how can I update scipy in winpython on windows?

Question

I have winpython installed and I would like to update scipy to the version 0.14. How can I do that? Should I reinstall winpython completely?

EDIT:

If I run pip install --upgrade scipy from the WinPython Command Prompt I receive this error:

Answer 1

Christoph Gohlke now provides wheels, so starting Winpython of January 2015, you may also be able to do that:

• Download the correct .whl file for your Python version (e.g. cp33 for Python 3.3 and win32 for 32-Bit) to some location, e.g. D:\scipy\
• Launch the WinPython Command Prompt

• Type

  pip install --no-index --upgrade D:\scipy\scipy‑0.15.0‑cp33‑none‑win32.whl
  

It should give you an output like this, for example for Python 3.3 32-Bit:

D:\result_tests\WinPython-32bit-3.3.5.5_build5\python-3.3.5>pip install --no-index --upgrade D:\here_is_scip\scipy-0.15.0-cp33-none-win32.whl

    Uninstalling scipy-0.14.1:

Successfully installed scipy-0.15.0

I think the error is caused because you are not running the prompt with administrator privileges. Locate the DOS-like "command prompt" program, then right-click on it and choose "run as administrator".
