NDArray

The multidimensional data array class. This class consists of a set of useful parameters and methods that allow not only to create an array correctly, but also to being able to extract multidimensional slices from it (and much more).

Methods

__getitem__	Get a (multidimensional) slice as specified in key.
__setitem__	Set a slice.
copy	Create a copy of an array with same parameters.
get_chunk	Shortcut to SChunk.get_chunk.
iterchunks_info	Iterate over self chunks, providing info on index and special values.
slice	Get a (multidimensional) slice as a new NDArray.
squeeze	Remove the 1's in array's shape.
resize	Change the shape of the array by growing or shrinking one or more dimensions.
tobytes	Returns a buffer with the data contents.
to_cframe	Get a bytes object containing the serialized NDArray instance.

Attributes

ndim	The number of dimensions of this container.
shape	The data shape of this container.
ext_shape	The padded data shape.
chunks	The data chunk shape of this container.
ext_chunks	The padded chunk shape which defines the chunksize in the associated schunk.
blocks	The block shape of this container.
blocksize	The block size (in bytes) for this container.
chunksize	The data chunk size (in bytes) for this container.
dtype	Data-type of the array’s elements.
fields	Dictionary with the fields of the structured array.
info	Print information about this array.
schunk	The SChunk reference of the NDArray.
size	The size (in bytes) for this container.

Constructors

asarray	Convert the array to an NDArray.
copy	This is equivalent to NDArray.copy()
empty	Create an empty array.
frombuffer	Create an array out of a buffer.
full	Create an array, with fill_value being used as the default value for uninitialized portions of the array.
nans	Create an array with NaNs values.
ndarray_from_cframe	Create a NDArray instance out of a contiguous frame buffer.
uninit	Create an array with uninitialized values.
zeros	Create an array, with zero being used as the default value for uninitialized portions of the array.
