It appears that the version number of the kwant package on the cheese-shop is incorrect. On `https://pypi.python.org/pypi/kwant/` the version is correctly stated as `1.0.0`, and the tar archive is version `1.0.0` as required, however when installing via `pip` the version is quoted as `0.1.6`. Installation procedure: - set up python virtualenv `venv` - activate virtualenv - installed all dependencies via `pip` (cython, numpy, scipy, tinyarray) - installed kwant via `pip` - launch python shell: <<< import kwant <<< print kwant.__file__ /<path redacted>/venv/local/lib/python2.7/site-packages/kwant/__init__.pyc <<< print kwant.version.version 0.1.6 The API for this package seems to be commensurate with that for version `1.0.0`, so I believe that this is just a case of `kwant/_static_version.py` having not been regenerated correctly when kwant was packaged and published on the cheese-shop. This is no a major issue, but may be confusing for people who have downloaded kwant via `pip` especially if they then seek help and quote the version as `0.1.6`. Regards Joe P.S. the non-standard Python shell prompts `<<<` were used because Gmane accuses me of top-posting if I use `>>>`
