Deep learning toolbox keeps disappearing

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/handleEvent (line 55)

In matlab.ui.internal.controller.WebMenuController>@(varargin)obj.handleEvent(varargin{:}) (line 36)

Undefined function 'classify' for input arguments of type 'uint32'.

Error in main/importSignalMenuSelected (line 770)

Error while evaluating Menu Callback.

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.

Thank you so much David,

Did that, I will keep you updated on the result.

@David yes it actually did!

Answer 2

[yanqi liu]

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.
