成功安装pydot和graphviz运行时还是出现ImportError:Failed to import pydot怎么办？？

Question

因为无法下载pydot1.1.0，就载了个pydotplus，改了一下graphviz.py文件中find_graphviz()函数的代码，然后文件重命名成pydot，修改的代码如下：

   # Method 3 (Windows only)
#

    if os.sys.platform == 'win32':
        # Try and work out the equivalent of "C:\Program Files" on this
        # machine (might be on drive D:, or in a different language)
        #
        if False:  # os.environ.has_key('PROGRAMFILES'):
            # Note, we could also use the win32api to get this
            # information, but win32api may not be installed.
            path = os.path.join(os.environ['PROGRAMFILES'], 'ATT', 'GraphViz', 'bin')
        else:
            # Just in case, try the default...
            path = r"F:\anaconda\bin"

    for path in (
            '/usr/bin', '/usr/local/bin',
            '/opt/bin', '/sw/bin', '/usr/share',
            '/Applications/Graphviz.app/Contents/MacOS/'):
        progs = __find_executables(path)
        if progs is not None:
            # print("Used path")
            return progs
      # Failed to find GraphViz
     # 
    return None

然后检验也确实安装成功了

但是运行程序时还是显示ImportError:Failed to import pydot怎么办？求大佬解决

可能pydot安装的路径不对，可以去调换一下路径或者再刷新几下，有时候我也是这样子弄得。再不行可以用pip安装发
