Problem installing Deep Learning Toolbox Importer for Keras Models

I am running Matlab 2021a with Update 4 on a MacBookPro with MacOS 11.4 and all updates installed.

When I try to install the Deep Learning Toolbox Importer for Keras Models, I get the following error:

Install Folder Error

This folder name is invalid. Folder names can contain alphanumeric characters and '-', '_', '.', or '/' only. The destination folder cannot be named "private".

This happens when I click the Install button and also when I download first then install.

One possible cause is that the support package path has a whitespace character somewhere in it. You can view this path with this command in MATLAB:

matlabshared.supportpkg.getSupportPackageRoot

You can set a new path using the command matlabshared.supportpkg.setSupportPackageRoot. For example if we want to set the path to '/Users/<username>/Documents/MATLAB/SupportPackages' where <username> is your Mac user name, we would do the following (we would need to replace <username> with the actual user name):

matlabshared.supportpkg.setSupportPackageRoot('/Users/<username>/Documents/MATLAB/SupportPackages')

We can then use matlabshared.supportpkg.getSupportPackageRoot to confirm the path has been set correctly. After setting a support package path where there are no spaces or other illegal characters, it should be possible to install the support package.
