Web一、什么是混合精度训练在pytorch的tensor中，默认的类型是float32，神经网络训练过程中，网络权重以及其他参数，默认都是float32，即单精度，为了节省内存，部分操作使用float16，即半精度，训练过程既有float32，又有float16，因此叫混合精度训练。 Webbounty还有4天到期。回答此问题可获得+50声望奖励。Alain Michael Janith Schroter希望引起更多关注此问题。. 我尝试使用nn.BCEWithLogitsLoss()作为initially使用nn.CrossEntropyLoss()的模型。 然而，在对训练函数进行一些更改以适应nn.BCEWithLogitsLoss()损失函数之后，模型精度值显示为大于1。 coconino county injunction against harassment https://boonegap.com
