python - Errno 13 权限被拒绝 Keras VGG16

问题描述

我正在尝试从 Keras 加载 VGG16 模型来执行迁移学习，

input_shape = (224, 224, 3)
model = VGG16(weights='imagenet', include_top=False, input_shape=input_shape)

但我收到以下错误：

Traceback (most recent call last):

  File "<ipython-input-27-898653ab5324>", line 1, in <module>
    model = VGG16(weights='imagenet', include_top=False)

PermissionError: [Errno 13] Permission denied

这真的很奇怪，因为加载 VGG19 网络对我没有任何问题。此外，如果我删除“include_top”参数，模型会成功加载而不会引发错误。

# This works fine
model = VGG16(weights='imagenet')

有人能帮忙吗？谢谢。

解决方案

您可以从 tensorflow 导入，而不是从 keras 导入。

from tensorflow.keras.applications import VGG16

这将解决您的问题
