用于简化 torch 模型训练的工具
Project description
TorchCat
简介
TorchCat 能够用于简化你的模型训练
用法
导入库
from torch import Cat
封装你的模型
# 你的模型
net = nn.Sequential(
nn.Flatten(),
nn.Linear(28*28, 128),
nn.ReLU(),
nn.Linear(128, 10),
)
net = Cat(model=net,
loss_fn=nn.CrossEntropyLoss(),
optimizer=torch.optim.Adam(net.parameters(), lr=0.0001))
参数 |
说明 |
|---|---|
model |
你的模型 |
loss_fn |
选择损失函数 |
optimizer |
选择优化器 |
Cat.summary()
在封装模型后,使用 net.summary(),可以查看模型的架构。input_size 参数需填写模型的输入形状,如 net.summary(1, 28, 28)
Cat.train()
使用 net.train(),可以开始模型的训练
log,可以记录训练时的训练日志,包括
训练集损失(log['train loss'])
训练集准确率(log['train acc'])
验证集损失(log['valid loss'])
验证集准确率(log['validacc'])
log = net.train(train_set=train_set, epochs=5, valid_set=test_set)
参数 |
说明 |
|---|---|
train_set |
训练集 |
epochs |
训练轮次 |
valid_set |
验证集 |
