mindscience.e3nn.o3.so3_generators

mindscience.e3nn.o3.so3_generators(l, dtype=mindspore.float32)

Compute the so(3) Lie algebra generators.

Parameters

• l (int) – degree of generators.

• dtype (mindspore.dtype, optional) – {mindspore.float32, mindspore.float64} data type of generators. Default: mindspore.float32.

Returns

Tensor, so(3) generators with the dtype is mindspore.dtype.

Raises

• TypeError – If l is not int.

• ValueError – If matrices data are inconsistent.

Examples

>>> from mindscience.e3nn.o3 import so3_generators
>>> m = so3_generators(1)
>>> print(m)
