P ±d ã @ s$ d Z ddlZdgZG dd dZdS )a Utility to compare (NumPy) version strings.
|
|
The NumpyVersion class allows properly comparing numpy version strings.
|
The LooseVersion and StrictVersion classes that distutils provides don't
|
work; they don't recognize anything like alpha/beta/rc/dev versions.

|
|
NumPy has the following versioning scheme (numbers given are examples; they
|
can be > 9 in principle):
|
|
- Released version: '1.8.0', '1.8.1', etc.
|
- Alpha: '1.8.0a1', '1.8.0a2', etc.
|
- Beta: '1.8.0b1', '1.8.0b2', etc.
|
- Release candidates: '1.8.0rc1', '1.8.0rc2', etc.
|
- Development versions: '1.8.0.dev-f1234afa' (git commit hash appended)
|
- Development versions after a1: '1.8.0a1.dev-f1234afa',
|
'1.8.0b2.dev-f1234afa',
|
'1.8.1rc1.dev-f1234afa', etc.
|
- Development versions (no git hash available): '1.8.0.dev-Unknown'
|
|
Comparing needs to be done against a valid version string or other
|
`NumpyVersion` instance. Note that all development versions of the same
|
(pre-)release compare equal.

.. versionadded:: 1.9.0

Parameters
|
----------
|
vstring : str
|
NumPy version string (``np.__version__``).
|
|
Examples
|
--------
|
>>> from numpy.lib import NumpyVersion
|
>>> if NumpyVersion(np.__version__) < '1.7.0':
|
... print('skip')
|
>>> # skip
|
|
>>> NumpyVersion('1.7') # raises ValueError, add ".0"
|
Traceback (most recent call last):
|
...
