This function may also be used as a decorator. Parameters ---------- func : function The function to be deprecated. old_name : str, optional The name of the function to be deprecated. Default is None, in which case the name of `func` is used. new_name : str, optional The new name for the function. Default is None, in which case the deprecation message is that `old_name` is deprecated. If given, the deprecation message is that `old_name` is deprecated and `new_name` should be used instead. message : str, optional Additional explanation of the deprecation. Displayed in the docstring after the warning. Returns ------- old_func : function The deprecated function. Examples -------- Note that ``olduint`` returns a value after printing Deprecation Warning: >>> olduint = np.deprecate(np.uint) DeprecationWarning: `uint64` is deprecated! # may vary >>> olduint(6) 6 r r2 N)r" )r. r? �fnr r r r � s , c C s t | d�S )a� Deprecates a function and includes the deprecation in its docstring.

Parameters ---------- a : ndarray Input array. It must conform to the Python-side of the array interface. Returns ------- (low, high) : tuple of 2 integers The first integer is the first byte of the array, the second integer is just past the last byte of the array. If `a` is not contiguous it will not use every byte between the (`low`, `high`) values. Examples -------- >>> I = np.eye(2, dtype='f'); I.dtype dtype('float32') >>> low, high = np.byte_bounds(I) >>> high - low == I.size*I.itemsize True >>> I = np.eye(2); I.dtype dtype('float64') >>> low, high = np.byte_bounds(I) >>> high - low == I.size*I.itemsize True �datar �strides�shapeNr2 )Z__array_interface__r �dtype�itemsize�size�zip) �aZaiZa_dataZastridesZashapeZbytes_aZa_lowZa_highrO Zstrider r r r � s c C sP | dkrt �� j}|j} g }i }x�| �� D ]�}t| | t�r*| | }t|�}||�� krn|d|| }d}n|||< |}d}d�t t |j ��} t |j �} |� || | |jj|g� q*W d} d} d} d}x�tt|��D ]|}|| }| t|d �k r�t|d �} | t|d �k �rt|d �} | t|d �k �r8t|d �} |d r�|t|d �7 }q�W t|�dk�r�td| �}td| �}td| �}d |d |d |d f }t|d d t|�d d � x�tt|��D ]t}|| }td|d d |t|d � d |d d |t|d � d |d d |t|d � d |d f � �q�W td| � dS )a% Print the NumPy arrays in the given dictionary.

Parameters ---------- object : object or str, optional Input object or name to get information about. If `object` is a numpy object, its docstring is given. If it is a string, available modules are searched for matching objects. If None, information about `info` itself is returned. maxwidth : int, optional Printing width. output : file like object, optional File like object that the output is written to, default is ``stdout``. The object has to be opened in 'w' or 'a' mode. toplevel : str, optional Start search at this level. See Also -------- source, lookfor Notes ----- When used interactively with an object, ``np.info(obj)`` is equivalent to ``help(obj)`` on the Python prompt or ``obj?`` on the IPython prompt. Examples -------- >>> np.info(np.polyval) # doctest: +SKIP polyval(p, x) Evaluate the polynomial p at x. ... When using a string for `object` it is possible to get multiple results. >>> np.info('fft') # doctest: +SKIP *** Found in numpy *** Core FFT routines ... *** Found in numpy.fft *** fft(a, n=None, axis=-1) ... *** Repeat reference found in numpy.fft.fftpack *** *** Total of 3 references found. *** r NZ_ppimport_importer�_ppimport_module�_ppimport_attr)r� z+ *** Repeat reference found in %s *** )r� z *** Found in %s ***�-r2 zHelp for %s not found.z+ *** Total of %d references found. ***z()r3 r( r' c S s g | ]}|d dkr|�qS )r �_r )�.0�methr r r � <listcomp>h s zinfo.<locals>.<listcomp>z Methods: �Nonez %s -- %sr5 ) �pydoc�inspect�hasattrr� r� r r^ r r� ra � _namedictr~ � _dictlistr_ rg rc �KeyError� isfunction�ismethodr � signature� Exceptionr: rt �getdoc�isclassr' Z allmethodsr� Zsplitdoc)�objectZmaxwidthr� �toplevelr� r� ZnumfoundZobjlistrl r� r rq ZargstrZdoc1�methodsZpublic_methodsr� ZthisobjZmethstr�otherr r r r � s� 4 c C sZ ddl }y,td|�| � |d� t|�| �|d� W n tk rT td|d� Y nX dS )a� Print or write to a file the source code for a NumPy object. The source code is only returned for objects written in Python. Many functions and classes are defined in C and will therefore not return useful information. Parameters ---------- object : numpy object Input object. This can be any object (function, class, module, ...). output : file object, optional If `output` not supplied then source code is printed to screen (sys.stdout). File object must be created with either write 'w' or append 'a' modes.

