numpy.zeros(shape, dtype=None, order='C', *, device=None, like=None)
Return a new array of given shape and type, filled with zeros.
Parameters:shapeint or tuple of intsShape of the new array, e.g., (2,3) or 2.
dtypedata-type, optionalThe desired data-type for the array, e.g.,
. Default is
.
order{‘C’, ‘F’}, optional, default: ‘C’Whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran-style) order in memory.
devicestr, optionalThe device on which to place the created array. Default: None. For Array-API interoperability only, so must be "cpu" if passed.
Added in version 2.0.0.
likearray_like, optionalReference object to allow the creation of arrays which are not NumPy arrays. If an array-like passed in as like supports the __array_function__ protocol, the result will be defined by it. In this case, it ensures the creation of an array object compatible with that passed in via this argument.
Added in version 1.20.0.
Returns:outndarrayArray of zeros with the given shape, dtype, and order.
