AttributeError: type object pandas._TSObject has no attribute __reduce_cython__

[isanmu]

Problem description

First
With pandas(0.23.4) imported, I use pyinstaller 3.3.1 to package my program, when open the .exe program, it reminded me error message as bellow and self-closing then.
" File "pandas\_libs\tslibs\conversion.pyx", line 222, in init pandas._libs.tslibs.conversion AttributeError: type object pandas._TSObject has no attribute __reduce_cython__"

Second
When i changed the pandas(0.23.4) to pandas(0.20.3), the issue can be solved, but i prefer to the new features of pandas's new version, so how can i solve this issue with pandas(0.23.4)? Waiting for your reply, thanks!

How'd you install pandas? Do you have a log of the pip or conda install?

when open the .exe program

What program? Pandas or your own?

2. The program is my own project that used pandas.

I think there is an issue with pandas and pyinstaller 3.3 which was resolved in their 3.4 version. You can try upgrading to that if that's an option. Otherwise can you see if this SO answer helps?

Closing as issue is related to third party executable-creation tool

@WillAyd
Thanks for your reply!

1. Your first recommend is worked! I can open my program normally now.
2. Your second recommend have been tried before, but didn't work.

I still confused why pandas(0.20.3) can work with Pyinstaller(3.3.1) normally...

In a word, thanks for your recommends!

It looks like it started with some of the changes in 0.21.0. You can read up on it on the PyInstaller site if you want as it was discussed at length there. Here's the PR which fixed it as a starting point:
