>>> import blosc2
>>> import numpy as np
>>> shape = (10, 10)

>>> dtype = np.bool_
>>> # Create a NDArray with default chunks
>>> a = blosc2.zeros(shape, blocks=blocks, dtype=dtype)
>>> # Get a copy with default chunks and blocks
>>> b = a.copy(chunks=None, blocks=None)
>>> np.array_equal(b[...], a[...])
True
