Re: [Discuss-gnuradio] Fatal Python error: PyThreadState_Get: no current thread (OSX 10.10.5, Homebrew install)

[Michael Dickens]

Hi David - It looks from the 'brew install log that brew is using "/usr/local/Cellar/python/2.7.10_2/bin/python", while you're trying to use "/usr/local/bin/python". These may or not be the same install of Python; given the PyThreadState_Get error you're getting I'd bet they are different versions. Would you be willing to do a quick test? Look at < https://github.com/gnuradio/gnuradio/pull/604/files > and follow the very small change they recommend. You'll need to uninstall gnuradio first, then make the change, then install it. It very well might take care of your issue & would also help me out in the process by testing this change. I've been busy with dealing with 10.11 & some issues it has created with my laptop (crashes & such; not fun ones either). If you can't try this for any reason that's OK too; just throwing it out there. Hope this helps & thanks! - MLD

I’m trying to get gnuradio working with my RTLSDR.  When I get a fresh install of gnuradio from homebrew, it seems to install OK, but when when I try to run the companion it dies with the error:

 

Fatal Python error: PyThreadState_Get: no current thread

Abort trap: 6

 

I’ve done some research and this seems to have something to do with system Python vs. Homebrew Python, but I’ve done which python and it gives me /usr/local/bin/python.  Not sure where to go from here without just installing macports, so any advice would be appreciated!
