Don't you need to instantiate "Receive"? --- Jim Melton
Non-Sensitive From: discuss-gnuradio-bounces+jim.melton=sncorp....@gnu.org <discuss-gnuradio-bounces+jim.melton=sncorp....@gnu.org> On Behalf Of Elmore's Sent: Monday, August 28, 2023 09:15 To: discuss-gnuradio@gnu.org Subject: [EXTERNAL] Selector error - "IndexError: output_index must be < noutputs" I am attempting to use a Selector block with 2 outputs. I want to select the output programmatically. When I run the flowgraph, I get the subject error. The following is my abbreviated code which is pertinent to the question interspersed with explanatory comments: import Receive Receive is a Hier Block which I import in to my Python file blocks_selector_0 = Receive.blocks.selector(gr.sizeof_float*1,0,0) Instantiation of blocks_selector_0. The Selector block is in the Receive Hier Block. blocks_selector_0.set_output_index(0) I am trying to select the 0 output. This is where the error occurs. 0 is certainly less than 2 so what is happening?
