Message318364
my first time to report a bug here.
But it is so annoying, I have to report it.
Here is the demonstration of the errors I encounter:
>>> import numpy as np
>>> import pandas as pd
>>> np.__version__
'1.14.3'
>>> pd.__version__
u'0.23.0'
>>> df=pd.DataFrame({'a':range(10)})
>>> df['b']='abc'
>>> df
a b
0 0 abc
1 1 abc
2 2 abc
3 3 abc
4 4 abc
5 5 abc
6 6 abc
7 7 abc
8 8 abc
9 9 abc
>>> np.savez_compressed('abc',data=df.to_records(index=False))
>>> a=np.load('abc.npz')
>>> a.keys()
['data']
>>> a['data']
Traceback (most recent call last):
