cv2.error: OpenCV(4.5.0) /opt/opencv/modules/dnn/src/cuda4dnn/csl/memory.hpp:54: error: (-217:Gpu API call) initialization error in function 'ManagedPtr'

I am using ros2 - galactic docker with jetson nano, and i'm trying to run a simple script that uses OpenCV

ros2 nodes are running fine except when using cv2. what I did so far, is to remove cuda 11-4 and link cuda from jetpack(10-4) to the docker. but when I did this, this error occurs somehow.

import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/dist-packages/cv2/__init__.py", line 96, in <module>
    bootstrap()
  File "/usr/local/lib/python3.8/dist-packages/cv2/__init__.py", line 86, in bootstrap
    import cv2
ImportError: libcublas.so.11: cannot open shared object file: No such file or directory

is someone already resolved this issue? thanks in advance!

these are the flags I am using to run the docker --rm \ -it \ --runtime nvidia \ --network host \ --gpus all \ --privileged \ -e DISPLAY \ -v /dev/bus/usb/:/dev/bus/usb/ \ -v /usr/local/cuda-10.2/:/usr/local/cuda-10.2/ \ -v /usr/lib/python3.6/dist-packages/cv2/python-3.6/:/usr/lib/python3.6/dist-packages/cv2/python-3.6/ \ but no to avail. the docker still uses cuda 11-4 and python3.8 but when i remove the cuda 11-4 and python3.8, ROS2 is not working anymore.

but no to avail. the docker still uses cuda 11-4 and python3.8 but when i remove the cuda 11-4 and python3.8, ROS2 is not working anymore.

Hi @foxydevelby, which container are you running? Since you are on Nano, it should be one of the JetPack 4 ones for r32.7.1, like dustynv/ros:galactic-desktop-l4t-r32.7.1

but no to avail. the docker still uses cuda 11-4 and python3.8 but when i remove the cuda 11-4 and python3.8, ROS2 is not working anymore.

Thanks @dusty-nv! this is the one I am using dustynv/ros:galactic-ros-core-l4t-r35.3.1, let me try that one and let you know after I tested

Hi @dusty-nv, I have successfully installed this image, however I am getting opencv version compatibility issue when running again my simple object detection script

net.setPreferableBackend(cv2.dnn.DNN_BACKEND_CUDA) AttributeError: module 'cv2.dnn' has no attribute 'DNN_BACKEND_CUDA' can you help me confirm if using opencv really works with the galactic docker image in jetson nano?

Hi @foxydevelby, what does cv2.getBuildInformation() report for you? This is what it looks like for me in dustynv/ros:galactic-desktop-l4t-r32.7.1

python3 -c 'import cv2; print(cv2.getBuildInformation())'

  -----------------------------------------------------------------

I just used the built -in cuda 10.2 and python3.6 from the jetpack,looking at your report, did you build the newer version of opencv with cuda?

@foxydevelby, you aren't using the OpenCV that was built with CUDA - are you sure you are running in dustynv/ros:galactic-desktop-l4t-r32.7.1 ? If you start a fresh container of this, it should be there. Do sudo docker pull dustynv/ros:galactic-desktop-l4t-r32.7.1 to pull the latest too.

Maybe you installed something else in the container, which overwrote the OpenCV. In that case, you can reinstall OpenCV/CUDA like this:

cd /opt && ./opencv_install.sh

thank you @dusty-nv ! re-installing worked!
