python - 鼠洞 : 'scipy.spatial.transform.rotation.Rotation' object has no attribute 'as_dcm'

Question

我正在尝试使用 ratcave for python 创建一个项目。但是当我导入 ratcave 时，出现以下错误:

AttributeError: 'scipy.spatial.transform.rotation.Rotation' object has no attribute 'as_dcm'

这是完整的堆栈跟踪:

Traceback (most recent call last):

    self.model_matrix = np.dot(self.position.to_matrix(), self.rotation.to_matrix())
  File "PROJECT_PATH\venv\lib\site-packages\ratcave\coordinates.py", line 126, in to_matrix
    return self.to_radians().to_matrix()
  File "PROJECT_PATH\venv\lib\site-packages\ratcave\coordinates.py", line 95, in to_matrix
    mat[:3, :3] = R.from_euler(self.axes[1:],self._array,degrees=False).as_dcm() # scipy as_matrix() not available
AttributeError: 'scipy.spatial.transform._rotation.Rotation' object has no attribute 'as_dcm'. Did you mean: '_uniforms'?

这是我的代码:

import pyglet
import ratcave as rc


# Create Window
window = pyglet.window.Window()


pyglet.app.run()

Answer 1

好像方法名改成了from_matrix。

在scipy.spatial.Rotation方法from_dcm中，as_dcm被重命名为from_matrix，as_matrix 分别。

希望问题得到解决。
