There is a problem that it cannot run in python3. #44

Open Choikyungho9 opened 3 years ago

Choikyungho9 commented 3 years ago

python simple_test.py works fine when I run it as terminal on jetpack 4.4.

But python3 simple_test.py in terminal doesn't work.

The error 'Unable to open camera' is displayed.

Please let me know what the problem is. Why does it only work with Python 2 version?

I need to use python 3.6.9 version / opencv 4.5.1.

Which version are you running? I've been unable to recreate this.

thanks for replying but I have solved it.

there are issues with OpenCV. in python3 I have installed the OpenCV - 4.4.5 and in python2 I have been using the pre-installed OpenCV - 4.1.1 in jetson nano os so it is working well with python2 but can not able to open the pipeline by using OpenCV-4.4.5.

So I was checking the OpenCV versions and found the solution. then just simply removed the OpenCV-4.5.5 from python3. and now working very well.

I have never doubted the @jetsonhacks codes It always runs in like one attempt. no west of time. my bad🤗

I rebuilt OpenCV-python with CUDA support with version 4.5.5. However, only python2 can run and python3 can't. Is that version difference the main problem?
