classnumpy.lib.NumpyVersion(vstring)

[source]

#

Parse and compare numpy version strings.

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.

Parameters:vstringstrNumPy version string (np.__version__).
