I am trying to plot the network performance using following code
[net2,tr] = trainNetwork(augimdsTrain,lgraph,options);
hold on
x = 1 : length(tr.ValidationLoss);
y = tr.ValidationLoss;
idx = ~any(isnan(y),1);
plot(x(idx),y(idx),'--k','Marker','.','MarkerSize' ,12);
but got the following error
Unrecognized field name "num_epochs".
Error in plotperform>update_plot (line 258)
numEpochs = tr.num_epochs;
Error in plotperform (line 109)
plotData = update_plot(param,fig,plotData,update_args{:});
my tr variable have
>> tr
tr =
struct with fields:
TrainingLoss: [1×9187 double]
TrainingAccuracy: [1×9187 double]
ValidationLoss: [1×9187 double]
ValidationAccuracy: [1×9187 double]
BaseLearnRate: [1×9187 double]
FinalValidationLoss: 0.0322
FinalValidationAccuracy: 99.6214

PLOTPERF Plot network performance.
the tr get by train not trainNetwork,so may be should plot perf by self,such as use plotroc(targets,outputs)

targets:real label for test data
outputs:predict label for test data

You can select the 'Plots' name value pair of trainingOptions function to 'training-progress' and then train the network. You will be able to see the training plot, and you can export and save that. For more information, you can refer this documentation.
Hope it helps!
