Many thanks @mmcky,
I was about to open an issue on this. The same error also appears in:
amss.md
amss2.md
amss3.md
as I am testing the migrated lecture.
They appeared in:

and are related to this deprecation warning before:
/tmp/ipykernel_11213/2711255625.py:130: DeprecationWarning: setting an array element with a sequence. This was supported in some cases where the elements are arrays with a single element. For example `np.array([1, np.array([2])], dtype=int)`. In the future this will raise the same ValueError as `np.array([1, [2]], dtype=int)`.
Thanks @HumphreyYang feel free to jump in and take ownership of the issue if you know how to fix them.
Many thanks @mmcky and @Smit-create,
I worked on this when I was building the lecture, so I will take ownership of this issue : )
There is a reported execution error in
opt_tax_recur.md
in this cell
