Hi @Tugce,

It appears that you made a mistake while following the steps to create a neural network using the "nntool" application. I suggest you follow the steps again after closing the application and restarting it.

You could also upgrade MATLAB to R2024b. The newer version has significant enhancements in the Deep Learning Toolbox, and the added functionality would be a major advantage since this issue is not reported in MATLAB R2024b due to the removal of the "nntool" function for starting the Neural Network Manager application.

I am unsure about the License Manager error since I have not encountered this error code before, you can refer to this MATLAB answer for more advice on how to troubleshoot License Manager Errors in MATLAB: https://www.mathworks.com/matlabcentral/answers/404028-license-problems-cheat-sheet

To read more about the Deep Learning Toolbox in MATLAB R2024b, refer to the following documentation: https://www.mathworks.com/help/deeplearning/index.html

Unfortunately, my cheat sheet does not list error 942. I am not able to locate error 942 in associatation with any FlexLM license server.

I have noticed that people club error messages when reporting them. For ex: Reporting the message as 742 when the error codes are 7 and 42.

I too could not find the error 942 anywhere so I attached your sheet just in case the OP feels that a error code is relevant to their query.
