4 years ago Hi,
My understanding is that you need to build your program adding cplex.dll to pysinstaller data. Please have a look at here: https://stackoverflow.com/questions/38791685/how-do-i-include-dll-file-in-executable-using-pyinstaller.
The pyinstaller manual has clear instructions on how to include binaries: https://pyinstaller.readthedocs.io/en/stable/spec-files.html#adding-binary-files
Note that (DecisionOptimization team at IBM) provide support if you have problems with cplex or docplex. However, providing support for pyinstaller is out of scope, you should contact pyinstaller's support https://www.pyinstaller.org/support.html .
Thanks
Hello everyone, i used python to model and solve an optimization problem. and it works very well in jupyter. i generated an exe. (using pyinstaller filename.py). i worked well.. i put the cplex dll in the same folder as the python exe. however, when i try to run my exe..i have this error " c:\users\appdata\local\continuum\anaconda3\lib\site-packages\PyInstaller\loader\pyimod03_importers.py:623: MatplotlibDeprecationWarning: The MATPLOTLIBDATA environment variable was deprecated in Matplotlib 3.1 and will be removed in 3.3. exec(bytecode, module.dict) sys:1: DtypeWarning: Columns (6,88,115,116) have mixed types.

i dont understand why he doesn't find cplex..knowing that the jupyter code works very well. I use Docplex
Does anyone have any suggestion to solve this problem? Thank you in advance! :)
