taichi.types.ext_arr()

Type annotation for external arrays.

External arrays are formally defined as the data from other Python frameworks. For now, Taichi supports numpy and pytorch.

Example:

>>> @ti.kernel
>>> def to_numpy(arr: ti.ext_arr()):
>>>     for i in x:
>>>         arr[i] = x[i]
>>>
>>> arr = numpy.zeros(...)
>>> to_numpy(arr)  # `arr` will be filled with `x`'s data.

taichi.types.any_arr

Alias for ArgAnyArray.

Example:

>>> @ti.kernel
>>> def to_numpy(x: ti.any_arr(), y: ti.any_arr()):
>>>     for i in range(n):
>>>         x[i] = y[i]
>>>
>>> y = ti.ndarray(ti.f64, shape=n)
>>> ... # calculate y
>>> x = numpy.zeros(n)
>>> to_numpy(x, y)  # `x` will be filled with `y`'s data.
