Shape aware loss pytorch
Webb18 maj 2024 · 因为一般损失函数都是直接计算 batch 的数据,因此返回的 loss 结果都是维度为 (batch_size, ) 的向量。 如果 reduce = False,那么 size_average 参数失效,直接返回向量形式的 loss; 如果 reduce = True,那么 loss 返回的是标量 如果 size_average = True,返回 loss.mean (); 如果 size_average = True,返回 loss.sum (); 所以下面讲解的 … WebbGot: {}".format(input.shape))ifnotinput.shape[-2:]==target.shape[-2:]:raiseValueError("input and target shapes must be the same.
