      You now can train a really good image classification model on 25k images in less than 2 hours, entirely for free, on a Colab GPU. And it's dead easy. What a time to be alive I remember when you had to write your own CUDA and C++ and you needed a hardware budget

      Here's a Colab that does just that. Download a zip file with 25k images. Get a model training in seconds, with all the best practices baked in. One hour and a half to convergence on the free Colab GPU.https://colab.research.google.com/drive/1umJnCp8tZ7UDTYSQsuWdKRhqbHts38AC …

          I'm still learning this stuff trying to understand - so I have two questions about the model: 1. When you first enter the for loop you have an activation in series with another activation. What is the point of that? 2. When you leave the for loop there is no activation? Why not?

          Noob question but if you wanted to try Xception on CIFAR-10 what would you change? Would you upscale from 32x32 or change the model?
