The AWS Deep Learning AMIs now come with TensorFlow 1.5, and Microsoft Cognitive Toolkit 2.4, with support for NVIDIA CUDA 9 and cuDNN 7 drivers. AMI users can now take advantage of the mixed precision training on the V100 Volta GPUs powering EC2 P3 instances. In our earlier tests for TensorFlow 1.5 on Volta , training the ResNet-50 benchmark with synthetic ImageNet data in FP16 mode on a p3.8xlarge instance was 1.8x times faster than training with TensorFlow 1.4.1.
