Hi,

 

I was trying the command from gurobipy import * in JupyterLab, but it showed the following message

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-63cdd5112d6e> in <module>
----> 1 from gurobipy import *

D:\Anaconda2\envs\py3\lib\site-packages\gurobipy\__init__.py in <module>
----> 1 from .gurobipy import *

ImportError: DLL load failed: 找不到指定的模块。

Then I tried it in command line and spyder. This import works. I tried to output sys.executable and sys.path for JupyterLab and command line. They are identical. 

I was wondering why it works for spyder and command line, but does not work in jupyterlab and jupyter notebook.

 

Thanks,

Wenyu

  Are you using the same conda environment for Jupyter, Spyder and the command line? It appears that there is an issue with the library path.

  Can you try to re-install Jupyter in your environment?
