The following links have instructions for how to run ResNet50 (v1.5) for the following modes/precisions:
The original ResNet model has multiple versions which have shown better accuracy and/or batch inference and training performance. As mentioned in TensorFlow's official ResNet model page, 3 different versions of the original ResNet model exists - ResNet50v1, ResNet50v1.5, and ResNet50v2. As a side note, ResNet50v1.5 is also in MLPerf's cloud inference benchmark for image classification and training benchmark.
