'Equal' Op 的输入 'y' 的类型 bool 与参数 'x' 的 float32 类型不匹配 [英] Input 'y' of 'Equal' Op has type bool that does not match type float32 of argument 'x'

问题描述

我正在从事语音数字识别项目.

I am working on spoken digit recognition project.

模型定义:

input_layer = Input(shape = (max_length, 1))      //Takes input vectors
input_mask = Input(shape = (max_length))          //Takes boolean mask vectors (False for zero else true)
LSTM_layer = LSTM(25)(input_layer, mask = input_mask)
dense = Dense(50, 'relu')(LSTM_layer)
dense_1 = Dense(10, 'softmax')(dense)
model = Model(inputs = [input_layer, input_mask], outputs = dense_1)

推荐答案

我想通了.只需在两个输入层中指定 dtype 如下:

I figured it out. Just specify the dtype in both input layers as below :

input_layer = Input(shape = (max_length, 1), dtype='float32')
input_mask = Input(shape = (max_length), dtype='bool')
LSTM_layer = LSTM(25)(input_layer, mask = input_mask)
dense = Dense(50, 'relu')(LSTM_layer)
dense_1 = Dense(10, 'softmax')(dense)
model = Model(inputs = [input_layer, input_mask], outputs = dense_1)
