AttributeError:模块"numpy"没有属性"testing" [英] AttributeError: module 'numpy' has no attribute 'testing'

问题描述

上周，我能够在Python 3.7.2中运行程序.

Last week I was able to run programs in Python 3.7.2 just fine.

今天早上我进来，运行相同的程序并得到错误

This morning I come in, run the same program and get error

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

我做了全新的python 3.7.2卸载和安装

I did fresh uninstall and install of python 3.7.2

然后我做了pip3 install -U scikit-learn scipy matplotlib，运行了相同的程序，但仍然收到此错误.

Then I did pip3 install -U scikit-learn scipy matplotlib, ran same program(s) and still getting this error.

整个上午都在谷歌搜索上花了很多时间，尝试了不同的方法(当然，重新启动计算机，检查了PATH)

Spent the whole morning googling, and trying different things (and of course, rebooted machine, checked PATH)

请帮助！！！!!!

# 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)

推荐答案

运行其他导入代码，例如:

run an additional import code, example:

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