What ways I have to debug functions? #804
Description
Currently I have some implementation of order_func_nb for example:
@njit
def order_func_nb(c):
"""Called for each timestamp to generate orders"""
# print(f"Context: {c}") - I want to debug it with print or other ways
return vbt.portfolio.enums.NoOrder
And I tried to use:
- Plain approach with print and I got this traceback:
TypingError: Failed in nopython mode pipeline (step: nopython frontend)

What is the best approach here to make normal debugging with print or other tools?
