AttributeError: 'numpy.ndarray' object has no attribute 'numpy'

This error occurs when you try to access the `numpy` attribute of a `numpy.ndarray` object, but the attribute doesn't exist. For example, consider the following code: ```python import numpy as np arr = np.array([1, 2, 3]) arr.numpy() ``` When you try to execute the `arr.numpy()` line, you'll get the `AttributeError` because there's no `numpy` attribute in the `ndarray` object. To fix this error, you need to remove the `.numpy()` part of the code and simply use the `arr` object directly. For example: ```python import numpy as np arr = np.array([1, 2, 3]) print(arr) ``` This will print the contents of the `arr` object, which is `[1 2 3]`.

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。
