各模型的py文件中仅包含此模型，main.py为主文件，compare.py用于比较各个模型（已选取最优参数），plot.py中整合了画图，方便调用
参数--model 选定模型
参数--lr 学习率 可以多填
参数--dropout 可以多填
参数--plot 是否画图
参数--epoch 轮次
示例：
python .\main.py --model googlenet --lr 0.001 0.0005 0.0001 --dropout 0 0.2 0.4 --plot true --epoch 5内置了五个经典模型以及合适的学习率，运行以下代码即可
python .\compare.py
