Gurobi library cannot be loaded using the latest github-version code

[KelvinZhang99]

Hello.
Currently, I want to use the _reset() function of Gurobi.model. Therefore, I installed the latest version through pip install git+https:https://github.com/metab0t/PyOptInterface.git. The installation was successful. But when I ran the model, it appeared that
File "D:\app\miniconda3\envs\prep-shot\lib\site-packages\pyoptinterface\_src\gurobi.py", line 542, in __init__ init_default_env() File "D:\app\miniconda3\envs\prep-shot\lib\site-packages\pyoptinterface\_src\gurobi.py", line 116, in init_default_env DEFAULT_ENV = RawEnv() RuntimeError: Gurobi library is not loaded.

When I test the autoload_library() function in _src.gurobi, I found although libs=['C:\\gurobi1103\\win64\\bin\\gurobi110.dll', 'D:\\app\\miniconda3\\envs\\prep-shot\\lib\\site-packages\\gurobipy\\gurobi110.dll', 'gurobi120.dll', 'gurobi110.dll'], ret=false.

In comparison, when I directly used pip install pyoptinterface for the repository-version, this error did not show.

I have tried both on my windows and linux with the same results. Do you know how to solve it?

My gurobi version is 11.0.3, and python vesion is 3.9.23.

The latest git version requires Gurobi 12 because it implements nonlinear programming interfaces.

Thank you very much. After installation of Gurobi 12, no error appears.
