Question

我正在关注转学习的在线教程，我遇到了这个问题：这是代码：

train_data = np.load(open('bottleneck_features_train.npy', 'rb'))
train_labels = np.array(
    [0] * (nb_train_samples / 2) + [1] * (nb_train_samples / 2))

validation_data = np.load(open('bottleneck_features_validation.npy'))
validation_labels = np.array(
    [0] * (nb_validation_samples / 2) + [1] * (nb_validation_samples / 2))

我收到此错误：

[0] * (nb_train_samples / 2) + [1] * (nb_train_samples / 2))
can't multiply sequence by non-int of type 'float'

Answer 1

问题是[0]和[1]是列表。列表的乘法运算符是重复它，只有乘以整数才有可能。所以[1]*2==[1,1]。如果这是期望的结果，那么您只需简单地对它们进行int： [0] * int(nb_train_samples / 2) + [1] * int(nb_train_samples / 2))

错误不能将序列乘以'float'类型的非int
