'DataFrame' object has no attribute 'to_frame'
提问by Serdia
I am new to python. Just following the tutorial: https://www.hackerearth.com/practice/machine-learning/machine-learning-projects/python-project/tutorial/
我是python的新手。只需遵循教程：https: //www.hackerearth.com/practice/machine-learning/machine-learning-projects/python-project/tutorial/
This is the dataframe miss:
这是数据帧未命中：
miss = train.isnull().sum()/len(train)
miss = miss[miss>0]
miss.sort_values(inplace = True)
miss

Now I just want to visualize those missing values"
现在我只想可视化那些缺失的值”
#visualising missing values
miss = miss.to_frame()
miss.columns = ['count']
miss.index.names = ['Name']
miss['Name'] = miss.index
And this is the error I got:
这是我得到的错误：
AttributeError Traceback (most recent call last)
<ipython-input-42-cd3b25e8862a> in <module>()
1 #visualising missing values
----> 2 miss = miss.to_frame()
C:\Users\Username\AppData\Local\Continuum\Anaconda3\lib\site-packages\pandas\core\generic.py in __getattr__(self, name)
2742 if name in self._info_axis:
2743 return self[name]
-> 2744 return object.__getattribute__(self, name)
2745
2746 def __setattr__(self, name, value):
AttributeError: 'DataFrame' object has no attribute 'to_frame'
What am I missing here?
我在这里错过了什么？

Check print(type(miss))it should be <class 'pandas.core.series.Series'>
检查print(type(miss))它应该是<class 'pandas.core.series.Series'>
You have is dataframe, somewhere in the code you are doing wrong.
您拥有的是数据框，在代码中的某处您做错了。
df = pd.DataFrame()
df.to_frame()
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Users\UR_NAME\AppData\Local\Programs\Python\Python36\lib\site-packages\pandas\core\generic.py", line 3614, in __getattr__
return object.__getattribute__(self, name)
AttributeError: 'DataFrame' object has no attribute 'to_frame'
I traced the tutorial, and below is the order flow
我跟踪了教程，下面是订单流程
train = pd.read_csv("train.csv")
print(type(train)) # <class 'pandas.core.frame.DataFrame'>
miss = train.isnull().sum()/len(train)
print(type(miss)) # <class 'pandas.core.series.Series'>
miss = train.isnull().sum()/len(train)converts in into pandas.core.series.Seriesfrom pandas.core.frame.DataFrame
miss = train.isnull().sum()/len(train)转换成pandas.core.series.Series从pandas.core.frame.DataFrame
You are probably messed code at this place.
你可能在这个地方搞砸了代码。
