mindsponge.common.rots_to_tensor

mindsponge.common.rots_to_tensor(rots, use_numpy=False)

Translate rots represented by vectors to tensor, inverse of ‘rots_from_tensor’.

Parameters

• rots (Tuple) – Rots represented by vectors, shape is $(xx,xy,xz,yx,yy,yz,zx,zy,zz)$ .

• use_numpy (bool) – Whether to use numpy to calculate. Default: False.

Returns

Tensor, concat the tensor in last dims, shape $(N_{res},3,3)$.

Supported Platforms:

Ascend GPU

Examples

>>> import numpy as np
>>> import mindspore as ms
>>> from mindspore import Tensor
>>> from mindsponge.common.geometry import rots_to_tensor
>>> inputs = [Tensor(np.ones((256,)), ms.float32) for i in range(9)]
>>> output = rots_to_tensor(inputs)
>>> print(output.shape)
(256, 3, 3)
