Dear all,
while creating an app using app designer I am not able to compeltelly deploy my trainned CNN. My main issue is wiht the function classify which should be valid with:
[YPred]= classify(app.net,app.imds1);
Where app.net is the trainned CNN, app.imds1 is the imageDatastore where all the images that I want to classify are stored.
The error message that I got is:
Error using classify (line 123)
Requires at least three arguments.
Meaning that the function classify is using a 2nd options instead of the one that I want it to use. Is there a way to make it work? Could it be that I did not completelly unistall Matlab 2018b from my computer? I have 2019a running but it never occurred this error before...
