dask.array.empty_like¶
dask.array.empty_like(a, dtype=None, order='C', chunks=None, name=None, shape=None)[source]¶
Return a new array with the same shape and type as a given array.
Parameters
aarray_like
The shape and data-type of a define these same attributes of the returned array.
dtypedata-type, optional
Overrides the data type of the result.
order{‘C’, ‘F’}, optional
Whether to store multidimensional data in C- or Fortran-contiguous (row- or column-wise) order in memory.
chunkssequence of ints
The number of samples on each block. Note that the last block will have fewer samples if len(array) % chunks != 0.
namestr, optional
An optional keyname for the array. Defaults to hashing the input keyword arguments.
shapeint or sequence of ints, optional.
Overrides the shape of the result.
Returns
outndarray
Array of uninitialized (arbitrary) data with the same shape and type as a.
See also
Return an array of ones with shape and type of input.
Return an array of zeros with shape and type of input.
Return a new uninitialized array.
Return a new array setting values to one.
Return a new array setting values to zero.
Notes
This function does not initialize the returned array; to do that usezeros_like or ones_like instead. It may be marginally faster than the functions that do set the array values.
