Hey community,
Everytime I close Matlab I will have to re-install the deep learning toolbox in order to be able to load and interpret the convolutional neural networks. I have also noticed that the toolbox's apps are missing in the Apps section but in the add-on sectionI find the deep learning toolbox installed so I have to uninstall and reinstall it!
Thank you so much.
Here's the error:
In main/importSignalMenuSelected (line 769)
In matlab.apps.AppBase>@(source,event)tryCallback(appdesigner.internal.service.AppManagementService.instance(),app,callback,requiresEventData,event) (line 37)
In matlab.ui.internal.controller/WebMenuController/fireActionEvent (line 67)
In matlab.ui.internal.controller/WebMenuController/handleEvent (line 55)
In matlab.ui.internal.controller.WebMenuController>@(varargin)obj.handleEvent(varargin{:}) (line 36)
Undefined function 'classify' for input arguments of type 'uint32'.

Perhaps your preferences directory has become corrupted. Maybe try deleting the preferences directory and restarting MATLAB.
To find the preferences directory, type:
>> prefdir
Delete the folder and then restart MATLAB. This will force MATLAB to regenerate it again.

yes，sir，may be use
type=classify(net.Faridtypeclassifier,mat2gray(X));

Thank you, it doesn't help really. when I try to run:
net=load("test.mat"); %test mat is a convolutional neural network.
I face the following warning:
Warning: Variable 'layers_1' originally saved as a nnet.cnn.layer.Layer cannot be instantiated as an object and will be read in as a uint32.
