'LegacyPPIDataset' object has no attribute 'labels'. Did you mean: '_labels'?
时间: 2023-08-30 21:13:09 浏览: 59
这个错误提示表明在 LegacyPPIDataset 对象中没有 'labels' 属性,但是可能存在 '_labels' 属性。这个错误通常发生在代码中尝试访问一个不存在的属性或者变量时。你可以检查一下你的代码,确认 LegacyPPIDataset 对象是否正确初始化,并且是否有 'labels' 属性。如果是一个私有属性 '_labels',则需要使用下划线访问。你也可以检查一下数据集对象的定义,确认其是否正确定义了 'labels' 属性。

AttributeError: 'LegacyPPIDataset' object has no attribute 'labels'. Did you mean: '_labels'?怎么解决
这个错误提示中说 LegacyPPIDataset 对象没有 labels 属性,但是建议你检查是否有一个名为 _labels 的属性。这通常意味着你的代码中可能有一个拼写错误或者属性名写错了。
你可以尝试检查代码中访问 labels 属性的地方,看看是否有写错属性名的地方。如果你确定代码中需要使用 labels 属性,可以在 LegacyPPIDataset 类中添加 labels 属性。例如,你可以在 LegacyPPIDataset 类中增加以下代码:
```python
class LegacyPPIDataset:
...
def __init__(self, ...):
...
self.labels = _labels
```
这样就可以在 LegacyPPIDataset 对象中使用 labels 属性了。但是在添加属性之前,你需要确认使用 _labels 属性是否符合你的需求。
AttributeError: DataFrame object has no attribute append . Did you mean: _append ?
This error occurs when you try to call the `append` method on a Pandas DataFrame object, but the object does not have an `append` attribute.
One possible reason for this error is that you are trying to append a DataFrame to another DataFrame using the `append` method, but you are not using it correctly. In Pandas, the `append` method does not modify the original DataFrame, but instead it returns a new DataFrame that contains the rows from both DataFrames. Therefore, you need to assign the result of the `append` method to a new variable or to the original DataFrame, like this:
```
df1 = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
df2 = pd.DataFrame({'A': [5, 6], 'B': [7, 8]})
df3 = df1.append(df2)
```
In this example, `df3` will contain the rows from both `df1` and `df2`.
If you are still getting the AttributeError, it's possible that the DataFrame object you are trying to append to does not have an `append` attribute. In this case, you can try using the `_append` attribute instead, which is a private method that is used internally by Pandas. However, be aware that using private methods may not be supported in future versions of Pandas and may cause unexpected behavior.
```
df1._append(df2)
```
