Suppress a warning message from importNetworkFromPyTorch function.

Hello,

When I use importNetworkFromPyTorch() function to import a Torch neural network to MATLAB, the function always prints a warning message as below:

Warning: Network was imported as an uninitialized dlnetwork. Before using the network, initialize it with formatted dlarray(s):

% Create sample data for the network input at index 1:
dlX1 = dlarray(<dataArray1>, <missingFormat>);

% Initialize the network with formatted data:
net = initialize(net, dlX1);

I know that I need to initialize the imported network before using it, so I do not want to see the warning every time when I use the function.

However, I could not find any options in the function to suppress the printing.

Is there a way to suppress the printing?

Hi @SHC,

You can suppress specific warning messages in MATLAB by using the warning function with the appropriate message identifier. Here's how you can do it:

• After the warning is issued, you can use the lastwarn function to get the identifier:

[~, MSGID] = lastwarn();

• Use the warning function with the identifier to turn off the specific warning:

warning('off', MSGID);

• For your specific case, you can add these lines after importing the network to suppress the warning:

importNetworkFromPyTorch(...); % Your import function
[~, MSGID] = lastwarn();
warning('off', MSGID);

Refer to the following documentations:

• Suppress Warnings
• How do I turn off a particular warning in MATLAB? - MATLAB Answers - MATLAB Central
• importNetworkFromPyTorch

I hope this helps.
