带有 pycharm 的 pycallgraph 不起作用 [英] pycallgraph with pycharm does not work

问题描述

我正在使用 mac os x 并尝试设置 pycallgraph.
我已经用 pip 安装了 pycallgraph，用 homebrew 安装了 graphviz.
一切都从外壳工作.但不是来自pycharm.

I'm using mac os x and trying to setup pycallgraph.
Ive installed pycallgraph with pip and graphviz with homebrew.
Everything works from shell. But not from pycharm.

from pycallgraph import PyCallGraph
from pycallgraph import Config
from pycallgraph import GlobbingFilter
from pycallgraph.output import GraphvizOutput


config = Config()
config.trace_filter = GlobbingFilter(exclude=[
     'pycallgraph.*',
])

graphviz = GraphvizOutput(output_file='filter_exclude.png')

with PyCallGraph(output=graphviz, config=config):
    def my_fun(): 
        print "HELLO"
    my_fun()
