Dear Vipin, I believe I came across the issue recently. But I m not sure if that is the exact issue.
I was using Numpy SWIG in my OOT, so that when I convert from C++ to Python, I got a Numpy complex numbers. My reason of using Numpy was mainly continuous buffer support but probably getting complex number support was a side product. So, I don't have solution to exactly what's your issue but here <https://github.com/kartikp1995/gr-bokehgui/blob/develop/swig/bokehgui_swig.i> is my SWIG file. It would be great if you can share a minimal example or provide the link to public repo so that I can debug on my end. Thanks!
