Hi everyone! I used to be a ROS1 user, but recently I switched to ROS2 foxy. I couldn't use Shebang to change the python environment for running my node (Same as what I used to do in ROS1).

Here is the sample shebang code:

#!/home/user/dev_ws/src/test2/dtw/bin/python3
import cv2
def main():
    print('Hi from test2.')

After running this, still it will be run by default ros python env.

FYI, I have created the package by Colcon.

Anyone know how I could address this issue?
