Visual Studio (all versions) automatically detects each installed Python interpreter and its environment by checking the registry according to PEP 514 - Python registration in the Windows registry.Python installations are typically found under HKEY_LOCAL_MACHINE\SOFTWARE\Python (32-bit) and HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Python (64-bit), then within nodes for the distribution such as . Install cv_bridge from source cv_bridge, which is part of the ROS perception vision_opencv package, must be compiled with Python 3 enabled. The issue arrises when I started to run the node itself, which gives the following error: Searching online, I found out that others had a similar issue when there are 2 conflicting versions of OpenCV being used. Using OpenCV with ROS is possible using the CvBridge library. Here I ran into multiple issues: 1) I installed opencv, but couldn't import it in python3, the error message was: 2) Then I couldn't import rospy, but installation of python3-catkin-pkg-modules and python3-rospkg-modules fixed that problem.
