AttributeError: 'numpy.ndarray' object has no attribute 'y'
时间: 2023-10-28 18:06:39 浏览: 293
This error occurs when you try to access the attribute "y" of a numpy array, which does not exist.
For example, if you have a numpy array called "data" and you try to access its "y" attribute using "data.y", you will get this error because numpy arrays do not have a "y" attribute.
To fix this error, you need to check the structure of your data and make sure you are accessing the correct attributes. If you are trying to access the "y" values of a dataset, you may need to use indexing or slicing to extract the correct values from the numpy array.

AttributeError: numpy.ndarray object has no attribute corr
这个错误通常是因为在使用 `corr()` 方法时,对象不是 pandas DataFrame 或 Series 类型,而是 numpy.ndarray 类型。因此,需要将 numpy 数组转换为 DataFrame 或 Series 类型,然后再使用 `corr()` 方法。
例如,如果你有一个名为 `arr` 的 numpy 数组,你可以将其转换为 DataFrame 类型:
```python
import pandas as pd
import numpy as np
arr = np.array([[1, 2], [3, 4]])
df = pd.DataFrame(arr)
corr_matrix = df.corr()
```
这样就可以使用 `corr()` 方法计算 DataFrame 的相关性矩阵了。
