• sphinx-exercise
• sphinx-tojupyter

@shlff would you have 10 minutes to cast an eye over the generated preview above and let me know if you spot any issues (as a double check). This is a big upgrade to the software so it would be great to get a second opinion on:

• html
• download ipynb
• download pdf

[mmcky]

• check arg\\max and arg\\min rendering in math (html)

[mmcky]

hey @shlff can you let me know if you're planning to review this PR? No worries if you don't have the time. I'll set some time aside next week to review so it can be merged.

[shlff]

Thanks for reminding me of this @mmcky . Actually I reviewed this PR last month but I forgot to update my reports here. I would take time to recall the issues I find and report them to you by next Tuesday (23nd Nov.).

[mmcky]

@shlff I just updated anaconda to the 2021.11 from 2021.05 (which was causing some issues). Hopefully the 2021.11 will be more stable. Looks god so far from my review.

[mmcky]

From my review this morning I think this is looking pretty complete.

[mmcky]

@shlff I am going to merge this so if there are any bugs that you come across let me know and we can issue a fix.

[shlff]

Thanks @mmcky . I quickly went through the HTML and download pdf of the lectures quickly and didn't find any big issues. They look good to me.

I have been reading the HTML and ipynb files of the lectures one by one carefully and I will report in the issue tracker if I spotted any issue.

thanks for the update @shlff that gives me confidence :-).
