I’d like to use the countdown service to run a Python script to collect some data and other functions.
I understand that commands such as ‘quantrocket history collect’ can be executed by Crontab. However, for more complex workflows, I believe it’s better to use Python for this task, and reserve Crontab for pure scheduling.
Running my Python script ‘get_listings.py’ from JupyterLab works fine.
I’ve tried running the same script using Crontab with the following command:
* * * * * python /codeload/data/scripts/get_listings.py
However, I get an ImportError: ‘No module named quantrocket.master’.
I understand that when Python scripts are executed from JupyterLab the environment on my machine is /opt/conda/lib/python3.6, which also has the required site-packages /opt/conda/lib/python3.6/quantrocket/master.py, etc.
I assume when Crontab executes python that it is calling on the system’s default python, which wouldn’t include the quantrocket package.
How do I get Crontab to tell my machine to use ‘quantrocket’ Python?
