Functions

bool_to_numeric

bool_to_numeric[dtype: DType](array: NDArray[DType.bool]) -> NDArray[dtype]

Convert a boolean NDArray to a numeric NDArray.

Parameters:

• dtype (DType): The data type of the output NDArray elements.

Args:

• array (NDArray): The boolean NDArray to convert.

Returns:

• NDArray

Raises

to_numpy

to_numpy[dtype: DType](array: NDArray[dtype]) -> PythonObject

Convert a NDArray to a numpy array.

Example:

var arr = NDArray[DType.float32](3, 3, 3)
var np_arr = to_numpy(arr)
var np_arr1 = arr.to_numpy()

Parameters:

• dtype (DType): The data type of the NDArray elements.

Args:

• array (NDArray): The NDArray to convert.

Returns:

• PythonObject
