HI, I had installed GNU Radio recently and tried to execute a simple example as shown in the image below. But it throws me the following error. I referred various sources and I came to a guessing conclusion that this would be an issue with installation. But I am sure, everything went right during installing. I am not able to figure out what and where it went wrong. Kindly help! Error: Traceback (most recent call last): File "/home/vishnu/top_block.py", line 85, in <module> tb = top_block() File "/home/vishnu/top_block.py", line 48, in __init__ self.top_layout.addWidget(self._qtgui_freq_sink_x_0_win) File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/top_block.py", line 100, in __getattr__ return getattr(self._tb, name) AttributeError: 'top_block_sptr' object has no attribute 'top_layout' <http://gnuradio.4.n7.nabble.com/file/n44755/flow_g... Is the error due to the GUI component as I don't get the error when I execute other simple example using audio source, throttle and a audio sink. Could anyone give me an idea where would be the issue? -- View this message in context: http://gnuradio.4.n7.nabble.com/AttributeError-whi...

It's likely that you have the "Generate Options" in the "Options" block set wrong (probably to WX GUI) while you are trying to use a QTGUI sink. Change that option to "QT GUI" and you should be fine.
