how to run deep learning project with raspberry pi 4 modelB

im practicing files with link: https://kr.mathworks.com/matlabcentral/fileexchange/68474-deep-learning-for-defect-detection-on-raspberry-pi?s_tid=srchtitle

but i don't know how to solve this error.

and when i saw this website i can actually understand how should i do.

: https://kr.mathworks.com/help/coder/ug/prerequisites-for-deep-learning-with-matlab-coder.html

this is my installed add-ons.

<< error code>>

Deploying code. This may take a few minutes.

Hi,

It appears that OpenCV and ARM Compute libraries are not installed on your hardware. To resolve this, you can follow these steps using the hardware setup screen.

• Go to Home tab -> click on Add-Ons dropdown
• Select Manage Add-Ons
• Search for MATLAB Support Package for Raspberry Pi Hardware
• Click on the gear icon at then end
• Follow the screens
• Select "Yes" from Install ARM Compute Library screen
• Select "Yes" from Install OpenCV Library screen

Refer to the following link to know more,

hi thank you for your answer!!

but after i followed steps you suggested, i can't still run these code.

is there i have to do about " environment variables"??
