Question

我对神经网络非常陌生，我正在尝试使用Keras来构建鱼分类器。我得到了一个使用Keras和tensorflow-backend来创建RESNET-50模型的python代码，该代码使用model.save（）输出一个h5文件。

我编写了另一个python文件，以从h5文件重新加载RESNET-50模型。我使用keras.models.load_model（）加载h5文件。但是python给我以下错误消息，我不知道为什么。谢谢，请帮我。

Answer 1

D:\Anaconda3\lib\site-packages\keras\initializers.py in __init__(self, scale, mode, distribution, seed)
    193             raise ValueError('Invalid `distribution` argument: '
    194                              'expected one of {"normal", "uniform"} '
--> 195                              'but got', distribution)
    196         self.scale = scale
    197         self.mode = mode

ValueError: ('Invalid `distribution` argument: expected one of {"normal", "uniform"} but got', 'truncated_normal')

在import tensorflow.python.keras中替换keras。然后成功了。

（Keras）无法从h5文件重新加载经过训练的resnet50模型
