Why python debugger always get this timeout waiting for response on 113 when using Pycharm?

Question

Bigger image

Especially I run code perhaps running a little long time(10 mins roughly), and hit the break point. The python debugger always show me this kind of error "timeout waiting for response on 113" I circle them in red in screencut.

And I use Pycharm as my python IDE, is it just issue for Pycharm IDE? Or Python debugger issue? And if Pycharm is not recommended, can anyone give me better IDE which be able to debug efficiently.

I had a similar thing happen to me a few months ago, it turned out I had a really slow operation within a __repr__() for a variable I had on the stack. When PyCharm hits a breakpoint it grabs all of the variables in the current scope and calls __repr__ on them. Here's an amusement that demonstrates this issue:

import time

class Foo(object):

    def __repr__(self):
        time.sleep(100)
        return "look at me"

if __name__ == '__main__':
    a = Foo()
    print "set your breakpoint here"

PyCharm will also call __getattribute__('__class__'). If you have a __getattribute__ that's misbehaving that could trip you up as well.

This may not be what's happening to you but perhaps worth considering.
