how to debug torch lua program

[fireman]

Hi, I am new to lua and help you can help me. I downloaded a torch lua convolutional neural network program from online and would like to study it. The network has many layers in it. I would like to step through each layer of them and exam the input and output of each layer. How can I do it? Currently I am using ZeroBrane Studio. 

Thanks a lot

Hi, 

You can configure eclipse with torch for debugging.

To visualize the contents of a network you simply need to execute a forward pass of your input through the network and then you can access each individual layer's contents such as output, weights, bias, etc. You can do this using breakpoints in zbstudio or just simply launch a terminal, type "th" or "qlua", load your network, generate an input and do a :forward(). To access any layer in your network, you can simply do "net.modules[id]".

Follow Andrej Karpathay's lecture on calculating convoluting steps. I was on a same situation as you, debugging helped little to understand. That lecture gave a more meaningful understanding. CS231n and lecture might be the 6th one.

Just a suggestion.
