Torch 7 is a GPU accelerated deep learning framework. It had been rather obscure until recent publicity caused by adoption by Facebook and DeepMind. This entirely anecdotal article describes our experiences trying to load some data in Torch. We had great expectations about Torch. It seemed like a dream come true, especially with endorsement by DeepMind and LeCun's group at Facebook.
