Hi 

I'm new to GNU radio and is trying to develop my own block. I want to develop a block that intake a vector and out put sum of the vector elements. I used the out of tree module and followed tutorial using python code. How should be the arguments of blocks.vector_source_f to be given if i am inputting vector stream of four integers is used. the python code and test file is given below. 

Does your intake vectors have fixed-length or variable length?

If they are variable length, then your sream_ff block won't be very useful in graphical GRC flowgraph, because there the vector streams are usually fixed-length.

If they are fixed-length, then your problem could be easily solved; just create sream_ff as a decimator block.
