Re: [Discuss-gnuradio] GL sinks freeze

[Josh Blum]

I put the fix on a branch "fix/waterfall" at http://gnuradio.org/git/jblum.git

I also wonder why it did not throw an error: one of the calling methods must have a try/except block, but I couldn't find it.

I put my own try/except in to print out the error. Its seems that the more recent implementation of numpy.choose only handles lookups into tables that are between size 2 and 32.

Thanks Josh -- ended up finding the same thing right around the same time. =) Wonder why Python wouldn't print the error message to stderr. The diff fixes the problem for me as well. I'll take a look at switching back to using numpy.choose, although the for loop seems to work fine for now.
