Hello James:
I am using the mainline GNU Radio 3.7.12, and the embedded Python block does support vector inputs (although I was not able to figure out how to change the length during the execution). Ubuntu 16.04 bundles an older version of GNU Radio, so you may want to install a custom-built GNU Radio. Upgrading the Ubuntu distribution may also work. (I know 18.04 is due very soon - I do not know what version or GNU Radio is bundled, however.)

I found this thread from 2016: https://lists.gnu.org/archive/html/discuss-gnuradio/2016-10/msg00087.html
that discusses the issue I am having, but when I tried to reply to the thread I got a responding email that said my email didn't go through. The thread discusses how support for vector input / output wasn't included in the Embedded Python Block and I was wondering if this was something that was ever, or will ever be, added to the GRC mainline? The thread includes a link (https://github.com/skoslowski/gnuradio/tree/epy_vectors) from Sebastian where he says that if you try that version it should have the added vlen support, but I didn't build gnuradio from source on my computer, I installed via "sudo apt install gnuradio". Basically if I define my embedded python block to have vector input and output in the python code... i.e. in_sig = [(np.complex64, 128)], out_sig = [(np.complex64, 128)] then I get this error: Param - Code(_source_code): Invalid conversion specification But the same code works fine in an OOT module (assuming the proper xml code too). Is there an extra step that I am missing when using vector input/output and the embedded python block? Or is this an issue other people have had?
