Unable to run on ubuntu server

[LuisDiazUgena]

Hi!

I'm developing a bot to run this PID-Analzyer (I've been using the bot on my w10 computer without no problems at all). Now, I want to run it on an Ubuntu server result of uname -a:

uname -a
Linux ubuntu 5.3.0-1008-raspi2 #9-Ubuntu SMP Fri Oct 18 13:26:35 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux

I've followed the instructions on issue #44 and i'm facing some problems to run it. If I type:

python3 PID-Analyzer.py --blackbox_decode ./blackbox_decode -l /home/ubuntu/bots/plasmatreebot/downloadDir/539011/btfl_004.bbl

the output is:

as you can see, it says "Killed" after start analizing pitch ...

I've found that using:

import matplotlib 
matplotlib.use('Agg') 

removes from previous :

Unable to init server: Could not connect: Connection refused

This problem was not related with the script itself, it was something about the hardware I run on it. There wasn't enough cpu power and ram available and it killed the process
