|The version compiled and installed on the E310 is 220.127.116.11.|
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 (18.104.22.168) I compiled and installed on my host machine uses python 3, and on the E310 uses python 2?

What version gnuradio is installed on the E310?$ gnuradio-config-info -vThere should be a cmake variable to set the python interpreter version.That might be better than trying to point at libraries in the sdk.Try -DPYTHON_EXECUTABLE=python (or path to python in the sdk)PhilipOn 2/21/20 11:54 AM, Ivan Iudice wrote:

I tried configuring as in:
Cmake said that 3.5 is required, but finished configuring; anyway I compiled and installed, but nothing changed.

gnuradio-companion calls the interpreter
Thus, the first python in the path is Python 2.7.
Is gnuradio using python 2.7?
Yes, try convincing cmake to use python2 for your OOT.

$ less `which gnuradio-companion`
And see which python interpreter gnuradio-companion uses. Hopefully
someone from Ettus support knows for sure and can help with the OOT.
Your OOT looks like it is using python3

Your help is very welcome!
I’m sorry for the stupid question, however, how can I know which version of python is used by gnuradio?

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?
hmm, is gnuradio on the e310 using python 2 or 3? Maybe mixed python
Sorry for the short answer, trying to help, but I don't use the Ettus
builds for gnuradio.
Thanks so much.

I had some dist-packages versus site-packages with some versions of
gnuradio. See if both exist. I'm betting numpy is in site-packages.

This is a problem that, obviously, everybody wants execute custom module could incur.

finally I cross-compiled my OOT module for running on USRP E310.
Based on the instructions at "https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source", I set the environment variable PYTHONPATH a little bit different, to point the path of the installed OOT module:
Such a way, on the target I can load my custom module in python.
root@ni-e31x-316AFEA:~# python3 -c "import custom_mod"
I created a flowgraph that use my OOT module, and I discovered in the newer file system for E310 python3 has not all of the needed libraries.

How could I solve the problem?
I'm so close to run my OOT modules on the target...
Thanks so much.
