Update ipython and ipykernel versions in environment.yml - #29
Merged
Conversation
The older versions ran each notebook cell in a cleared context, which resets numpy 2 print options for cell. The problem surfaced when using datascience and numpy packages in the same notebook. The clearing of context cleared datascience's np.set_printoptions(legacy='1.13') which set up numpy to start using it's latest print options (e.g. np.True_) and consequently broke our tests when we use otter grade. The newer versions no longer reset per-cell, so datascience's legacy setting persists and notebook output matches what autograder seeds expect and consequently CI will match the grading servers behavior
