Overview

Sampyl

May 29, 2018: version 0.3

Sampyl is a package for sampling from probability distributions using MCMC methods. Similar to PyMC3 using theano to compute gradients, Sampyl uses autograd to compute gradients. However, you are free to write your own gradient functions, autograd is not necessary. This project was started as a way to use MCMC samplers by defining models purely with Python and numpy.

Sampyl includes these samplers currently:

Metropolis-Hastings
Hamiltonian
NUTS
Slice

For each sampler, you pass in a function that calculates the log probability of the distribution you wish to sample from. For the Hamiltonian and NUTS samplers, gradient log probability functions are also required. If autograd is installed, the gradients are calculated automatically. Otherwise, the samplers accept gradient log-p functions which can be used whether autograd is installed or not.

It is still under active development with more features coming soon!

Dependencies

Works for Python 2 or 3.

Currently, numpy and scipy are the only dependencies. To use the automatic gradient log-P capabilities, you will need to install autograd.

Installation

Unfortunately, there was a name collision, so use this to install from PyPI:

pip install sampyl-mcmc

Documentation

You can find the documentation at http://mcleonard.github.io/sampyl/. It is a work in progress, of course, but we'll cover all the important bits soon enough.

Tests

Tests are written for use with pytest, in the tests folder.

Comments

Add ability of logp to return both log posterior and its gradient

There are situations where we have access to an analytic form of both the log posterior and its gradient. It is beneficial to use this, as autograd might not work (e.g. compiled code), or it's just wasteful to calculate both logp and its partial derivatives separately. Methods like e.g. fmin_l_bfgs_b allow one to provide a function that returns both the cost function and its gradient, or a function that only returns the cost function (with the gradient in their case calculated by finite differences).

discrete_uniform broken by autograd 1.1.3

Hi, thanks for the interesting library!

I was playing with the German Tank Problem example, and initially had trouble getting it to work - it would throw "TypeError: data type not understood" while computing the logp.

This turns out to only be a problem when using autograd 1.1.3 - the previous version 1.1.2 works fine. It happens because autograd now wraps numpy.int_ as a new function, which breaks the integral type check in discrete_uniform: if x.dtype != np.int_: because it is not checking against the real np.int_.

Currently it appears that discrete_uniform is only used by the tank example.

I am inclined to think that if autograd is going to wrap np.int_ then it should also make it work transparently in the numpy type hierarchy, but I don't know enough about numpy internals to know how that might be done.

A possible workaround is to replace the check with if x.dtype.kind in "iu":. I guess another is to use the unwrapped numpy to get access to numpy.int_, although it might be confusing to have two references to numpy which are not safely interchangeable.

Sampling in parallel

There needs to be functionality to run multiple chains in parallel. This can be used for convergence testing and for increasing the samples per second you get.

v1.21.0

NumPy 1.21.0 Release Notes

The NumPy 1.21.0 release highlights are

continued SIMD work covering more functions and platforms,

initial work on the new dtype infrastructure and casting,

universal2 wheels for Python 3.8 and Python 3.9 on Mac,

improved documentation,

improved annotations,

new PCG64DXSM bitgenerator for random numbers.

In addition there are the usual large number of bug fixes and other improvements.

The Python versions supported for this release are 3.7-3.9. Official support for Python 3.10 will be added when it is released.

:warning: Warning: there are unresolved problems compiling NumPy 1.21.0 with gcc-11.1 .

Optimization level -O3 results in many wrong warnings when running the tests.

On some hardware NumPy will hang in an infinite loop.

New functions

Add PCG64DXSM BitGenerator

Uses of the PCG64 BitGenerator in a massively-parallel context have been shown to have statistical weaknesses that were not apparent at the first release in numpy 1.17. Most users will never observe this weakness and are safe to continue to use PCG64. We have introduced a new PCG64DXSM BitGenerator that will eventually become the new default BitGenerator implementation used by default_rng in future releases. PCG64DXSM solves the statistical weakness while preserving the performance and the features of PCG64.

See upgrading-pcg64 for more details.

Expired deprecations

The shape argument numpy.unravel_index cannot be passed as dims keyword argument anymore. (Was deprecated in NumPy 1.16.)

