Segmentation Fault (core dumped) in Python 2 and Python 3

[RubensZimbres]

I was successfully able to run a customized hotword.py notebook in Ubuntu 16.04 and also in a Raspberry Pi3, where I added:

if event.type == EventType.ON_RECOGNIZING_SPEECH_FINISHED:  
    if event.args['text'].lower()=='suspend':  
        print('Speech Recognized')  
        os.system('systemctl suspend')  

However, at home in my other Ubuntu 16.04, I get the following output:

device-model-id home-ABC12345
device_id: ABCDE12345

Fatal Python error: Segmentation fault

Previously, I had the same problem - Segmentation fault (core dumped) with Spyder, that would only open with a specific PyQt5 version.

However, it is quite complex to map / try all dependencies of google-assistant and their versions for compatibility. It seems it depends upon the version of libraries installed, for instance, with Anaconda.

Here are my libraries from pip list -l:

Arpeggio (1.9.0)
asn1crypto (0.24.0)
cachetools (3.1.0)
certifi (2018.11.29)
cffi (1.12.1)

setuptools (40.8.0)
six (1.12.0)
sounddevice (0.3.12)
tenacity (4.12.0)
urllib3 (1.24.1)

For Python 3 I get:

device-model-id home-ABC12345
device_id: ABCDE12345

Any suggestions ? ulimit adjustment didn't solve the problem. I can run 'systemctl suspend' and 'reboot' using voice, but when I try 'scrot' it aborts.

UPDATE:

I did a fix: instead of running

    if event.args['text'].lower()=='screenshot':
        print(event.args['text'])
        print('Speech Recognized')
        import os 
        os.system('scrot')

I created another Python notebook containing:

import os
os.system('scrot')

And then altered hotword.py to:

    if event.args['text'].lower()=='screenshot':
        print(event.args['text'])
        print('Speech Recognized')
        import os 
        os.system('python3 scrot.py')

No problem now.
