ValueError：无法为Tensor'x：0'提供shape（0，）的值，其形状为'（？，400,600,1）'

Question

运行神经网络时出现上述错误：

UNIQUE (phone_number), UNIQUE (email)

以下是我的神经网络的要点：

print('Checking the Training on a Single Batch...')
with tf.Session() as sess:
    # Initializing the variables
    sess.run(tf.global_variables_initializer())

    # Training cycle
    for epoch in range(epochs):
        batch_i = 1
        for batch_features, batch_labels in (input_data, input_labels):
            train_neural_network(sess, optimizer, keep_probability, batch_features, batch_labels)
        print('Epoch {:>2}, Batch {}:  '.format(epoch + 1, batch_i), end='')
        print_stats(sess, batch_features, batch_labels, cost, accuracy)

我有更好的方法来创建标签吗？