Added a simple component-wise and random direction slice sampler that implements stepping out and doubling. See demo in examples/slice_sample.py.

I also modified the State class and added a class function fromvector(self, vec) and a static function init_fromvector(vec, state) that convert between numpy arrays and State objects.

Issue 12 combo logp

I added a model class that bundles together the logp and grad_logp functions. This makes it easier to write samplers because now you can just do self.model.logp(state) or self.model.grad(state). It also contains caches for logp and grad values. There are two different model classes. One expects separate functions, the other expects one function that returns the gradient also. When a logp function also returns the gradient, you can indicate this when initializing a sampler with grad_logp=True, the second model will be used, but the subsequent behavior is completely the same.

Bump numpy from 1.9.2 to 1.22.0




Bumps numpy from 1.9.2 to 1.22.0.

Release notes
Sourced from numpy's releases.

v1.22.0
NumPy 1.22.0 Release Notes
NumPy 1.22.0 is a big release featuring the work of 153 contributors
spread over 609 pull requests. There have been many improvements,
highlights are:

Annotations of the main namespace are essentially complete. Upstream
is a moving target, so there will likely be further improvements,
but the major work is done. This is probably the most user visible
enhancement in this release.
A preliminary version of the proposed Array-API is provided. This is
a step in creating a standard collection of functions that can be
used across application such as CuPy and JAX.
NumPy now has a DLPack backend. DLPack provides a common interchange
format for array (tensor) data.
New methods for quantile, percentile, and related functions. The
new methods provide a complete set of the methods commonly found in
the literature.
A new configurable allocator for use by downstream projects.

These are in addition to the ongoing work to provide SIMD support for
commonly used functions, improvements to F2PY, and better documentation.
The Python versions supported in this release are 3.8-3.10, Python 3.7
has been dropped. Note that 32 bit wheels are only provided for Python
3.8 and 3.9 on Windows, all other wheels are 64 bits on account of
Ubuntu, Fedora, and other Linux distributions dropping 32 bit support.
All 64 bit wheels are also linked with 64 bit integer OpenBLAS, which should fix
the occasional problems encountered by folks using truly huge arrays.
Expired deprecations
Deprecated numeric style dtype strings have been removed
Using the strings "Bytes0", "Datetime64", "Str0", "Uint32",
and "Uint64" as a dtype will now raise a TypeError.
(gh-19539)
Expired deprecations for loads, ndfromtxt, and mafromtxt in npyio
numpy.loads was deprecated in v1.15, with the recommendation that
users use pickle.loads instead. ndfromtxt and mafromtxt were both
deprecated in v1.17 - users should use numpy.genfromtxt instead with
the appropriate value for the usemask parameter.

Bump py from 1.4.30 to 1.10.0




Bumps py from 1.4.30 to 1.10.0.

Changelog
Sourced from py's changelog.

1.10.0 (2020-12-12)

Fix a regular expression DoS vulnerability in the py.path.svnwc SVN blame functionality (CVE-2020-29651)
Update vendored apipkg: 1.4 => 1.5
Update vendored iniconfig: 1.0.0 => 1.1.1

1.9.0 (2020-06-24)


Add type annotation stubs for the following modules:

py.error
py.iniconfig
py.path (not including SVN paths)
py.io
py.xml

There are no plans to type other modules at this time.
The type annotations are provided in external .pyi files, not inline in the
code, and may therefore contain small errors or omissions. If you use py
in conjunction with a type checker, and encounter any type errors you believe
should be accepted, please report it in an issue.


1.8.2 (2020-06-15)

On Windows, py.path.locals which differ only in case now have the same
Python hash value. Previously, such paths were considered equal but had
different hashes, which is not allowed and breaks the assumptions made by
dicts, sets and other users of hashes.

1.8.1 (2019-12-27)


Handle FileNotFoundError when trying to import pathlib in path.common
on Python 3.4 (#207).


py.path.local.samefile now works correctly in Python 3 on Windows when dealing with symlinks.


1.8.0 (2019-02-21)


add "importlib" pyimport mode for python3.5+, allowing unimportable test suites
to contain identically named modules.


fix LocalPath.as_cwd() not calling os.chdir() with None, when
being invoked from a non-existing directory.
