Key idea

Task Scheduler runs your script in a different environment than your terminal.

Be explicit about:

• Python executable path
• script path
• working directory

Practical advice

• Use a .bat.bat file that activates venv then runs the script
• Log output to a file

Example batch file

@echo off
cd /d C:\path\to\project
C:\path\to\venv\Scripts\python.exe my_script.py --source C:\data

@echo off
cd /d C:\path\to\project
C:\path\to\venv\Scripts\python.exe my_script.py --source C:\data
