WebAug 22, 2024 · RuntimeError:输入和目标形状不匹配:输入 [10 x 133]，目标 [1 x 10] 因此，一种解决方法是将 loss = criterion (outputs,target.view (1, -1)) 替换为 loss = criterion (outputs,target.view (-1, 1)) 并将最后一个线性层的 output_channels 更改为 1 而不是 133.这样 outputs 和 target 的形状就会相等 ... WebThe estimate eventually converges to true mean. Since I want to use a similar implementation using NN , I decided to rearrange the equations to compute Loss. Just for a recap : New_mean = a * old_mean + (1-a)*data. in for loop old mean is initiated to mean_init to start. So Los is : new_mean – old_mean = a * old_mean + (1-a)*data – old_mean.
