I added self.__model.half() before
ampere_model_library/utils/pytorch.py
Line 46 in 209549f
and tested a few models. All of them stopped working, but they threw slightly different errors:
- resnet_50_v1 and a few others threw
RuntimeError: "rsqrt_cpu" not implemented for 'Half' - alexnet and ssd_vgg_16 threw
RuntimeError: expected scalar type Float but found Half - roberta_base_squad threw
RuntimeError: "LayerNormKernelImpl" not implemented for 'Half'
Looks like half() only works on GPUs.

Yes, it is expected. Since x86 doesn't support fp16 natively, nobody cared about this on CPU. However Altra supports it natively, so when eager mode will be implemented I expect it to work.
