使用非符号张量的输入调用了Layer

Question

我遵循了在this page上找到的代码。

当我复制粘贴代码时，出现错误：

ValueError: Layer batch_normalization_1 was called with an input that isn't a symbolic tensor.

与博客作者不同，我得到错误的原因是什么？

Answer 1

似乎您没有在“密集”层中输入内容。

feature_input = Input(shape=(sentences_features.shape[1],))
dense = Dense(128, activation=activations.relu)
merged = BatchNormalization()(dense)

尝试：

dense = Dense(128, activation=activations.relu)(feature_input)
