How do I print the model summary in PyTorch?
How do I print the summary of a model in PyTorch like what model.summary() does in Keras:
Model Summary:
____________________________________________________________________________________________________
Layer (type) Output Shape Param # Connected to
====================================================================================================
input_1 (InputLayer) (None, 1, 15, 27) 0
____________________________________________________________________________________________________
convolution2d_1 (Convolution2D) (None, 8, 15, 27) 872 input_1[0][0]
____________________________________________________________________________________________________
maxpooling2d_1 (MaxPooling2D) (None, 8, 7, 27) 0 convolution2d_1[0][0]
____________________________________________________________________________________________________
flatten_1 (Flatten) (None, 1512) 0 maxpooling2d_1[0][0]
____________________________________________________________________________________________________
dense_1 (Dense) (None, 1) 1513 flatten_1[0][0]
====================================================================================================

While you will not get as detailed information about the model as in Keras' model.summary, simply printing the model will give you some idea about the different layers involved and their specifications.
For instance:
from torchvision import models
model = models.vgg16()
print(model)
The output in this case would be something as follows:
VGG (
(features): Sequential (
(0): Conv2d(3, 64, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(1): ReLU (inplace)
(2): Conv2d(64, 64, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(3): ReLU (inplace)
(4): MaxPool2d (size=(2, 2), stride=(2, 2), dilation=(1, 1))
(5): Conv2d(64, 128, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(6): ReLU (inplace)
(7): Conv2d(128, 128, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(8): ReLU (inplace)
(9): MaxPool2d (size=(2, 2), stride=(2, 2), dilation=(1, 1))
(10): Conv2d(128, 256, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(11): ReLU (inplace)
(12): Conv2d(256, 256, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(13): ReLU (inplace)
(14): Conv2d(256, 256, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(15): ReLU (inplace)
(16): MaxPool2d (size=(2, 2), stride=(2, 2), dilation=(1, 1))
(17): Conv2d(256, 512, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(18): ReLU (inplace)
(19): Conv2d(512, 512, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(20): ReLU (inplace)
(21): Conv2d(512, 512, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(22): ReLU (inplace)
(23): MaxPool2d (size=(2, 2), stride=(2, 2), dilation=(1, 1))
(24): Conv2d(512, 512, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(25): ReLU (inplace)
(26): Conv2d(512, 512, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(27): ReLU (inplace)
(28): Conv2d(512, 512, kernel_size=(3, 3), stride=(1, 1), padding=(1, 1))
(29): ReLU (inplace)
(30): MaxPool2d (size=(2, 2), stride=(2, 2), dilation=(1, 1))
)
(classifier): Sequential (
(0): Dropout (p = 0.5)
(1): Linear (25088 -> 4096)
(2): ReLU (inplace)
(3): Dropout (p = 0.5)
(4): Linear (4096 -> 4096)
(5): ReLU (inplace)
(6): Linear (4096 -> 1000)
)
)
Now you could, as mentioned by Kashyap, use the state_dict method to get the weights of the different layers. But using this listing of the layers would perhaps provide more direction is creating a helper function to get that Keras like model summary!

I prefer this simple snippet instead -
net = model
modules = [module for module in net.modules()]
params = [param.shape for param in net.parameters()]
# Print Model Summary
print(modules[0])
total_params=0
for i in range(1,len(modules)):
j = 2*i
param = (params[j-2][1]*params[j-2][0])+params[j-1][0]
total_params += param
print("Layer",i,"->\t",end="")
print("Weights:", params[j-2][0],"x",params[j-2][1],
"\tBias: ",params[j-1][0], "\tParameters: ", param)
print("\nTotal Params: ", total_params)
This prints everything I need -
Net(
(hLayer1): Linear(in_features=1024, out_features=256, bias=True)
(hLayer2): Linear(in_features=256, out_features=128, bias=True)
(hLayer3): Linear(in_features=128, out_features=64, bias=True)
(outLayer): Linear(in_features=64, out_features=10, bias=True)
)
Layer 1 -> Weights: 256 x 1024 Bias: 256 Parameters: 262400
Layer 2 -> Weights: 128 x 256 Bias: 128 Parameters: 32896
Layer 3 -> Weights: 64 x 128 Bias: 64 Parameters: 8256
Layer 4 -> Weights: 10 x 64 Bias: 10 Parameters: 650
Total Parameters: 304202
For a complex model or a more indepth stats of the model
Install torchstat
pip install torchstat
Get stats
from torchstat import stat
import torchvision.models as models
model = models.vgg19()
stat(model, (3, 224, 224))
Output -

