hi dude thanks for your reply! I have viewed the example of this one to save model: https://github.com/lochenchou/Caffe2Projects/blob/master/src/mnist_save_load_example.py 73
I guess I may use f.write(model.net 3._net.SerializeToString()) , but I got issue on deploy_model, I have no idea to save the whole net and data into the deploy_model
