'DataFrame' object has no attribute 'as_matrix'什么意思

这个错误通常表示你在使用Pandas的DataFrame对象时,调用了`as_matrix()`方法,但是该方法已经在Pandas版本0.24.0中被弃用了。
你可以使用`values`属性来获取DataFrame中的数据,例如`df.values`。或者使用`to_numpy()`方法来获取DataFrame中的数据,例如`df.to_numpy()`。这两种方法都可以将DataFrame对象转换为NumPy数组,以便进行计算和分析。

'DataFrame' object has no attribute 'as_matrix
The error message "AttributeError: 'DataFrame' object has no attribute 'as_matrix'" means that you are trying to access the 'as_matrix' attribute of a Pandas DataFrame object, but this attribute does not exist. The 'as_matrix' method was removed in Pandas version 0.24.0, as it was deemed to be confusing and potentially dangerous.
To fix this error, you can replace the 'as_matrix' method with the 'values' property, which returns the underlying NumPy array of the DataFrame. For example, if you have a DataFrame called 'df', you would replace:
```
X = df.as_matrix()
```
with:
```
X = df.values
```
This should solve the error and allow you to access the values of the DataFrame.
'DataFrame' object has no attribute 'as_matrix'
The error message "DataFrame object has no attribute 'as_matrix'" usually occurs when you are trying to call the "as_matrix()" method on a pandas DataFrame object, which has been removed since version 0.24.0.
To fix this error, you can replace the "as_matrix()" method with the "values" attribute, which returns a NumPy array containing the same data as the DataFrame. For example, instead of calling:
```python
X = df.as_matrix()
```
You can call:
```python
X = df.values
```
This should fix the error and allow you to retrieve the data from the DataFrame as a NumPy array.
