我要评论在练习吴恩达第二周课后作业“猫的识别”时，下载的资源文件lr_utils.py中“ train_set_y_orig.shape[0]”会提示“Value 'train_set_y_orig.shape' is unsubscriptablepylint(unsubscriptable-object)”，不知道是什么原因，大家是否遇到？
lr_utils.py文件代码如下：
import numpy as np
import h5py
def load_dataset():
train_dataset = h5py.File('datasets/train_catvnoncat.h5', "r")
train_set_x_orig = np.array(train_dataset["train_set_x"[:]) # your train set features
train_set_y_orig = np.array(train_dataset["train_set_y"][:]) # your train set labels
test_dataset = h5py.File('datasets/test_catvnoncat.h5', "r")
test_set_x_orig = np.array(test_dataset["test_set_x"][:]) # your test set features
test_set_y_orig = np.array(test_dataset["test_set_y"][:]) # your test set labels
classes = np.array(test_dataset["list_classes"][:]) # the list of classes
train_set_y_orig = train_set_y_orig.reshape((1, train_set_y_orig.shape[0]))
test_set_y_orig = test_set_y_orig.reshape((1, test_set_y_orig.shape[0]))
return train_set_x_orig, train_set_y_orig, test_set_x_orig, test_set_y_orig, classes
自己又随便写了一段代码验证了一下：
import numpy as np
a=np.zeros((3,5))
print(a.shape)
b=a.shape[0]
print(b)
print(type(a.shape))
仍然会报错，提示：“Value 'a.shape' is unsubscriptablepylint(unsubscriptable-object)”
但是代码可以运行，结果如下：
(3, 5)
3
<class 'tuple'>
不知道问题出在哪里？
