无法在 jupyter notebook 中绘制直方图

Question

我无法在 Jupyter 笔记本中绘制直方图。这是下面的代码和响应它的错误消息。

import pandas as pd
import numpy as np
from sklearn.datasets import load_boston
import matplotlib.pyplot as plt

housing_data = load_boston()
%matplotlib inline
housing_data.hist(bins = 50, figsize = (20, 15))
plt.show()

KeyError                                  Traceback (most recent call last)
/anaconda3/lib/python3.6/site-packages/sklearn/utils/__init__.py in          __getattr__(self, key)
60         try:
---> 61             return self[key]
62         except KeyError:

KeyError: 'hist'

During handling of the above exception, another exception occurred:

AttributeError                            Traceback (most recent call last)
<ipython-input-17-570a88b85d5d> in <module>()
----> 1 housing_data.hist(bins = 50, figsize = (20, 15))
2 plt.show();

/anaconda3/lib/python3.6/site-packages/sklearn/utils/__init__.py in    __getattr__(self, key)
 61             return self[key]
 62         except KeyError:

---> 63 raise AttributeError(key) 64 65 def setstate (self, state):

AttributeError: hist

我是新手，请帮助我。

Answer 1

import pandas as pd
import numpy as np
from sklearn.datasets import load_boston
import matplotlib.pyplot as plt

housing_data = load_boston()
%matplotlib inline


pd.DataFrame(housing_data['data']).hist(bins = 50, figsize = (20, 15))

您必须访问包含数据的 numpy 数组字典，然后将其转换为 Pandas 数据框才能使用 .hist
