torch.nn.Flatten(start_dim=1, end_dim=- 1) 作用:将连续的维度范围展平为张量。 经常在nn.Sequential()中出现,一般写在某个神经网络模型之后,用于对神经网络模型的输出进行处理,得到tensor类型的数据。 有俩个参数,start_dim和end_dim,分别表示开始的维度和终止的维度,默认值分别是1和-1,其中1表示第一维度...

其实就是contiguous(连续性)的问题,在pytorch issue上有这样的warning: UserWarning: RNN module weights are not part of single contiguous chunk of memory. This means they need to be compacted at every call, possibly greately increasing memory usage.To compact weights again call flatten_parameters(). ...
如果pytorch没有提供需要的预处理类,我们可以参照源码仿造写一个自定义处理的类来进行处理。例如对图片添加白噪声,按通道变换颜色等等。
optimizer = optim.SGD(model.parameters(), lr=0.01, momentum=0.5) #封装训练函数 def train(epoch): #初始化训练损失 running_loss = 0.0 #训练 for batch_idx,data in enumerate(train_loader, 0): #导入数据 inputs, target = data #梯度归零 ...
fine pytorch tune实例 pytorch flatten函数 一、继承nn.Module类并自定义层 我们要利用pytorch提供的很多便利的方法,则需要将很多自定义操作封装成nn.Module类。 首先,简单实现一个Mylinear类: from torch import nn # Mylinear继承Module class Mylinear(nn.Module):...
