python runtime warning debugging
Question:
I am trying to learn Python, and I am still a novice so please bear with me. I am using the Komodo IDE environment. I currently wish to debug a a runtime warning that says:
RuntimeWarning: invalid value encountered in greater & (matrixCsvOutput[:,8] > 30))[0] ,:]
Now, I wish to set a breakpoint that would allow me to examine the composition of “matrixCsvOutput” at runtime. I expect that the value in question may be a null or a nan, and therefore fail the operation.
My question is: how can I set the debugger to break when the runtime error occurs? Many thanks in advance!
Answers:
before the line number mentioned in RuntimeWarning, add this:
import pdb ; pdb.set_trace()
You can run your script through pdb from the command line too:
python -m pdb myscript.py
(command taken from the pdb docs)
To anyone (but probably not novice) who concerns only debugging the runtime warnings, you may find this post helpful.
