ModuleNotFoundError: No module named 'scrimmage' about scrimmage HOT 10 CLOSED

Hi @savasturk,
I think I have run into this issue before; at least in my case, it was an environment setup issue.
First, make sure you have installed the SCRIMMAGE python bindings: https://github.com/gtri/scrimmage/#install-scrimmage-python-bindings
Then, assuming the root directory of the scrimmage repo on your machine is ~/scrimmage/scrimmage, run the following in your terminal to add the relevant SCRIMMAGE directories to your PYTHONPATH:

    export PYTHONPATH=${HOME}/scrimmage/scrimmage/scripts:${HOME}/scrimmage/scrimmage/python:${PYTHONPATH}

Then try to run scrimmage_runner.sh or whatever script that calls generate_scenarios.py in that same terminal. If that works, you may want to add that export line to your ~/.bashrc file, or put it in the script that calls generate_scenarios.py before generate_scenarios.py is called.

@esquires and @SyllogismRXS, if there is a cleaner way to make sure Python finds these directories, feel free to chime in. This seems to work for my environment, at least. I hope it helps, @savasturk!

Thanks, I applied all of them but I am receiving error like this:

Traceback (most recent call last):
File "generate_scenarios.py", line 47, in
import scrimmage.utils as utils
File "/home/pinar/scrimmage/scrimmage/python/scrimmage/init.py", line 33, in
from scrimmage.utils import *
File "/home/pinar/scrimmage/scrimmage/python/scrimmage/utils.py", line 44, in
import google.protobuf.internal.decoder
ModuleNotFoundError: No module named 'google'
Failed to generate scenarios

then run "sudo pip install conda" and "pip install google " but couldn't solve this error.

can you post the output of

pip --version
python --version

My guess is that the pip function is installing for python3 but generate_scenarios is running python2

from scrimmage.

Output like:
pip 10.0.1
Python 3.6.3
you are right,how can I solve this probem?
Thanks a lot .

from scrimmage.

My guess is that you just need to specify pip3. To make really sure everything is the right version though, try removing your build directory and executing the following

rm CMakeCache.txt
cmake .. -DPYTHON_MIN_VERSION=3.0
make

sudo pip3 install protobuf==3.3.0 grpcio==1.2.1 #note the 3
cd /path/to/scrimmage/python
sudo pip3 install -e .  # note the 3

from scrimmage.

I tried them but when run ":~/scrimmage/scrimmage/scripts$ ./scrimmage_runner.sh -t 100 -m ../missions/straight-vs-motorschemas.xml -p 7 " in this directory, Ireceived same error. These solutions couldn't solve my error.

Perhaps if we simplify the setup we can identify the issue. Let's ignore generate_scenarios.py and scrimmage-runner.sh for a moment. Does this work?

$ python3
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import google.protobuf.internal.decoder

from scrimmage.

Yes @esquires it was work.
Output like this:

~/scrimmage/scrimmage/scripts$ python3
Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 13 2017, 12:02:49)
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

import google.protobuf.internal.decoder

from scrimmage.

Can you post the following?

which python

In build/CMakeCache.txt, the line

PYTHON_EXECUTABLE:FILEPATH=/usr/bin/python2.7

from scrimmage.

I am going to go ahead and close this. If this is still an issue feel free to re-open and we'll help to resolve your issue.
