⚡ Quick Start

Add several lines to your python code for visualizing and saving graphs.

import anetomy
import torch
from torch import nn
import torch.nn.functional as F

# define the toy model
class Dense(nn.Module):
    def __init__(self):
        super().__init__()
        self.lin = nn.Linear(28*28*2, 10)

    def forward(self, x):
        x = F.relu(x, inplace=True)
        x = x.reshape(-1,)
        y = self.lin(x)
        return y
          
class NeuralNetwork(nn.Module):
    def __init__(self):
        super().__init__()
        self.conv1 = nn.Conv2d(3, 8, 3, padding=1)
        self.mpool1 = nn.MaxPool2d(3, stride=2, ceil_mode=True)
        self.dense = Dense()

    def forward(self, x, scale=1):
        x *= scale
        y = self.conv1(x)
        y = self.mpool1(y)
        y = self.dense(y)
        return y

# input dummy data to visualize
net = NeuralNetwork()
dummy_x = torch.randn(1, 3, 28, 28)
dummy_s = 2
anv = anetomy.NetVue(graph_path='./toynn.png')
anv.dissect(net, dummy_x, scale=dummy_s)
# use render() to save network image directly
anv.render(3) # set the max depth to expand as 3
# use launch() to run a web server for inspection
anv.launch('127.0.0.1', port=7880)
