how to detect programmatically spyder debug run

[joo0ne]

I need to programmatically detect that the code is running in debug mode. Something like #ifdef DEBUG in C. This is needed for additional code that will improve debugging. For example, for CUDA, you need to set the environment variable CUDA_LAUNCH_BLOCKING=1 , etc.

I have already checked the advice from the Internet (+AI):

• pdb._getframe().f_back is not None - does not work;

• os.getenv('SPYDER_DEBUG_MODE') - does not work;

• 'ipdb' in sys.modules - does not work.

Hey @joo0ne, thanks for reporting. This should do the trick:

from IPython import get_ipython

shell = get_ipython()
shell.is_debugging()

That's True when Spyder is in debugging mode, False otherwise.

Let us know if that works for you.

Unfortunately it doesn't work for me. But I found a solution on SO that works:

import sys

gettrace = getattr(sys, 'gettrace', None)

if gettrace and gettrace():
    print('Debug')
else:
    print("No debugger")
