New submission from Alex James <ac.ja...@shaw.ca>: When using cPickle to pickle / unpickle an object instance whose __dict__ contains a dictionary of NumPy Arrays (on a windows32 system), some of the array elements have the wrong type raising a ValueError: could not convert string to float.
On UNIX platform this error does not occur, and the data is read out in the correct type every time. Forcing the caller to use pickle.py module instead removed the issue. Statements about the imprecision of cPickle (such as issue1536, 655802), or its deprecaition (now I can't find where that was mentioned), would assist. By contrast the current state of the documentation implies that cPickle is better overall, and thus should be used preferentially. ---------- assignee: georg.brandl components: Documentation, Extension Modules, Windows messages: 89418 nosy: ac.james, georg.brandl severity: normal status: open title: cPickle can misread data type type: behavior versions: Python 2.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6290> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
