属性错误：模块'numpy'没有属性'testing'

Question

上周我能够在python 3.7.2中运行程序。

今天早上我进来，运行相同的程序并获得错误

AttributeError: module 'numpy' has no attribute 'testing'

我进行了新的卸载和安装Python 3.7.2

然后我做了 pip3 install -U scikit-learn scipy matplotlib，运行了相同的程序并仍然遇到此错误。

花了整个早晨谷歌搜索，并尝试不同的事情（当然，重新启动机器，检查路径）

请帮助!!!!!

代码（其他代码触发器）

# Assigning features and label variables
# First Feature
weather=['Sunny','Sunny','Overcast','Rainy','Rainy','Rainy','Overcast','Sunny','Sunny',
'Rainy','Sunny','Overcast','Overcast','Rainy']
# Second Feature
temp=['Hot','Hot','Hot','Mild','Cool','Cool','Cool','Mild','Cool','Mild','Mild','Mild','Hot','Mild']
# Label or target varible
play=['No','No','Yes','Yes','Yes','No','Yes','No','Yes','Yes','Yes','Yes','Yes','No']

# Import LabelEncoder
from sklearn import preprocessing
# creating labelEncoder
le = preprocessing.LabelEncoder()
# converting string labels into numbers
weather_encoded = le.fit_transform(weather)
print(weather_encoded)
# converting string labels into numbers
temp_encoded = le.fit_transform(temp)
label = le.fit_transform(play)
# combining weather and temp into a single list of tuples
features = list(zip(weather_encoded,temp_encoded))

from sklearn.neighbors import KNeighborsClassifier
model = KNeighborsClassifier(n_neighbors=3)
# Train the model using the training sets
model.fit(features, label)
# Predict Output
predicted = model.predict([[0,2]]) #0:Overcast, 2:Mild
print(predicted)

运行其他导入代码，示例：

import np.testing as npt
npt.assert_array_almost_equal(answer1, answer2 )
