Wpf 调用ironpython异常修正

异常内容：

ImportException: “not a Zipfile”

修正方法：

    ScriptSource script;
            ScriptEngine engine;
            engine = Python.CreateEngine();
            engine.Runtime.IO.RedirectToConsole();

            var pc = HostingHelpers.GetLanguageContext(engine) as PythonContext;
            var hooks = pc.SystemState.Get__dict__()["path_hooks"] as List;
            hooks.Clear();

    _cycleScope = engine.CreateScope();

    script = engine.CreateScriptSourceFromFile(AppDomain.CurrentDomain.BaseDirectory。。。。。);

    var result = script.Execute(_cycleScope);

异常内容：KeyError，但功能能够顺利执行

原因：python脚本代码变量为未初始化
