Rclpy with sudo

I have a Raspberry Pi 3b+ with Ubuntu ARM and ROS2 installed. I have a python package that writes to a topic every two seconds and it works fine when I run it without sudo the thing is that i need to run it as sudo since i have to send messages of my I2C sensor to that topic making SMBUS not work without it. The message that i get is the following: "No module named 'rclpy'"

If possible: try to see whether there is a way to give your current $USER write access to the hw (ie: file in /dev) instead. In most cases sudo is not needed, just access to the device file.

You most likely need to source the setup file after escalating to a new shell with root privileges.

Or use -E perhaps: https://stackoverflow.com/questions/8633461/how-to-keep-environment-variables-when-using-sudo

Sadly the -E on the sudo is giving me the same error. You did you meant with the first thing you said? I'm kind newby to this :/
