我是一名学生并在GNU Radio工作。
我有一个python代码，我想在GNU无线电伴侣中运行，但我无法搜索正确的块来执行该代码...任何人都可以帮助我吗??当我执行相同的python代码（不在GNU中，我收到以下错误：
AttributeError：＆＃39; top_block_sptr＆＃39;对象没有属性＆＃39; wxgui _＆＃39;
代码如下所示：

中存在错误的换行符
self.wxgui_
waterfallsink2_0 = waterfallsink2.waterfall_sink_c(...
删除错误的换行符，它应该可以正常工作。如果有疑问，请使用GNU Radio Companion重新生成python文件。确保你的编辑不会在他不应该的地方添加换行符。
