I get the this error in terminal: <br>> <br>> in __init__<br>> self.wxgui_waterfallsink2_0.set_callback(wxgui_waterfallsink2_0_callback)<br>> File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 54, in __getattr__<br>> return getattr(self._hb, name)<br>> AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'<br>> <br>> I have been getting this error in multiple programs. So what is stopping the program here? There is no Attribute .set_callback obviously. But where is this attribute missing from exactly and how do i put it where it should be? <br>> -- <br>> <a href="http://mail.python.org/mailman/listinfo/python-list">http://mail.python.org/mailman/listinfo/python-list</a><br></div><div>That error means that 'gr_hier_block2_sptr' doesn't have enough information to proceed.</div><div> </div><div>If you look at the top of the defintion (for example, 'def gr_hier_block2_sptr, [attribute], [another attribute]'), that's where you should find .set_callback. If it's not there, you'l just need to add it to the end; if it <em>is</em> there, then the attribute is probably given a different name somewhere else (so you'll just need to find out its new name and update the existing entry).</div> </div></body>
