[英]How can I convert my numpy array into a pandas dataframe?
I have a numpy array called heart_rate with size (1181,) I tried to convert it into a pandas dataframe using the following code: 我有一个名为heart_rate的numpy数组,大小为(1181,),我尝试使用以下代码将其转换为熊猫数据框:
dataset = pd.DataFrame({'Column 1':heart_rate[:,0]})
But I got the following error: 但我收到以下错误:
IndexError: too many indices for array
IndexError:数组索引过多
Just do: 做就是了:
dataset = pd.DataFrame({'Column 1':heart_rate})
or 要么
dataset = pd.DataFrame(heart_rate, columns=['Column 1'])
your error is that you're trying to slice the array with too many indexers, it's a 1-D array 您的错误是您尝试使用过多索引器对数组进行切片,这是一维数组
example: 例:
In[2]:
heart_rate = np.arange(1,10)
heart_rate.shape
Out[2]: (9,)
In[3]:
df = pd.DataFrame(heart_rate, columns=['Column 1'])
df
Out[3]:
Column 1
0 1
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9
and 和
In[4]:
df = pd.DataFrame({'Column 1':heart_rate})
df
Out[4]:
Column 1
0 1
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9
Here you can see that it's your slicing that is generating the error: 在这里,您可以看到生成错误的是您的切片:
heart_rate[:,0]
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
<ipython-input-5-e1eba9de0086> in <module>()
----> 1 heart_rate[:,0]
IndexError: too many indices for array
