I used to analyze the C code of the Torch7, I should say Torch7 should be a very fast framework and the drawback is that I think Torch7 is a little bit more resource consuming, it achieves faster training and inference speed at the cost of requiring more memory.Another point is that Torch7’s I/O API (Application Programming Interface) is so user friendly, the only thing that you need to load an image it to call an imread function with the argument of “/path/of/your/image/data.jpg”.But, for tensorflow, the basic tutorial didn’t tell you how to load your own data to form an efficient input data.

I still cannot remember all the related APIs it mentioned. I know that there are some dataset already existing on Kaggle but it would certainly be nice to construct our personal ones to test our own ideas and find the limits of what neural networks can and cannot achieve.
