Re: memory errors in 3.8.2

2020-09-06 Thread Ron Economos


A few notes:

1) The automatic update may be bad. The GNU Radio PPA has other 
procedural problems and this may be another.


2) Your OOT may be over-writing some Python code. I've seen this before. 
The different error behavior depends on exactly where your code got 
loaded in memory.


3) Believe it or not, the module destructor never gets called in GNU Radio.

R: R: Cannot run a command

2020-09-06 Thread Vincenzo Mone

Apologies Chris,

you said to run the 2to3 command on all the scripts that get called from 
mun_downlink_proxy.py.  

Please can you tell me all the scripts that I have to run the command or how to 
do to know

Which one are?

Thanks for your collaboration and understanding

This is correct for we are converting your scripts to use python3.  I recommend

Hi Vincenzo,

 

No problem on the help.  You should say you are not good in Linux yet. :)  I'll 
try to explain as best I can.  The import commands you are trying to run in the 
terminal need to be interpreted by python.  So you would open a terminal and 
type python3, then hit enter and then try to import the module.  What you have 
attempted to do is have the bash shell interpret python commands, which it 
won't do.  Your python script you are trying to get running has a line in it 
import urllib2.  This module existed in python2, but has been renamed in 
python3.  My best advice is to run 2to3, which is a program to convert python 
scripts from python2 to python3, on your

Theses are Python commands. When you open a terminal window, you are at a bash 
shell that only accepts bash commands. 

 

At the bash prompt, try typing python3. 

This should start python and leave you at a python prompt. THEN type the python 
commands.
