Dear all,
I am pleased to announce that BayesPy 0.3 has been released.
BayesPy provides tools for variational Bayesian inference. The user can
easily constuct conjugate exponential family models from nodes and run
approximate posterior inference. BayesPy aims to be efficient and
flexible enough
Dear all,
I am pleased to announce the release of BayesPy version 0.2.
BayesPy provides tools for Bayesian inference in Python. In particular,
it implements variational message passing framework, which enables
modular and efficient way to construct models and perform approximate

Hi,
I'm trying to install NumPy 1.7.1 for Python 3.3 using
pip install numpy
However, I get the following error after a while:
error: numpy.egg-info/dependency_links.txt: Operation not supported
Is this a bug or am I doing something wrong? If it matters, I'm using
virtualenv as I do
.
But still, any help is appreciated.

I don't quite understand how einsum handles broadcasting. I get the
following error, but I don't understand why:
In [8]: import numpy as np
In [9]: A = np.arange(12).reshape((4,3))
In [10]: B = np.arange(6).reshape((3,2))
In [11]: np.einsum('ik,k...-i...', A, B)
an inner1d implemented in
numpy.core.umath_tests.inner1d
from numpy.core.umath_tests import inner1d
It should do the trick :)

Hi,
I have encountered a very weird behaviour with einsum. I try to compute
something like R*A*R', where * denotes a kind of matrix
multiplication. However, for particular shapes of R and A, the results
are extremely bad.
I compare two einsum results:
First, I compute in two einsum calls as
Hi!
How can I compute dot product (or similar multiplysum operations)
efficiently so that broadcasting is utilized?
For multi-dimensional arrays, NumPy's inner and dot functions do not
match the leading axes and use broadcasting, but instead the result has
first the leading axes of the first
Hi,
I was wondering if someone could provide some intuition on the
performance of einsum?
I have found that sometimes it is extremely efficient but sometimes it
is several orders of magnitudes slower compared to some other
approaches, for instance, using multiple dot-calls.
My intuition is that
Hi!
I was wondering if anyone could help me in finding a memory leak problem
with NumPy. My project is quite massive and I haven't been able to
construct a simple example which would reproduce the problem..
I have an iterative algorithm which should not increase the memory usage
as the iteration
Hi,
Is this a bug in numpy.einsum?
np.einsum(3, [], 2, [], [])
ValueError: If 'op_axes' or 'itershape' is not NULL in theiterator
constructor, 'oa_ndim' must be greater than zero
I think it should return 6 (i.e., 3*2).

Hi!
I was wondering whether it would be easy/possible/reasonable to have
classes for arrays that have special structure in order to use less
memory and speed up some computations?
For instance:
- symmetric matrix could be stored in almost half the memory required by
a non-symmetric matrix
