ConvNet Research paper Implementation

Hi Folks. I wander anyone had implemented ConvNet like the Lenet5, ResNet etc?

  1. What type of cloud GPU is needed? I guess I do not need very high end GPU right?

I would like to try implementing using either the GPU on AWS or Colab. But I am not too sure if I would chalk up a high cost using GPU. Any insights, suggestions or experience are welcome. Thanks
