+# These are the Cython pxd files for (most of) the Python/C API.
+#
+# REFERENCE COUNTING:
+#
+#   JUST TO SCARE YOU:
+#   If you are going to use any of the Python/C API in your Cython
+#   program, you might be responsible for doing reference counting.
+#   Read http://docs.python.org/api/refcounts.html which is so
+#   important I've copied it below.
+#
+# For all the declaration below, whenever the Py_ function returns
+# a *new reference* to a PyObject*, the return type is "object".
+# When the function returns a borrowed reference, the return
+# type is PyObject*.  When Cython sees "object" as a return type
+# it doesn't increment the reference count.  When it sees PyObject*
+# in order to use the result you must explicitly cast to <object>,
+# and when you do that Cython increments the reference count whether
+# you want it to or not, forcing you to an explicit DECREF (or leak memory).
+# To avoid this we make the above convention.  Note, you can
+# always locally override this convention by putting something like
+#
+#     cdef extern from "Python.h":
+#         PyObject* PyNumber_Add(PyObject *o1, PyObject *o2)
+#
+# in your .pyx file or into a cimported .pxd file.  You just have to
+# use the one from the right (pxd-)namespace then.
+#
+# Cython automatically takes care of reference counting for anything
+# of type object.
+#
+## More precisely, I think the correct convention for
+## using the Python/C API from Cython is as follows.
+##
+## (1) Declare all input arguments as type "object".  This way no explicit
+##    <PyObject*> casting is needed, and moreover Cython doesn't generate
+##    any funny reference counting.
+## (2) Declare output as object if a new reference is returned.
+## (3) Declare output as PyObject* if a borrowed reference is returned.
+##
+## This way when you call objects, no cast is needed, and if the api
+## calls returns a new reference (which is about 95% of them), then
+## you can just assign to a variable of type object.  With borrowed
+## references if you do an explicit typecast to <object>, Cython generates an
+## INCREF and DECREF so you have to be careful.  However, you got a
+## borrowed reference in this case, so there's got to be another reference
+## to your object, so you're OK, as long as you relealize this
+## and use the result of an explicit cast to <object> as a borrowed
+## reference (and you can call Py_INCREF if you want to turn it
+## into another reference for some reason).
+#
+# "The reference count is important because today's computers have
+# a finite (and often severely limited) memory size; it counts how
+# many different places there are that have a reference to an
+# object. Such a place could be another object, or a global (or
+# static) C variable, or a local variable in some C function. When
+# an object's reference count becomes zero, the object is
+# deallocated. If it contains references to other objects, their
+# reference count is decremented. Those other objects may be
+# deallocated in turn, if this decrement makes their reference
+# count become zero, and so on. (There's an obvious problem with
+# objects that reference each other here; for now, the solution is
+# ``don't do that.'')
+#
+# Reference counts are always manipulated explicitly. The normal
+# way is to use the macro Py_INCREF() to increment an object's
+# reference count by one, and Py_DECREF() to decrement it by
+# one. The Py_DECREF() macro is considerably more complex than the
+# incref one, since it must check whether the reference count
+# becomes zero and then cause the object's deallocator to be
+# called. The deallocator is a function pointer contained in the
+# object's type structure. The type-specific deallocator takes
+# care of decrementing the reference counts for other objects
+# contained in the object if this is a compound object type, such
+# as a list, as well as performing any additional finalization
+# that's needed. There's no chance that the reference count can
+# overflow; at least as many bits are used to hold the reference
+# count as there are distinct memory locations in virtual memory
+# (assuming sizeof(long) >= sizeof(char*)). Thus, the reference
+# count increment is a simple operation.
+#
+# It is not necessary to increment an object's reference count for
+# every local variable that contains a pointer to an object. In
+# theory, the object's reference count goes up by one when the
+# variable is made to point to it and it goes down by one when the
+# variable goes out of scope. However, these two cancel each other
+# out, so at the end the reference count hasn't changed. The only
+# real reason to use the reference count is to prevent the object
+# from being deallocated as long as our variable is pointing to
+# it. If we know that there is at least one other reference to the
+# object that lives at least as long as our variable, there is no
+# need to increment the reference count temporarily. An important
+# situation where this arises is in objects that are passed as
+# arguments to C functions in an extension module that are called
+# from Python; the call mechanism guarantees to hold a reference
+# to every argument for the duration of the call.
+#
+# However, a common pitfall is to extract an object from a list
+# and hold on to it for a while without incrementing its reference
+# count. Some other operation might conceivably remove the object
+# from the list, decrementing its reference count and possible
+# deallocating it. The real danger is that innocent-looking
+# operations may invoke arbitrary Python code which could do this;
+# there is a code path which allows control to flow back to the
+# user from a Py_DECREF(), so almost any operation is potentially
+# dangerous.
+#
+# A safe approach is to always use the generic operations
+# (functions whose name begins with "PyObject_", "PyNumber_",
+# "PySequence_" or "PyMapping_"). These operations always
+# increment the reference count of the object they return. This
+# leaves the caller with the responsibility to call Py_DECREF()
+# when they are done with the result; this soon becomes second
+# nature.
+#
+# Now you should read http://docs.python.org/api/refcountDetails.html
+# just to be sure you understand what is going on.

