'Path3DCollection' object has no attribute 'shape'

`'Path3DCollection' object has no attribute 'shape'` 错误提示表明你在使用一个名为 `shape` 的属性时,将其应用于了一个 `Path3DCollection` 对象上,但是这个对象并没有 `shape` 属性,因此 Python 报错了。
一种可能的原因是你的代码中使用了一个名为 `shape` 的变量或对象,导致与你期望的不同。你可以尝试在代码中搜索 `shape`,看看是否有其他地方也使用了这个名称。
另外,`Path3DCollection` 是 Matplotlib 中用于绘制 3D 图形的对象,如果你想要获取 `Path3DCollection` 对象的形状信息,可以使用 `get_paths()` 方法获取所有路径信息,并对路径信息进行处理。例如,可以通过以下代码获取 `Path3DCollection` 对象的形状:
```python
paths = path_collection.get_paths()
shapes = [p.vertices.shape for p in paths]
```
其中,`path_collection` 是你要获取形状信息的 `Path3DCollection` 对象,`get_paths()` 方法返回所有路径信息的列表,`p.vertices` 返回路径的顶点坐标,`p.vertices.shape` 返回路径的形状,即顶点数量和坐标维度。最终,`shapes` 是一个形状信息的列表,每个元素是一个二元组,表示一个路径的形状。

问题:AttributeError: 'Path3DCollection' object has no attribute '_offsets3d'
回答: 这个错误通常是由于路径集合对象没有属性'_offsets3d'导致的。具体解决方法可以尝试在绘制路径集合之前设置'_offsets3d'属性。<span class="em">1</span>

'Poly3DCollection' object has no attribute '_facecolors2d'
This error message is typically encountered when using the Poly3DCollection class from the matplotlib library.
The Poly3DCollection object is used to represent a collection of 3D polygons, and is often used in conjunction with the Axes3D class.
The error message suggests that the '_facecolors2d' attribute is missing from the object. This attribute is used to store the colors of the polygon faces in 2D space.
There are several possible reasons why this error message might occur. One possible cause is that the Poly3DCollection object was not properly initialized with the necessary attributes. Another possible cause is that the object was modified in some way that caused the '_facecolors2d' attribute to be deleted or corrupted.
To fix this error, you may need to review your code and ensure that the Poly3DCollection object is properly initialized with all necessary attributes. If the object was modified in some way, you may need to revert the changes or create a new object with the correct settings.