A list of objects that matched the search is displayed, sorted by relevance. All given keywords need to be found in the docstring for it to be returned as a result, but the order does not matter. Parameters ---------- what : str String containing words to look for. module : str or list, optional Name of module(s) whose docstrings to go through. import_modules : bool, optional Whether to import sub-modules in packages. Default is True. regenerate : bool, optional Whether to re-generate the docstring cache. Default is False. output : file-like, optional File-like object to write the output to. If omitted, use a pager. See Also -------- source, info Notes ----- Relevance is determined only roughly, by checking if the keywords occur in the function name, at the start of a docstring, etc. Examples -------- >>> np.lookfor('binary representation') # doctest: +SKIP Search results for 'binary representation' ------------------------------------------ numpy.binary_repr Return the binary representation of the input number as a string. numpy.core.setup_common.long_double_representation Given a binary dump as given by GNU od -b, look for long double numpy.base_repr Return a string representation of a number in the given base system. ... r N)r{ r� c 3 s | ]}|� kV qd S )Nr )r� �w)r@ r r � <genexpr>� s zlookfor.<locals>.<genexpr>i� i���)r �classr{ r� c s� d}d� |�� �� �d�d d� �� |t� fdd��D ��7 }|t�fdd��D ��7 }|t�� d 7 }|��|d�7 }|��d � d 7 }|t| d d �7 }|S ) Nr r( rY c s g | ]}|� krd �qS )�� r )r� r� )� first_docr r r� s z.lookfor.<locals>.relevance.<locals>.<listcomp>c s g | ]}|� krd �qS )� r )r� r� )r r r r� s rX i����.rV �d i����) r �lower�stripr7 �sumr: �get�countrf )r Zdocstr�kind�index�r)�kind_relevance�whats)r� r r � relevance� s zlookfor.<locals>.relevancec s �| f� | �� S )Nr )rT )rj r� r r �relevance_value s z lookfor.<locals>.relevance_value)�keyzSearch results for '%s'r3 r� ���c S s g | ]}|� � r|� � �qS r )r� )r� rC r r r r� s zlookfor.<locals>.<listcomp>r( r2 rp z %s %szNothing found.rV )r� �_lookfor_generate_cachera r� r7 �items�allrc �sortr r: r� �_function_signature_re�search� IndexError�writeZgetpagerrg )�whatr{ �import_modules� regenerater� r� �foundr Z docstringr� r� r� �s� help_textZixZdoclinesr� �pagerr )rj r@ r� r� r� r r � sJ / c C s� ddl }ddlm} | dkr d} t| t�rXy t| � W n tk rJ i S X tj| } n<t| t �slt| t �r�i }x | D ]}|� t |||�� qvW |S t | �tkr�|s�tt | � S i }|tt | �< i }d}| j| fg} �x�| �r�| �d�\} } t | �|kr�q�d|t | �< |d7 }d} |�| ��r.d} y | j} W n tk �rF d} Y nX |�rNt| d ��rNx�| jD ]�}x�t�|�D ]�}tj�||�}tj�||d �}tj�|��r�|�d ��r�|dd � }ntj�|��rr|}n�qr|d k�r�qryDtj }tj }z$|� t_ |� t_ td| |f � W d|t_ |t_ X W n t k �r@ �wrY nX �qrW �qbW x�t | �D ]�\}}y$t |dd| |f �}t |dd�}W n& t!k �r� d| |f }d}Y nX d|k�r�|�r�d||f }|�"| d ��s�t|t#��rXn�qXn$|�|��s| dk�s|| k�s�qX| �$d| |f |f� �qXW nP|�%| ��rnd} x>t | �D ] \}}| �$d| |f |f� �qHW nt| d��r~d} y|�&| �}W n t!k �r� d}Y nX |dk r�|| |f|| < q�W |S )a� Generate docstring cache for given module.
