Submodules

pybmix.utils.combinatorials module

class pybmix.utils.combinatorials.TriangularMemoizer(first_term_multiplier, second_term_multiplier)

Bases: object

Specific class for triangular recurrence sequences of the kind s(0, 0) = s(1, 1) = 0, s(a, 0) = 0 for a > 0, s(a, b) = 0 for b > a, s(a, b) = f(a, b) * s(a - 1, b) + g(a, b) s(a - 1, b - 1).

For instance, Stirling numbers of the first kind are recovered setting f(a, b) = (a - 1) and g(a, b) = 1

add_rows(new_max_a)

class pybmix.utils.combinatorials.generalized_factorial_memoizer(sigma)

Bases: pybmix.utils.combinatorials.TriangularMemoizer

Computes the Generalized Factorial numbers and stores the results in a memoizer. The generalized factorial with parameter sigma in [0, 1) satisfy the triangular recurrence relation s(n, k) = (n - 1 - sigma * k) s(n - 1, k) + sigma * s(n - 1, k-1)

pybmix.utils.proto_utils module

pybmix.utils.proto_utils.get_field(msg, field: str)

Gets the field of an object, even if it is in a submessage

Parameters

• msg (google.protobuf.message) – a protobuf (object)

• field (str) – a field of this proto. If it is a nested field, then we adopt the syntax a joining the subfields separated by ‘.’

pybmix.utils.proto_utils.get_oneof_names(oneof_name, msg)

pybmix.utils.proto_utils.get_oneof_types(oneof_name, msg)

pybmix.utils.proto_utils.set_oneof_field(fieldname, msg, val)

Sets a ‘oneof’ field inside of ‘msg’ :param fieldname: the oneof name of the field :type fieldname: str :param msg: the protobuf to modify :type msg: google.protobuf.Message :param val: the value to set :type val: google.protobuf.Message, numeric, string

Example

>>> protomsg = pybmix.proto.hierarchy_prior_pb2.NNIGPrior()
>>> prior = pybmix.proto.hierarchy_prior_pb2.NNIGPrior.FixedValues(mean=1)
>>> set_oneof_field("prior", protomsg, prior)

pybmix.utils.proto_utils.set_shallow_field(fieldname, msg, val)
