Description
The stack traceback of some errors is displayed incorrectly. Below are two examples of an incorrect stacktrace and correct stacktrace. The incorrect one creates a pandas dataframe in a faulty manner, raising an exception, its stacktrace points to a command in the finally block instead of the pandas dataframe creation which is the actual issue.
The correct example shows how a non-existing key of a dictionary is called, its stacktrace does not point to a statement in the finally block but rather points to the line that actually causes the issue.
Some things i've tried or noticed:
- the correct example contains hyperlinks to each code-line, while the incorrect one doesn't, maybe this is a hint to the cause. I therefore included the stacktrace of both examples in raw text as well as html.
- running the'incorrect stacktrace' example in pure python (.py file) results in a correct stacktrace
- this issue occurs when hosting jupyter notebooks locally, but also in VSCode notebooks using the ipykernel
- Thinking that C-code extensions of Python could be a potential source, I also tried raising errors using torch (torch.tensor('invalid_type') but this results in a correct stacktrace.
- aside of torch i also tried incorrectly initiating classes with other packages, this also lead to a correct stacktrace
