시작 시 Python 스크립트를 실행할 수 없습니다. 라즈베리 파이 4

부팅할 때 Raspberry pi 4에서 Python 스크립트를 실행하려고 합니다. 이 Python 스크립트를 직접 실행하면 오류 없이 작동합니다. 다음과 같이 crontab 파일을 편집했습니다.

# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
@reboot python /home/pi/FUZEGUI.py > /home/pi/FUZEGUIlog.txt

로그 파일에 정보가 없습니다. 나는 다른 접근 방식을 시도했습니다 rc.local.

# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi
printf "Launching FUZE GUI"
sudo python home/pi/FUZEGUI.py &
exit 0

하지만 그것도 작동하지 않습니다. 스크립트
