In Jupyter Notebook, I tried to pass a large amount of data (about 2.3 GB) to Statsmodels's KDEUnivariate.fit (https://www.statsmodels.org/dev/generated/statsmodels.nonparametric.kde.KDEUnivariate.fit.html#statsmodels.nonparametric.kde.KDEUnivariate.fit) with kernel='cos'. In the Notebook, I got a MemoryError exception and traceback (which unfortunately I have since lost). In the terminal where I was running the Jupyter server, the Python 3.7 kernel spat out: Python(86244,0x7fff91104380) malloc: *** mach_vm_map(size=465845322670080) failed (error code=3) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug The MemoryError coming up in the Notebook interface is the correct behavior, but I wanted to bring to your attention that the malloc junk on stderr happens even outside of Python's tests. I'm on macOS 10.13.5. ---------- components: +macOS nosy: +William.Schwartz versions: +Python 3.7 -Python 3.1 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue5614> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