+    # The functions described in this chapter will let you handle and

+    # the Unix errno variable: there is a global indicator (per
+    # thread) of the last error that occurred. Most functions don't
+    # clear this on success, but will set it to indicate the cause of
+    # the error on failure. Most functions also return an error
+    # indicator, usually NULL if they are supposed to return a
+    # pointer, or -1 if they return an integer (exception: the
+    # PyArg_*() functions return 1 for success and 0 for failure).
+
+    # When a function must fail because some function it called
+    # failed, it generally doesn't set the error indicator; the
+    # function it called already set it. It is responsible for either
+    # handling the error and clearing the exception or returning after
+    # cleaning up any resources it holds (such as object references or
+    # memory allocations); it should not continue normally if it is
+    # not prepared to handle the error. If returning due to an error,
+    # it is important to indicate to the caller that an error has been
+    # set. If the error is not handled or carefully propagated,
+    # additional calls into the Python/C API may not behave as

+# although some functions will require later versions. The spacing function is

+#
+# On the Cython side, the npymath functions are available without the "npy_"

+def average_neighbor_degree(G, source="out", target="out", nodes=None, weight=None):
+    r"""Returns the average degree of the neighborhood of each node.
+
+    In an undirected graph, the neighborhood `N(i)` of node `i` contains the
+    nodes that are connected to `i` by an edge.
+
+    For directed graphs, `N(i)` is defined according to the parameter `source`:
+
+        - if source is 'in', then `N(i)` consists of predecessors of node `i`.
+        - if source is 'out', then `N(i)` consists of successors of node `i`.
+        - if source is 'in+out', then `N(i)` is both predecessors and successors.
+
+    The average neighborhood degree of a node `i` is
+
+    .. math::
+
+        k_{nn,i} = \frac{1}{|N(i)|} \sum_{j \in N(i)} k_j
+
+    where `N(i)` are the neighbors of node `i` and `k_j` is
+    the degree of node `j` which belongs to `N(i)`. For weighted
+    graphs, an analogous measure can be defined [1]_,
+
+    .. math::
+
+        k_{nn,i}^{w} = \frac{1}{s_i} \sum_{j \in N(i)} w_{ij} k_j
+
+    where `s_i` is the weighted degree of node `i`, `w_{ij}`
+    is the weight of the edge that links `i` and `j` and
+    `N(i)` are the neighbors of node `i`.
+
+
+    Parameters
+    ----------
+    G : NetworkX graph
+
+    source : string ("in"|"out"|"in+out"), optional (default="out")
+       Directed graphs only.
+       Use "in"- or "out"-neighbors of source node.
+
+    target : string ("in"|"out"|"in+out"), optional (default="out")
+       Directed graphs only.
+       Use "in"- or "out"-degree for target node.
+
+    nodes : list or iterable, optional (default=G.nodes)
+        Compute neighbor degree only for specified nodes.
+
+    weight : string or None, optional (default=None)
+       The edge attribute that holds the numerical value used as a weight.
+       If None, then each edge has weight 1.
+
+    Returns
+    -------
+    d: dict
+       A dictionary keyed by node to the average degree of its neighbors.
+
+    Raises
+    ------
+    NetworkXError
+        If either `source` or `target` are not one of 'in', 'out', or 'in+out'.
+        If either `source` or `target` is passed for an undirected graph.
+
+    Examples
+    --------
+    >>> G = nx.path_graph(4)
+    >>> G.edges[0, 1]["weight"] = 5
+    >>> G.edges[2, 3]["weight"] = 3
+
+    >>> nx.average_neighbor_degree(G)

+    {0: 2.0, 1: 1.1666666666666667, 2: 1.25, 3: 2.0}
+
+    >>> G = nx.DiGraph()
+    >>> nx.add_path(G, [0, 1, 2, 3])

+def equitable_color(G, num_colors):
+    """Provides an equitable coloring for nodes of `G`.
+
+    Attempts to color a graph using `num_colors` colors, where no neighbors of
+    a node can have same color as the node itself and the number of nodes with
+    each color differ by at most 1. `num_colors` must be greater than the
+    maximum degree of `G`. The algorithm is described in [1]_ and has
+    complexity O(num_colors * n**2).
+
+    Parameters
+    ----------
+    G : networkX graph
+       The nodes of this graph will be colored.
+
+    num_colors : number of colors to use
+       This number must be at least one more than the maximum degree of nodes
+       in the graph.
+
+    Returns
+    -------
+    A dictionary with keys representing nodes and values representing
+    corresponding coloring.
+
+    Examples
+    --------
+    >>> G = nx.cycle_graph(4)
+    >>> nx.coloring.equitable_color(G, num_colors=3)  # doctest: +SKIP
+    {0: 2, 1: 1, 2: 2, 3: 0}
+
+    Raises
+    ------
+    NetworkXAlgorithmError
+        If `num_colors` is not at least the maximum degree of the graph `G`
