下载 ResNet50 数据时连接重置错误

如何解决下载 ResNet50 数据时连接重置错误

什么可能导致此错误？

是因为互联网还是防火墙？

这个问题只出现在 resnet50 中，VGG16 中没有。

import keras
from keras.models import Sequential
from keras.layers import Dense
from keras.preprocessing.image import ImageDataGenerator
from keras.applications import resnet50
from keras.applications.resnet50 import preprocess_input as rs_pi
from keras.applications import vgg16
from keras.applications.vgg16 import preprocess_input as vgg_pi


model = Sequential()
model.add(resnet50(
    include_top=False,pooling='avg',weights='imagenet',))
model.add(Dense(num_classes,activation='softmax'))
model.summary()

   1101                 return self._sslobj.read(len)

ConnectionResetError: [Errno 104] Connection reset by peer

如果是防火墙的原因，我该如何修复它或者甚至可以修复它？

因为代码内容比较多，为了贴出这个问题，我不得不写更多，所以我删除了部分错误信息的中心部分
