from their note on github page [1]: > The time required to train the Show and Tell model depends on your specific hardware and computational capacity. > In this guide we assume you will be running training on a single machine with a GPU. In our experience on an NVIDIA Tesla K20m GPU the initial training phase takes 1-2 weeks. The second training phase may take several additional weeks to achieve peak performance (but you can stop this phase early and still get reasonable results). > It is possible to achieve a speed-up by implementing distributed training across a cluster of machines with GPUs, > but that is not covered in this guide. > Whilst it is possible to run this code on a CPU, beware that this may be approximately 10 times slower. So, I assume it will take veeery long time to train it on a MBP, unless they publish their pre-trained data-set.
