AttributeError: 'PngImageFile' object has no attribute 'shape'是一个错误提示,意味着在对一个PngImageFile对象调用shape属性时出错。可能的原因是该对象并没有shape属性。你可以检查一下你的代码,看看是否有其他可用的属性或方法来获取图像的形状信息。

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)
```
AttributeError: 'JpegImageFile' object has no attribute 'shape'. Did you mean: 'save'?
这个错误通常是因为你正在尝试在一个NoneType对象上调用find_all方法。这意味着你的代码中某个变量的值为None,而不是一个有效的对象。要解决这个错误,你可以检查变量的值是否为None,并确保它是一个有效的对象,然后再调用相应的方法。
另外,对于错误"AttributeError: 'JpegImageFile' object has no attribute 'shape'. Did you mean: 'save'?",这意味着你正在尝试在一个JpegImageFile对象上调用shape属性,但该对象没有shape属性。根据错误信息的建议,你可能想使用save方法来保存该图像,而不是访问shape属性。
以下是解决这两个错误的示例代码:
1. 解决AttributeError: 'NoneType' object has no attribute 'find_all'错误:
```python
# 检查变量是否为None
if variable is not None:
# 调用find_all方法
variable.find_all()
else:
# 处理变量为None的情况
# ...
```
2. 解决AttributeError: 'JpegImageFile' object has no attribute 'shape'错误:
```python
# 调用save方法保存图像
image.save("image.jpg")
```