The torchinfo (formerly torchsummary) package produces analogous output to Keras1 (for a given input shape):2

Notes:
-
Torchinfo provides information complementary to what is provided by
print(your_model)in PyTorch, similar to Tensorflow'smodel.summary()... Unlike Keras, PyTorch has a dynamic computational graph which can adapt to any compatible input shape across multiple calls e.g. any sufficiently large image size (for a fully convolutional network).
As such, it cannot present an inherent set of input/output shapes for each layer, as these are input-dependent, and why in the above package you must specify the input dimensions.

In order to use torchsummary type:
from torchsummary import summary
Install it first if you don't have it.
pip install torchsummary
And then you can try it, but note for some reason it is not working unless I set model to cuda alexnet.cuda:
from torchsummary import summary
help(summary)
import torchvision.models as models
alexnet = models.alexnet(pretrained=False)
alexnet.cuda()
summary(alexnet, (3, 224, 224))
print(alexnet)
The summary must take the input size and batch size is set to -1 meaning any batch size we provide.
If we set summary(alexnet, (3, 224, 224), 32) this means use the bs=32.
summary(model, input_size, batch_size=-1, device='cuda')
Out:
Help on function summary in module torchsummary.torchsummary:
summary(model, input_size, batch_size=-1, device='cuda')

summary(my_model, (3, 224, 224), device = 'cpu') will solve the issue.

Yes, you can get exact Keras representation, using the pytorch-summary package.
Example for VGG16:
from torchvision import models
from torchsummary import summary
vgg = models.vgg16()
summary(vgg, (3, 224, 224))

Keras like model summary using torchsummary:
from torchsummary import summary
summary(model, input_size=(3, 224, 224))

You can use
from torchsummary import summary
You can specify device
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
You can create a Network, and if you are using MNIST datasets, then following commands will work and show you summary
model = Network().to(device)
summary(model,(1,28,28))

Simply print the model after defining an object for the model class
class RNN(nn.Module):
def __init__(self, input_dim, embedding_dim, hidden_dim, output_dim):
super().__init__()
self.embedding = nn.Embedding(input_dim, embedding_dim)
self.rnn = nn.RNN(embedding_dim, hidden_dim)
self.fc = nn.Linear(hidden_dim, output_dim)
def forward():
...
model = RNN(input_dim, embedding_dim, hidden_dim, output_dim)
print(model)

Simplest to remember (not as pretty as Keras):
print(model)
This also work:
repr(model)
If you just want the number of parameters:
sum([param.nelement() for param in model.parameters()])
From: Is there similar pytorch function as model.summary() as keras? (forum.PyTorch.org)

This will show a model's weights and parameters (but not output shape).
from torch.nn.modules.module import _addindent
import torch
import numpy as np
def torch_summarize(model, show_weights=True, show_parameters=True):
"""Summarizes torch model by showing trainable parameters and weights."""
tmpstr = model.__class__.__name__ + ' (\n'
for key, module in model._modules.items():
# if it contains layers let call it recursively to get params and weights
if type(module) in [
torch.nn.modules.container.Container,
torch.nn.modules.container.Sequential
]:
modstr = torch_summarize(module)
else:
modstr = module.__repr__()
modstr = _addindent(modstr, 2)
params = sum([np.prod(p.size()) for p in module.parameters()])
weights = tuple([tuple(p.size()) for p in module.parameters()])
tmpstr += ' (' + key + '): ' + modstr
if show_weights:
tmpstr += ', weights={}'.format(weights)
if show_parameters:
tmpstr += ', parameters={}'.format(params)
tmpstr += '\n'
tmpstr = tmpstr + ')'
return tmpstr

Edit: isaykatsman has a pytorch PR to add a model.summary() that is exactly like keras https://github.com/pytorch/pytorch/pull/3043/files
