Description

Does amp support PyTorch 1.0.0? Or shall I rather use the FP16_Optimizer? As far as my what I have understood, amp is a more advanced version of FP16_Optimizer which performs unsafe ops in FP32. The distinction and which one should be used is not super clear from the documentation but I guess that I will have to use FP16_Optimizer as amp doesn't seem to have full support for PyTorch 1.0.0 yet.
