"No module named 'torch'" using crontab

My Python code works fine if I run it from the command line by:

 $ python3 detect_people_main.py

Now I want to run the code from crontab using:

@reboot sleep 30 && /usr/bin/python3 /home/pip/Downloads/yolov7/detect_people_main.py >> /home/pip/Downloads/yolov7/logfile.log 2>&1 &

while printing the logs in logfile.log. But the code does not work from crontab. And the log is :

Traceback (most recent call last):
  File "/home/pip/Downloads/yolov7/detect_people_main.py", line 6, in <module>
    import torch
ModuleNotFoundError: No module named 'torch'

I am using Jetson NANO to run the code. Any suggestions to solve the issue?

Solution

  • I was running the code on reboot using crontab from the sudo user. Somehow my Python from sudo user could not find Pytorch. After switching from sudo crontab -e to only crontab -e I solved the issue for Pytorch.
