cupy.empty_like

cupy.empty_like(a, dtype=None, order='K', subok=None, shape=None)[source]

Returns a new array with same shape and dtype of a given array.

This function currently does not support subok option.

Parameters
  • a (cupy.ndarray) – Base array.

  • dtype – Data type specifier. The data type of a is used by default.

  • order ({'C', 'F', 'A', or 'K'}) – Overrides the memory layout of the result. ‘C’ means C-order, ‘F’ means F-order, ‘A’ means ‘F’ if a is Fortran contiguous, ‘C’ otherwise. ‘K’ means match the layout of a as closely as possible.

  • subok – Not supported yet, must be None.

  • shape (int or tuple of ints) – Overrides the shape of the result. If order=’K’ and the number of dimensions is unchanged, will try to keep order, otherwise, order=’C’ is implied.

Returns

A new array with same shape and dtype of a with elements not initialized.

Return type

cupy.ndarray
