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。 WebMar 21, 2024 · Gradient Clipping is a method where the error derivative is changed or clipped to a threshold during backward propagation through the network, and using the clipped gradients to update the weights. By rescaling the error derivative, the updates to the weights will also be rescaled, dramatically decreasing the likelihood of an overflow or …
