Hydra does not work with pdb #1237
Description
🐛 Bug
Description
When running pdb as in
python -m pdb myscript.py
the debugger does not allow me to inspect local variables upon exception.
To reproduce
# myscript.py
import hydra
@hydra.main()
def app(cfg) -> None:
x = 0
assert False
if __name__ == "__main__":
app()Run:
❯ python -m pdb -c continue myscript.py
Traceback (most recent call last):
File "/Users/ethanbrooks/ppo/myscript.py", line 8, in app
assert False
AssertionError
Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.
The program exited via sys.exit(). Exit status: 1
> /Users/ethanbrooks/ppo/myscript.py(2)<module>()
-> import hydra
(Pdb)
At the prompt, type p x
(Pdb) p x
*** NameError: name 'x' is not defined
Expected Behavior
pdb should work as it does when not using hydra:
def app() -> None:
x = 0
assert False
if __name__ == "__main__":
app()❯ python -m pdb -c continue myscript.py
Traceback (most recent call last):
