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. |
