Hi all; I received below message when i try to open deep learning app, i have nonproblem with my lice and alrady bought deep learing tool box.
Error using deepNetworkDesigner
Invalid default value for property 'Network' in class 'deepapp.internal.editor.import.NoArgsCallStrategy':

You can check what toolboxes are on your license by checking your MathWorks Account. Click on your license number to view the products included on your license.
If you see that you do have a license for the Deep Learning Toolbox, I would suggest using the Add-Ons Explorer to uninstall the Deep Learning Toolbox. Once uninstalled, restart MATLAB and use the Add-Ons Explorer to add the Deep Learning Toolbox.
If that doesn't work, I suggest contacting support.

Try this. Tell us what you see in the command window:
% Check that user has the specified Toolbox installed and licensed.
% hasLicenseForToolbox = license('test', 'image_toolbox'); % Check for Image Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Image_Acquisition_Toolbox'); % Check for Image Acquisition Toolbox.
% hasLicenseForToolbox = license('test', 'Statistics_Toolbox'); % Check for Statistics and Machine Learning Toolbox.
% hasLicenseForToolbox = license('test', 'Signal_Toolbox'); % Check for Signal Processing Toolbox.
% hasLicenseForToolbox = license('test', 'Video_and_Image_Blockset'); % Check for Computer Vision System Toolbox.
hasLicenseForToolbox = license('test', 'Neural_Network_Toolbox'); % Check for Deep Learning Toolbox.
if ~hasLicenseForToolbox
% User does not have the toolbox installed, OR if it is installed, there is no available license for it.
% For example, there is a pool of 10 licenses and all 10 have been checked out by other people already.
ver % List what toolboxes the user has licenses available for.
message = sprintf('Sorry, but you do not seem to have the Deep Learning Toolbox.\nDo you want to try to continue anyway?');
reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes');
if strcmpi(reply, 'No')
% User said No, so exit.
return;
end
else
fprintf('You do have a license for that toolbox.\n')
end

Try again later. I could be wrong but it looks like you have it installed but don't have a license to use it. One possibility is that you're using some kind of shared license and there is just a limited number of licenses available at any point in time, and you just were unlucky enough to pick a time when all the licenses were "checked out" by other students. When one of them exits MATLAB, that should free up a license.
If you are not using a shared license, the call tech support for free installation help, even for students. But you'll have to wait until Monday. Maybe you could just try reinstalling.

It appears that you're encountering an error when trying to open a Deep Learning app, specifically the "deepNetworkDesigner" in MATLAB. The error message indicates that the issue is related to the "layerGraph" and mentions that it requires a Neural Network Toolbox license.
Here's what you can do to address this issue:
  1. License Verification: Make sure that your Neural Network Toolbox license is correctly installed and activated. Sometimes, licenses can become inactive or expire, causing such errors.
  2. MATLAB Version Compatibility: Ensure that your version of MATLAB is compatible with the Neural Network Toolbox. Some functionalities might require a specific MATLAB version or update.
  3. Reinstallation: If you've recently updated MATLAB or the Neural Network Toolbox, consider reinstalling or updating the toolbox to ensure that you have the latest version that's compatible with your MATLAB installation.
  4. License Manager: Check your MATLAB License Manager to confirm the status of your licenses. If you have a valid license but it's not recognized, you may need to reconfigure the license settings.
  5. Support: If the issue persists, it might be beneficial to contact MathWorks support. They can provide you with specific guidance and solutions tailored to your setup and license.
Keep in mind that software-related issues like this can be specific to your setup, so contacting MathWorks support or referring to their documentation for your particular MATLAB version may be the best course of action.
