The version compiled and installed on the E310 is 3.8.0.0. As I stated in my last mail, I tried to compile my OOT module forcing cmake to use python 2.7 (see https://pastebin.com/EZfNkcGy), but it did not solve the problem. An other question, why the same version of gnuradio (3.8.0.0) I compiled and installed on my host machine uses python 3, and on the E310 uses python 2?
