NDArray

The multidimensional data array class.

Methods

__iter__	Iterate over the (outer) elements of the array.
__len__
__getitem__	Retrieve a (multidimensional) slice as specified by the key.
__setitem__	Set a slice of the array.
copy	Create a copy of an array with different parameters.
get_chunk	Shortcut to SChunk.get_chunk.
indices	Return the indices of a sorted array following the specified order.
iterchunks_info	Iterate over self chunks of the array, providing information on index and special values.
reshape	Return a new array with the specified shape.
resize	Change the shape of the array by growing or shrinking one or more dimensions.
save	Save the array to a file.
slice	Get a (multidimensional) slice as a new NDArray.
sort	Return a sorted array following the specified order, or the order of the fields.
squeeze	Remove single-dimensional entries from the shape of the array.
tobytes	Returns a buffer containing the data of the entire array.
to_cframe	Get a bytes object containing the serialized NDArray instance.

In addition, all the functions from the Lazy Functions section can be used with NDArray instances.

Attributes

ndim	The number of dimensions of this container.
shape	Returns the data shape of this container.
ext_shape	The padded data shape.
chunks	Returns the data chunk shape of this container.
ext_chunks	Returns 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	Returns 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.
keep_last_read	Indicates whether the last read data should be kept in memory.
info	Print information about this array.
schunk	The SChunk reference of the NDArray.
size	The size (in bytes) for this container.
cparams	The compression parameters used by the array.
dparams	The decompression parameters used by the array.
urlpath	The URL path of the array.
vlmeta	The variable-length metadata of the array.

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.
fromiter	Create a new array from an iterable object.
nans	Create an array with NaNs values.
ndarray_from_cframe	Create a NDArray instance from a contiguous frame buffer.
uninit	Create an array with uninitialized values.
zeros	Create an array with zero as the default value for uninitialized portions of the array.
ones	Create an array with one as values.
full	Create an array, with fill_value being used as the default value for uninitialized portions of the array.
arange	Return evenly spaced values within a given interval.
linspace	Return evenly spaced numbers over a specified interval.
eye	Return a 2-D array with ones on the diagonal and zeros elsewhere.
reshape	Returns an array containing the same data with a new shape.
