This function does not support ``mode`` option. Args: a (cupy.ndarray): Array to extract elements. indices (int or array-like): Indices of elements that this function takes. axis (int): The axis along which to select indices. The flattened input is used by default. out (cupy.ndarray): Output array. If provided, it should be of appropriate shape and dtype. Returns: cupy.ndarray: The result of fancy indexing. .. seealso:: :func:`numpy.take` )take)aindicesaxisouts k/home/jaya/work/projects/VOICE-AGENT/VIET/agent-env/lib/python3.11/site-packages/cupy/_indexing/indexing.pyrrs. 66'4 % %%c|jjdvrtd||}d}|j}t j||}||jkrtdg}t|j D]o\}}||kr| |!d|zdzd||z dz zz}| tj | |p|t|S) awTake values from the input array by matching 1d index and data slices.

Args: condition (1-D array of bools): Array that selects which entries to return. If len(condition) is less than the size of a along the given axis, then output is truncated to the length of the condition array. a (cupy.ndarray): Array from which to extract a part. axis (int): Axis along which to take slices.

This function extracts the diagonals along two specified axes. The other axes are not changed. This function returns a writable view of this array as NumPy 1.10 will do. Args: a (cupy.ndarray): Array from which the diagonals are taken. offset (int): Index of the diagonals. Zero indicates the main diagonals, a positive value upper diagonals, and a negative value lower diagonals. axis1 (int): The first axis to take diagonals from. axis2 (int): The second axis to take diagonals from.

This is equivalent to ``np.compress(ravel(condition), ravel(arr))``. If ``condition`` is boolean, ``np.extract`` is equivalent to ``arr[condition]``. Args: condition (int or array_like): An array whose nonzero or True entries indicate the elements of array to extract. a (cupy.ndarray): Input array of the same size as condition.

Args: condlist (list of bool arrays): The list of conditions which determine from which array in `choicelist` the output elements are taken. When multiple conditions are satisfied, the first one encountered in `condlist` is used. choicelist (list of cupy.ndarray): The list of arrays from which the output elements are taken. It has to be of the same length as `condlist`. default (scalar) : If provided, will fill element inserted in `output` when all conditions evaluate to False. default value is 0.
