Hi! In order to deserialize bytes object, we use pickle.loads(): import pickle import numpy as np pickle.loads(np.float64(0.34103)) and the expected result is like below (because np.float64(0.34103) is not bytes objects, appropriate errors are expected) --------------------------------------------------------------------------- UnpicklingError Traceback (most recent call last) <ipython-input-19-5c07606a60f1> in <module> ----> 1 pickle.loads(np.float64(0.34103)) UnpicklingError: invalid load key, '\xc1'. Here we have some questions that some numbers (it is rare) like 0.34104 prints the following result without errors. pickle.loads(np.float64(0.34104)) => True This occurs only when the converted bytes start with b'\x88 (for example 0.04263, 0.08526, 0.11651 ...) np.float64(0.34104).tobytes() => b'\x88.\xa8o\x99\xd3\xd5?' Can anyone answer whether this issue is Python bugs? Any answer will be highly appreciated. ---------- components: Library (Lib) messages: 379750 nosy: hyoxt121 priority: normal severity: normal status: open title: Question about deserializing some numbers (bug??) versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42168> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
