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__``).
