George,
I have made several OOT Python blocks with variable numbers of inputs and
outputs and while I could very easily be overlooking something the error does
not, at first glance, appear to be in the code that you have sent out. Can you
send the rest of your yml file (and potentially the rest of the python)? I am
curious if there is something missing in either the templates or parameters
sections of your yml file.

Hello,
I am trying to make a Python OOT block which accepts a stream of 3 inputs
complex valued data and for each single input sample (one on each input line)
the block will output 8 complex samples. For my first cut, I am simply trying
to get the module to work outputting one complex sample (rather than 8). Below
are the essential parts of my program.
1. In the def __init__ (self.), I set the inner method
gr.basic_block.__init__(self, name="my_block_name_py_cc", in_sig =
[numpy.complex64,numpy.complex64, numpy.complex64 ], out_sig =
[numpy.complex64]) # with 3 inputs and one output
2. In the general_work() method for now I set the output to a constant complex
value as follows out_items[0][:] = 1.0+1.0*1j
3. In the *.yml file, the input is set as: inputs: - domain:
stream dtype: complex multiplicity: '3'
The module compiles. However, when I run the QA file, it gives an error stating
something is wrong in File "..........blocks_swig1.py at line 8354.TypeError:
in method 'vector_source_c_make', argument 2 of type 'bool'
I went to the file and the line stated, but I have not seen anything to help me
make corrections. As far as a TypeError of 'bool', I do not see where I would
have made such an error. I have an input parameter in the def __init__(self,
start = True) method, 'start', which comes in as bool, but that is the only
bool variable I am using. The documentation I read for the method states "This
block produces a stream of samples based on an input vector" (which is my goal
if I can get it to work).
I will appreciate any help to get me on the right track.
Regards,George
