When want to use method Start, that is defined for top_block_gui class, i always get this error:
AttributeError: 'gr_top_block_sptr' object has no attribute 'Start' [savi_ne@ts-070046nl GRC]$ gvim /usr/local/lib64/python2.6/site-packages/gnuradio/gr/top_block.py But it is clear that tb is of top_block_gui, and there is no error for using Run method. Why is this so?
