For example, to convert a tensor from float32 to int32: import torch a = torch.tensor([1.0, 2.0, 3.0]) b = a.to(torch.int32) In this example, the tensor "a" is converted to int32 data type and assigned to the tensor "b". It is important to note that notall conversions betwe...

开发者只需借助convert_to_float8_training这个小工具,便可轻松将模型训练转为float8,像开了外挂似的轻松实现高效训练。而在推理方面,torchao同样有着不俗的表现。它不仅提供多种量化策略,如权重量化和动态激活量化,用户可以根据自己的需求,自由选择最适合的量化方式,以此获得最佳的推理性能。对开发者而言,这就...
