I have a websocket stream which I want to save data from in a
.csv file. The code works fine, but since my goal is to have it run 24/7, I am implementing the method described on the Long Running Tasks help page.
However, I get an error when the scheduled task tries to run my script. The log says that the error came from trying to
So I wrote a simple script to try to try to find out what is going wrong. The code is below. It simply saves the current time to a
.csv file every 15 seconds. Using the code in the Long Running Tasks help page, I have a scheduled task which attempts to run
saveTime() from the
timeprint.py file once an hour.
import csv import time import websocket # runs fine when this line is commented out def saveTime(): while True: with open('longprint.csv', 'a') as myFile: csv.writer(myFile, delimiter = ',').writerow([int(time.time())]) time.sleep(15)
I first tried running it with line 3 (
import websocket) commented out. It ran without any problems for roughly a day. Then, when I tried running it without commenting out line 3, I get the following error in the scheduled task log...
Traceback (most recent call last): File "/home/arbiter/myScheduledTask.py", line 5, in <module> from timeprint import saveTime File "/home/arbiter/timeprint.py", line 3, in <module> import websocket ImportError: No module named websocket
In short: the code which my scheduled task is attempting to run cannot import a module. Does anyone have any ideas on to why this might be happening?
