AttributeError: 'DataFrame' object has no attribute 'array'

这个错误是因为 DataFrame 对象没有 `array` 属性。`array` 是 numpy 库中的一个函数,用于将 DataFrame 转换为数组。如果你想将 DataFrame 转换为数组,可以使用 `values` 属性来实现。
以下是一个示例代码:
```python
import pandas as pd
# 创建一个DataFrame对象
data = {'col1': [1,2, 3], 'col2': [4, 5, 6

AttributeError: 'DataFrame' object has no attribute 'reshape'
`reshape` is a method of Numpy arrays and is not directly available in Pandas DataFrames. If you want to reshape a DataFrame, you can first convert it to a Numpy array using the `values` attribute, and then use the `reshape` method:
```python
import pandas as pd
# create a DataFrame
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6], 'C': [7, 8, 9]})
# convert to a Numpy array and reshape
arr = df.values.reshape((3, 3))
```
Alternatively, you can use the `stack` method to reshape the DataFrame into a Series, and then use the `values` attribute to convert it to a Numpy array:
```python
# stack the DataFrame and convert to a Numpy array
arr = df.stack().values.reshape((3, 3))
```
Note that the shape of the reshaped array should match the number of elements in the original DataFrame.
AttributeError: 'DataFrameGroupBy' object has no attribute 'values'
在你的问题中,你提到了一个错误:AttributeError: 'DataFrameGroupBy' object has no attribute 'values'。这个错误是由于在DataFrameGroupBy对象上调用了values属性,而该属性在该对象上不存在。根据引用和引用的内容,我可以给出以下解决方案:
1. 首先,你可以尝试使用sort_values()方法来对DataFrame进行排序,而不是使用sort属性。根据引用的描述,这个属性是不存在的。因此,你可以尝试使用sort_values()方法来解决这个问题。
2. 另外,你还可以使用其他方法来获取DataFrame对象的值。根据引用的描述,你可以尝试使用df.values或者np.array(df)来获取DataFrame对象的值,而不是使用df.as_matrix()方法。这两种方法都可以替代df.as_matrix()方法。
综上所述,你可以尝试使用sort_values()方法来对DataFrame进行排序,并使用df.values或者np.array(df)方法来获取DataFrame对象的值,以解决AttributeError: 'DataFrameGroupBy' object has no attribute 'values'的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span><span class="em">4</span>
