I thought perhaps we could add an example of the outputs on a large model. I noticed that some of these summary packages break down in the presence of large models, even though these are the ones you most need to summarise.

torchsummaryX
Improved visualization tool of torchsummary. Here, it visualizes kernel size, output shape, # params, and Mult-Adds. Also the torchsummaryX can handle RNN, Recursive NN, or model with multiple inputs.
Usage
pip install torchsummaryX and
from torchsummaryX import summary
summary(your_model, torch.zeros((1, 3, 224, 224)))
Args:
model(Module): Model to summarizex(Tensor): Input tensor of the model with [N, C, H, W] shape dtype and device have to match to the modelargs, kwargs: Other arguments used inmodel.forwardfunction
Examples
CNN for MNIST
class Net(nn.Module):
def __init__(self):
super(Net, self).__init__()
self.conv1 = nn.Conv2d(1, 10, kernel_size=5)
self.conv2 = nn.Conv2d(10, 20, kernel_size=5)
self.conv2_drop = nn.Dropout2d()
self.fc1 = nn.Linear(320, 50)
self.fc2 = nn.Linear(50, 10)
def forward(self, x):
x = F.relu(F.max_pool2d(self.conv1(x), 2))
x = F.relu(F.max_pool2d(self.conv2_drop(self.conv2(x)), 2))
x = x.view(-1, 320)
x = F.relu(self.fc1(x))
x = F.dropout(x, training=self.training)
x = self.fc2(x)
return F.log_softmax(x, dim=1)
