File /usr/local/lib/python2.7/dist-packages/gurobipy/__init__.py includes the command

"from .gurobipy import *". Is the '.' before gurobipy normal?

Cause always im getting the error

File "/usr/local/lib/python2.7/dist-packages/gurobipy/__init__.py", line 1, in <module>
from .gurobipy import *
ImportError: libgurobi91.so: cannot open shared object file: No such file or directory

Thank you in advance.

  Hi Anastasios, 

  Are you using a Linux machine? Have you checked our How do I use Gurobi with PyCharm (Section: Note for Linux users) article or the Software Installation Guide (for Linux)? You likely need to extend the environment variable \(\texttt{LD_LIBRARY_PATH}\) to include the \(\texttt{lib}\) subdirectory of your Gurobi installation directory. For example, you might need to add the following to to your \(\texttt{.bashrc}\) file if you are using \(\texttt{bash}\):

  export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"

  
  Best regards,

  Maliheh

  Thank you for the response.

  Yes its a Linux system. In the .bashrc file I have included the following,

  export GUROBI_HOME="/home/user/gurobi811/linux64"
  export PATH="${PATH}:${GUROBI_HOME}/bin"
  export LD_LIBRARY_PATH="${GUROBI_HOME}/lib"
  export GRB_LICENSE_FILE="/home/user/gurobi.lic"

  Same issue again.

  Thanks and regards.

  Thanks for the further information. 

  It looks like you have a version mismatch here:

  The error is :

  ImportError: libgurobi91.so: cannot open shared object file: No such file or directory

  But your path is to Gurobi 8.1.1 not 9.1.x:

  export GUROBI_HOME="/home/user/gurobi811/linux64"
