How to add additional files while creating a MATLAB standalone Application?

Hi i am working in image classification by using Predesigned Deep Learning Architecture Like VGG16,VGG19....etc.i have saved the deeplearning Model in ONNX(Open Neural Network Exchange) format. i have designed an GUI in Matlab for this Classification. In this GUI these ONNX files work well for classification . But while i created a standalone application by using Application Compiler this classification GUI is not working properly even though i have included the support package for ONNX files while packaging. Hereby i am attaching the error thrown away by the software while packaging.the error thrown by MATLAB software are shown below

Compiler version: 8.2 (R2021a)

Hi @Venkatesh Kumar V,

I understand that you are using a predefined DL architecture and trying to save it in ONNX format using a standalone application.

The warnings that you are facing during compilation are because the "exportONNXNetwork" function used to determine support package root in C:\ProgramData\MATLAB\SupportPackages\R2021a\toolbox\nnet\supportpackages\onnx\+nnet\+internal\+cnn\+onnx\+util\addSpkgBinPath.m is not supported for deployment.

As a workaround, please try the following:

1. Update the file addSpkgBinPath.m by replacing line 7 with

if isempty(pathSet) && ~isdeployed

This makes sure the function "matlabshared.supportpkg.getSupportPackageRoot " is not called when deployed.

2. Use the following command to create the executable.

>> mcc -m Testdeeplearning.mlapp -a C:\ProgramData\MATLAB\SupportPackages\R2021a\toolbox\nnet\supportpackages\onnx -a C:\ProgramData\MATLAB\SupportPackages\R2021a\resources\nnet_cnn_onnx  -a C:\ProgramData\MATLAB\SupportPackages\R2021a\bin\win64 

Kindly refer to below documentation to know more about managing support packages:

I hope this helps resolve the issue!
