Export training-progress plots

I am using Matlab on a remote system. I use the -nodesktop flag and interact via command line.

I use trainnet to train deep learning networks. I would like to save and export the training-progress plots for viewing on a local system. Is this possible and if so, how do I do it?

Thank you.

Hey Matthew,

For exporting the training-progress plots generated on a remote MATLAB machine, you can do the following:

• Save the plots using MATLAB on the remote machine itself. You may find the plot and save it programmatically. To get a better idea, have a look at the below mentioned code snippet from this MATLAB Answer post: https://www.mathworks.com/matlabcentral/answers/831163-save-finalized-training-progress-plots-using-outputfcn

        currentfig = findall(groot, 'Tag', 'NNET_CNN_TRAININGPLOT_UIFIGURE');
        savefig(currentfig,'test.fig');        

• Alternatively, use a custom plot function in the "trainingOptions", or save the plot manually as specified in the following documentation: https://www.mathworks.com/help/deeplearning/ref/trainingoptions.html#bvniuj4
• For exporting a copy of the file to your local system, you can transfer the file using scp commad. For instance,the following command would transfer the plot figure to your local system:

        scp username@remote_host:/path/to/training_progress.png /local/path/

• You may find other file transfer utilities for your usage in the following documentation: https://www.mathworks.com/help/cloudcenter/ug/transfer-data-with-standard-utilities.html

I hope this was helpful!

What is the groot tag? Is that a placeholder?
