Hello Raj, Bugs are tracked on the GitHub Issues system. https://github.com/gnuradio/gnuradio/issues
Looking at the build guide there is no mention of scipy so that should get updated as needed. Also the pybombs recipes do not install scipy by default for GNU Radio. Given that scipy isn't needed for the functionality, only the test, it may be nice to try and remove that dependency from the tests. Thanks for the report!
