In this case an iterator can shrink +in size. Because the total size of an iterator is limited, the iterator +may be too large before these calls. In this case its size will be set to ``-1`` +and an error issued not at construction time but when removing the multi +index, setting the iterator range, or getting the next function. + +This has no effect on currently working code, but highlights the necessity +of checking for an error return if these conditions can occur. In most +cases the arrays being iterated are as large as the iterator so that such +a problem cannot occur. + +Optional reduced verbosity for np.distutils +------------------------------------------- +Set ``numpy.distutils.system_info.system_info.verbosity = 0`` and then +calls to ``numpy.distutils.system_info.get_info('blas_opt')`` will not +print anything on the output. This is mostly for other packages using +numpy.distutils. + +Deprecations +============ + +C-API +----- + +The utility function npy_PyFile_Dup and npy_PyFile_DupClose are broken by the +internal buffering python 3 applies to its file objects. +To fix this two new functions npy_PyFile_Dup2 and npy_PyFile_DupClose2 are +declared in npy_3kcompat.h and the old functions are deprecated. +Due to the fragile nature of these functions it is recommended to instead use +the python API when possible. |
