Thank you so much. That is really helpful. Can I ask one more question, please? Well, I wrote a code which allowed the system to randomly choose different convolution layers with different kernel sizes and the kernel size is the only difference between each convolution layers. For example, 3 conv layers: 3X3, 1X1,5X5. But how can I get the information of the kernel size and save them in an array or a string after I create this model?
