pyinstaller issue with vpython

[Rick Shaffer]

 I have an issue with pyinstaller and/or vpython. I’ve tried to boil this down into the simplest code possible. Here is my python code:

import time
from vpython import *

def test2():

    while True:
        print ("Hello")
        time.sleep(2)

if __name__ == "__main__":
    test2()

When executing in the Anaconda/Spyder environment everything works as expected. However, after building a .exe with pyinstaller and executing test2.exe it fails with the following error :

Traceback (most recent call last):
File "test2.py", line 10, in <module>
File "<frozen importlib._bootstrap>", line 991, in _find_and_load
File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked

[8568] Failed to execute script test2

When I look at the path “C:\\Users\\Rick.PC-0XFZ\\Projects\\test2\\dist\\test2\\vpython\\vpython” I see “cyvector.cp38-win_amd64.pyd”, but no other files or directories. Specifically there is no “gs_version.py” file and no “vpython_libraries” directory.

Unfortunately I don’t know enough about .pyd files to understand the issue. And I’ve tried adding these directories to my sys.path but to no avail. Any suggestion or help is appreciated.

Thanks.

I know nothing about pyinstaller, but I'll comment that the vpython module most definitely does need all of the files that are in Lib/site-packages/vpython. I suppose however that (again, knowing nothing about pyinstaller) it's possible that the single pyd file does contain all of the pieces, and that something else is wrong. A very crude thing you might try is to compare the size of the vpython module and the size of the pyd file.

Bruce, thank you for the response. After a bit more finagling I did find a solution. Apparently pyinstaller is not aware of the need for the files in the vpython_libraries and vpython_data directories. So I simply added these files to the pyinstaller distribution with the "--add-data" option. Thanks again for your help.

Hi Rick, I have the same problem and I do not know how to solve it. Can you be more specific with the solution you found, please?

Hi Rick, I am stuck here. can you give the detail how to use --add-data command.
