I am using 'importKerasNetwork' to import my keras models for next step in MATLAB. However, I have tens of thousands of small models.

Can I have an approach to save the loaded variables (SeriesNetwork objects) to a file like .mat, so that I could load those models faster?

I have tried to save the workspace directly. But MATLAB 'save' seems only support variables in 'double' style.

Any ideas? Thank you for any help!

Absolutely I can import them every time when I need. But it takes me about 20 mins. I just wondering whether there is a faster way or not.

在 MATLAB Online 中打开

yes，sir，may be use save to get mat file for target variable，such as

warning off all

modelfile = 'digitsDAGnet.h5';

net = importKerasNetwork(modelfile)

net =

DAGNetwork with properties: Layers: [13×1 nnet.cnn.layer.Layer] Connections: [13×2 table] InputNames: {'input_1'} OutputNames: {'ClassificationLayer_activation_1'}

save('net_for_load.mat', 'net')

d2 = load('net_for_load.mat');

d2.net

ans =

DAGNetwork with properties: Layers: [13×1 nnet.cnn.layer.Layer] Connections: [13×2 table] InputNames: {'input_1'} OutputNames: {'ClassificationLayer_activation_1'}
