ortools DLL load failed using PyInstaller #2552

Closed Westlife1002 closed 2 years ago

Westlife1002 commented 3 years ago

I am using pyinstaller to pack my model as a exe file. after installation, the exe is running ok on my own computer. However, when change to another computer and click the exe, it pops up:

and by looking at the command line, the reported issue is about missing pywrpcp.py

File "ortools\constraint_solver\pywrapcp.py", line 13, in <module>

Does this "other" computer have the VS redistributable ? My guess is pyinstaller won't pack system dll so you have to install it manually first

Yes, I am now downloading from here: https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

how to check if any machine is installed with VS redistributable?

I remember I packed the same model 3 years ago using pyinstaller, and run the exe on the machine without VS redistributable successfully. Are there any changes in ortools which is now very dependent on VS redistributable?

Yes, I am now downloading from here: (please let me know if it is wrong. the file is very big to download and install) https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0 show I install Visual Studio 2019 or Visual Studio Code?

No. OR-tools always required redistributables. Now, the visual studio version has changed.

both are IDE, here you just need some C++ runtime libraries so you need the Visual Studio 2019 REDISTRIBUTABLE. note: when installing Visual Studio 2019 you have a option to also install the redistributable as an internal component for C++ dev.

what do you mean by internal component ? what's the benefits having it?
