Hi Nemanja!
None is an object of type NoneType; thus, the output signature list has length 1; it should have length 0.
Use out_sig=[] instead.
Greetings,
Marcus

NemanjaThis is a bit frustrating situation, and I don't know how to solve the problem. I tried to figure out what's going on, and wanted to call function input_signature () from python i norder to see what is the actual output signature but this function can't be called. I also couldn't find right explanatoin for port problem.Any suggestions?

I am sorry, the subject of previous post is wrong cause I solved that problem meanwhile, but I forgot to change it in the draft.

It looks that my 3.6.4git versio doesn't support message passing logic within python, so I switched to another pc where I run 3.7.0. I assume that because there is no function for registering message ports, but when I changed to 3.7.0, there was no that error any more.Hi all,this thread is more or less extension of the thread: http://gnuradio.4.n7.nabble.com/3-6-4-2-test-fail-tc43452.html
No the problem is the following:
the block is very simple:
def __init__(self):
gr.sync_block.__init__(self,
name="msg_sender",
in_sig=[numpy.int8],
out_sig=[None])
self.message_port_register_out(pmt.pmt_intern('out_port'))
but when i run flowgraph, the following error comes out:
RuntimeError: msg_sender(2): insufficient connected output ports (1 needed, 0 connected)
From where came that output that I havent declared?
