Re: [GNU Radio 3.8] Error loading modules on E310

[Ivan Iudice]

Hi Philip!
I only have site-package folder in both python2.7 and python3.5 lib folders, no 
dist-package.
The problem is that in python3.5/site-package there is not numpy, it’s only in 
python2.7/site-package.
Is it not installed for python3? How can I install it in both the sdk sysroot 
and in the target?
Thanks so much.

Ivan
