pytorch nn.Conv2d()中的padding以及输出大小方式
This line of code creates a 2D convolutional layer using the PyTorch library. The layer will take in an input tensor with 3 channels (e.g. RGB image) and output a tensor with 64 channels. The kernel size is set to 4, which means the convolutional filter will be a 4x4 matrix. The stride is set to 2, which means the filter will move 2 pixels at a time across the input image. The padding is set to 1, which means a border of 1 pixel will be added around the input image to ensure that the output size is the same as the input size.
