My code using semanticseg does not work in AppDesigner with GPU environment.

Hello guys, I have an issue with semanticseg function in AppDesigner.

I wanna inference an image with pre-trained fully-convolutional network in AppDesigner.

But, strangely, the function 'semanticseg' does not work when it's run in AppDesigner with GPU environment

while working well in normal Matlab script environment. And It also works well if run in AppDesigner with CPU.

There is no error message related to GPU but an error message showing up like this:

Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 309)

Error while evaluating Button PrivateButtonPushedFcn.

Is there any solution for this error??

I am using Matlab 2018a, GTX 1070 ti.

If any more information about my computing environment is needed, please leave a comment below.
