Pytorch float16
Webtorch.cuda.amp provides convenience methods for mixed precision, where some operations use the torch.float32 ( float) datatype and other operations use torch.float16 ( half ). Some ops, like linear layers and convolutions, are much faster in float16 or bfloat16. Other ops, like reductions, often require the dynamic range of float32.

WebMar 25, 2024 · float16: ( optional ) By default, model uses float32 in computation. If this flag is specified, half-precision float will be used. This option is recommended for NVidia GPU with Tensor Core like V100 and T4. For older GPUs, float32 is likely faster. use_gpu: ( optional ) When opt_level > 1, please set this flag for GPU inference. WebApr 10, 2024 · The training batch size is set to 32.)

If your code doesn't create nan/inf numbers or turn a non- 0 into a 0 with float32, then it shouldn't do it with bfloat16 either, roughly speaking. So, if your hardware supports it, I'd pick that.
