# module `concrete.fhe.extensions.ones` Declaration of `ones` and `one` functions, to simplify creation of encrypted ones. --- ## function `ones` ```python ones(shape: Union[int, Tuple[int, ]]) → Union[ndarray, Tracer] ``` Create an encrypted array of ones. **Args:** shape (Tuple[int, ...]): shape of the array **Returns:** Union[np.ndarray, Tracer]: Tracer that respresents the operation during tracing ndarray filled with ones otherwise --- ## function `one` ```python one() → Union[ndarray, Tracer] ``` Create an encrypted scalar with the value of one. **Returns:** Union[np.ndarray, Tracer]: Tracer that respresents the operation during tracing ndarray with one otherwise --- ## function `ones_like` ```python ones_like(array: Union[ndarray, Tracer]) → Union[ndarray, Tracer] ``` Create an encrypted array of ones with the same shape as another array. **Args:** array (Union[np.ndarray, Tracer]): original array **Returns:** Union[np.ndarray, Tracer]: Tracer that represent the operation during tracing ndarray filled with ones otherwise
