python3-cyarray 1.1-2build1 (s390x binary) in ubuntu focal

 The cyarray package provides a fast, typed, re-sizable, Cython array.
 .
 It currently provides the following arrays: ``IntArray, UIntArray,
 LongArray, FloatArray, DoubleArray``.
 .
 All arrays provide for the following operations:
 .
  - access by indexing.
  - access through get/set function.
  - resizing the array.
  - appending values at the end of the array.
  - reserving space for future appends.
  - access to internal data through a numpy array.
 .
 If you are writing Cython code this is a convenient array to use as it
 exposes the raw underlying pointer to the data.
 For example if you use a ``FloatArray`` and access its ``data``
 attribute it will be a ``float*``.
 .
 Each array also provides an interface to its data through a numpy
 array.
 This is done through the ``get_npy_array`` function.
 The returned numpy array can be used just like any other numpy array
 but for the following restrictions:
 .
  - the array may not be resized.
  - references of this array should not be kept.
  - slices of this array may not be made.
 .
 The numpy array may however be copied and used in any manner.
