- Do not provide the notebooks.
As it is I am more motivated to vent and look elsewhere than pay attention to what could be useful information.
