# Create batch file with these commands:
c:\__full_path_to_virtualenv__Scriptsactivate.bat && python __full_path_to_python_script__.py
# && means run command2 if command1 completed successfully.
#Then set that batch file as script to run.
#You don't need to set any additional arguments in task scheduler (or you can set them in batch file anyway)
#and can set Start in if script has to read/write from specific directory and uses relative paths.
