I am trying to add a new feature to Isaac Sim’s HelloWorld: get a camera image, and want to use YoloV5 to do object detection on the captured image. However, when I added yoloV5 project files to HelloWorld folder, I reported an error when loading yoloV5 related modules in HelloWorld. Is there a solution?
Hi @845004988
You can install any python package by following the step, to install additional packages, described in the Isaac Sim doc: 4. Python Environment Installation — Omniverse Robotics documentation
Also, you can use the omni.kit.pipapi extension to install the required package at run time
try:
import yolov5
except ImportError:
omni.kit.pipapi.install("yolov5")
import yolov5

thank you,it really helpful!
Hi. I got a similar problem when tried to import a package named Pinocchio. I followed the instructions in Python Environment Installation: open a terminal directly at the Isaac Sim root folder and use pip to install the package:
./python.sh -m pip install pin
where pin is the package name which is implied by Pinocchio installation instructions (Pinocchio Installation Procedure).
Then I tried to import the pinocchio package (import pinocchio) in the script editor or in the example extension
HelloWorld, and the console gave a no module found error:
