pudb error, ipdb and pdb no error.

Question

I am switching tool-chains, from an eclipse based python ide to a vim based equivalent.

I am currently experimenting with pudb.

I am trying to step through some code google gives as examples for tensorflow. It runs in a venv, on python3.5. None of the debuggers gives a problem on importing venv specific libraries, so I believe they are all operating in the intended venv.

pdb and ipdb both run/step through the code in its entirety without a problem - which is great.

When I try to run pudb I get the following error:

Traceback (most recent call last): 
File "~/interpreters/p35/lib/python3.5/site-packages/tensorflow/python/platform/app.py",
line 44, in run
_sys.exit(main(_sys.argv[:1] + flags_passthrough)) TypeError: main() takes 0 positional arguments but 1 was given

The main is defined as follows:

def main(argv=None):  # pylint: disable=unused-argument    
   cifar10.maybe_download_and_extract()      
   if tf.gfile.Exists(FLAGS.train_dir):
     tf.gfile.DeleteRecursively(FLAGS.train_dir)
     tf.gfile.MakeDirs(FLAGS.train_dir)   
     train()


if __name__ == '__main__':   tf.app.run()

And tf.app.run() looks like this:

def run(main=None, argv=None):
   #Runs the program with an optional 'main' function and 'argv' list.
   f = flags.FLAGS
   # Extract the args from the optional `argv` list.
   args = argv[1:] if argv else None
   # Parse the known flags from that list, or from the command line otherwise.
   # pylint: disable=protected-access
   flags_passthrough = f._parse_flags(args=args)
   # pylint: enable=protected-access
   main = main or _sys.modules['__main__'].main
   # Call the main function, passing through any arguments to the final program.
   _sys.exit(main(_sys.argv[:1] + flags_passthrough))

I was really hoping to get pudb working on this code as I really like its interface.

I fidgeted with a alot of options here and am running up short. Anyone have any ideas about the variance here in operation between pdb, ipdb and pudb?

Thanks,
