Request Module Import Failing Topic is solved

[Luxtux]

Good afternoon,

I'm trying to use python instead of lua in my latest automation script; so i can learn python. The entire example given when you select python is already generating errors. after some googling i figured out that the wrong module is imported. Now im trying to import the request module but eventough its installed on the system, domoticz keeps giving the error below.

Code: Select all

 2021-03-10 15:24:29.584 Error: EventSystem: Failed to execute python event script "Python Test"
2021-03-10 15:24:29.584 Error: EventSystem: Traceback (most recent call last):
2021-03-10 15:24:29.584 Error: EventSystem: File "<string>", line 5, in <module>
2021-03-10 15:24:29.584 Error: EventSystem: ModuleNotFoundError: No module named 'requests' 

when i check the system it clearly states that requests is installed:

Code: Select all

>sudo pip3 list

the simple code im trying to execute is

Code: Select all

import DomoticzEvents as DEVS
from datetime import datetime
import requests as REQ


HueIP = '192.168.100.50'
HueUsername = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

for name, value in DEVS.user_variables.items():
    if name == 'AlarmTime' :
        #DEVS.Log("Python: User-variable '{0}' has value: {1}".format(name, value))
        ts = int(value)
        test = datetime.utcfromtimestamp(ts).strftime('%Y-%m-%dT%H:%M:%SZ')
        DEVS.Log(test)
        response = REQ.get("http://"+ HueIP +"/api/"+ HueUsername +"/schedules")
        
        DEVS.Log(response.status_code)
 

The server is a debian 10 x64 VM with python version 3.7.3 and Domoticz V2020.2 (build 13051).

Any suggestions?

Is your domoticz also running as root?

Is your domoticz also running as root?

No of course not. when i run the pip3 list command as the Domoticz user, i get the same list as when i run it as root.

This might explain it. when i print out the paths used by python in domoticz its different from the command line.
These are the on the python command line as domoticz user :

Code: Select all

['', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/home/domoticz/.local/lib/python3.7/site-packages', '/usr/local/lib/python3.7/dist-packages', '/usr/lib/python3/dist-packages']

and this is the result in domoticz:

Code: Select all

2021-03-10 19:05:49.469 /opt/domoticz/scripts/python/
2021-03-10 19:05:49.469 /usr/lib/python37.zip
2021-03-10 19:05:49.469 /usr/lib/python3.7
2021-03-10 19:05:49.469 /usr/lib/python3.7/lib-dynload

this is how i fixed the issue for future reference.

Code: Select all

import DomoticzEvents as DEVS
from datetime import datetime

if '/home/domoticz/.local/lib/python3.7/site-packages' not in sys.path :
    DEVS.Log('Path not found')
    sys.path.append( '/home/domoticz/.local/lib/python3.7/site-packages' )
else:
    DEVS.Log('Pathfound')

import requests

Thanks Luxtux for your solution.
I have been struggling for long with this issue.
I had to adapt the path to the settings on my system, but got it working.
