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

Question

I'm trying to create a project using ratcave for python. But when I import ratcave, I get the following error:

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

and this is the full stacktrace:

    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'?

This is my code:

import pyglet
import ratcave as rc


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


pyglet.app.run()

Answer 1

It seems that the method name has changed to from_matrix.

In scipy.spatial.Rotation methods from_dcm, as_dcm were renamed to from_matrix, as_matrix respectively.

I hope that problem is resolved.
