no module name 'gurobipy'
回答済み
I installed Gurobipy and the license successfully. But I execute my program from Jupiter... The result is: No module named 'gurobipy' as is showed here:
--------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last) <ipython-input-1-ebd7a8b9a1e6> in <module> 2 import pandas as pd 3 import numpy as np ----> 4 from gurobipy import * ModuleNotFoundError: No module named 'gurobipy'
The license I have is:

Many thanks for your help!

You need to do one more step to use Gurobi in Jupyter.
From the Quick Start Guide:http://www.gurobi.com/documentation/8.1/quickstart_mac/py_building_and_running_th.html
> You can also install the
gurobipymodule directly into other Python environments. The steps for doing this depend on your platform. On Mac OS, you will need to open a terminal window, change your current directory to the Gurobi <installdir> (the directory that contains the file setup.py), and issue the following command:python setup.py install

Many thanks Gwyneth!!!
It's amazing... It seems that I don't have the setup.py file

To run the setup script, navigate to the directory where you installed Gurobi, such as /Library/gurobi811/mac64/
From the terminal prompt there, run the command python setup.py install.
For example:
bash-3.2$ cd /Library/gurobi811/mac64/ bash-3.2$ python setup.py install
I hope this helps.

I was on the wrong path...
running install
running build
running build_py
creating build
creating build/lib
creating build/lib/gurobipy
copying lib/python2.7/gurobipy/__init__.py -> build/lib/gurobipy
copying lib/python2.7/gurobipy/gurobipy.so -> build/lib/gurobipy
running install_lib
running install_egg_info

I believe this problem is because you may need to run the command as a super-user:
From the Quick Start Guide (http://www.gurobi.com/documentation/8.1/quickstart_mac/py_building_and_running_th.html):
python setup.py install
Unless you are using your own private Python installation, you will need to run this command as super-user.

But the module is still not found! I set up the PATH ;(

I suspect that perhaps your Jupyter is using a different Python than the one that is the default at the command line. In your Jupyter notebook, try
import sysprint(sys.executable)
print(sys.version)
print(sys.version_info)This will let you know which Python you need to use when you call the install script. For me, the output is:
/anaconda3/bin/python 3.6.8 |Anaconda, Inc.| (default, Dec 29 2018, 19:04:46) [GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] sys.version_info(major=3, minor=6, micro=8, releaselevel='final', serial=0)
So I run:
/Library/gurobi811/mac64/ $ /anaconda3/bin/python setup.py install1 -
You are using Jupyter too?
this command
import sysprint(sys.executable)
is not working for me...
0 -
import os, sys
print(sys.executable) # works this time
print(sys.version)
print(sys.version_info)You are right, I'm calling another python. Do you know if with one Jupyter we can configure more than one python...? or can i install the gurobi in this python?
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 3.7.2 (v3.7.2:9a3ffc0492, Dec 24 2018, 02:59:38) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] sys.version_info(major=3, minor=7, micro=2, releaselevel='final', serial=0)

I would install Gurobi in the python that your Jupyter uses. So, as I wrote before:
cd to where you have installed Gurobi, such as
/Library/gurobi811/mac64/and run:
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 setup.py install0 -
Ereuka!!!
Many thanks!!!!

Dear Gwyneth,
I have the same problem and I followed the instructions as you said but my cmd keeps giving me this error:
C:\gurobi900\win64>python setup.py install
running install
running build
running build_py
error: package directory 'python38\lib\gurobipy' does not existcan you advise?
Thanks.

Please see here.

I don't understand why the directions are for mac-only. The setup.py file installs perfectly fine on Windows with the same exact directions as for mac.
