Question

我正在尝试使用一个Conv1D操作定义一个基本的ConvNet，如下所示：

n_class = 10

# channels last (default)
input_shape = (100, 1)
inp = Input(shape=input_shape)
x = Conv1D(4, kernel_size=9, activation=activations.relu, padding='same')(inp)

x = MaxPool1D(pool_size=5)(x)
x = Flatten()(x)
out = Dense(n_class, activation='softmax')(x)

model = Model(inputs=inp, outputs=out)

并且工作正常（默认情况下使用data_format ='channels_last'）。但是，如果我想使用data_format ='channels_first'：

# "channels_first" inputs with shape (batch, channels, length).
input_shape = (1, 100)
inp = Input(shape=input_shape)
x = Conv1D(4, kernel_size=9, activation=activations.relu, data_format='channels_first', padding='same')(inp)

x = MaxPool1D(pool_size=5, data_format='channels_first')(x)
x = Flatten()(x)
out = Dense(n_class, activation='softmax')(x)

model = Model(inputs=inp, outputs=out)

定义Conv1D层时出现以下错误：

    globals = debugger.run(setup['file'], None, None, is_module)

    **kwargs)
TypeError: __init__() got multiple values for keyword argument 'data_format'

对于做错了什么的任何见解？谢谢！

您似乎没有使用最新的代码（不仅仅是最新版本）。对于Conv1D层，即使在最新版本2.1.6中也不支持data_format='channels_first'。您需要克隆并使用master分支中的代码。该支持由this commit于5/7/2018添加。文档始终与主文件同步，这可能会造成混淆。 The idea (from the Keras creator François Chollet)就是那个

仅存在
版本以强制PyPI用户升级。它们没有意义。你应该经常同步掌握。

您可以找到一些旧的Keras文档here。

带有data_format channels_first的Conv1D会在Keras
