hiddenlayer可视化工具--没有显示尺寸大小
解决hiddenlayer可视化工具,中间过程没有显示尺寸大小

1.问题:可视化网络没有显示尺寸的大小
import torch
import hiddenlayer as h
from torchvision.models import alexnet # 以 alexnet 为例
myNet = alexnet() # 实例化 alexnet
x = torch.randn(1, 3, 224, 224) # 随机生成一个输入
myNetGraph = h.build_graph(myNet, x) # 建立网络模型图
# myNetGraph.theme = h.graph.THEMES['blue'] # blue 和 basic 两种颜色,可以不要
myNetGraph.save(path='./demoModel.png', format='png') # 保存网络模型图,可以设置 png 和 pdf 等

2.解决方案:修改底层源码

找到 pytorch_builder.py 文件,修改 get_shape(torch_node) 函数如下:
def get_shape(torch_node):
"""Return the output shape of the given Pytorch node."""
# Extract node output shape from the node string representation
# This is a hack because there doesn't seem to be an official way to do it.
# See my quesiton in the PyTorch forum:
# https://discuss.pytorch.org/t/node-output-shape-from-trace-graph/24351/2
# TODO: find a better way to extract output shape
# TODO: Assuming the node has one output. Update if we encounter a multi-output node.
shape = torch_node.output().type().sizes()
return shape

3.处理后的结果:

4.安装hiddenlayer库
方法一、通过命令行cmd,然后输入pip install hiddenlayer(我已经安装过,所以下面显示已经安装)

方法二、进入官网,进行下载源码,运行py文件实现
