I get this error after 'sim.run()' code;

How can fix it? Can you help me?

[dukovski]

I think I've seen similar problem before. Can you send me the script you are trying to run? Can you run the P1_test_tube_aerobic.ipynb at all? You can get is here: https://sites.google.com/view/comets-tutorial/home

[dukovski]

I think I know what the bug is. "line_terminator" should be "lineterminator" in to_csv(f, mode='a', line_terminator = '\n', header=False, index=False) Let me change and test this.

[2132030]

My script is below:

Archive.zip

I run 'P1_test_tube_aerobic.ipynb' but got same error.

[dukovski]

OK, I think, in model.py all "line_terminator" need to be changed to "lineterminator". I will try that later today, but you may try to do it yourself and test it. Then you can actually push it here. I would appreciate that. :)

[2132030]

I changed and test it and solved this, after then I got another error in my script:

try the following:

to the location of gurobi.jar, for example:
os.environ['GUROBI_COMETS_HOME'] = '/opt/gurobi900/linux64'

[dukovski]

This seems like you don't have gurobi installed properly. Are you doing this on Linux? If yes, make sure you have the GUROBI_COMETS_HOME defined in your .bashrc file.
My .bashrc file has these lines:

export COMETS_HOME=/projectnb/cometsfba/comets_2.11.1
export PATH=$PATH:$COMETS_HOME
export GUROBI_HOME=/share/pkg.7/gurobi/9.0.0/install/
export GUROBI_COMETS_HOME=/share/pkg.7/gurobi/9.0.0/install/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$GUROBI_COMETS_HOME/lib/

export GUROBI_PATH=$GUROBI_HOME

Make sure you adapt them to your case, wherever you installed gurobi should replace my line /share/pkg.7/gurobi/9.0.0/install/
Is this enough info you need, or should I explain in more detail?

[2132030]

No, I am using MacOS

[dukovski]

On Mac you need this line:
export GUROBI_HOME=/Library/gurobi902/mac64/
Where instead of gurobi902 put gurobi, so replace the number to your version of gurobi.

[2132030]

I tried this line in .bashrc file:
export GUROBI_HOME= /Library/gurobi1100/macos_universal2

but, I got this error again:

Hi all, this is an aside, but while the lineterminator thing probably should be changed, it shouldn't cause an error I don't think. It is more likely a red herring related to other issues.

You need to make sure that you are running bash on your Mac. If you are running zsh, which is the default in latest Macs, you need to get that line in the .zshrc file. Check, do you have a .zshrc file?

[2132030]

Yes, I have .zshrc file

[2132030]

I tried in the .zshrc file but I got this error again :(

[dukovski]

Can you show me a screenshot of your gurobi path and directory contents?
What do you get when you run:
import os
os.environ['GUROBI_COMETS_HOME']

[2132030]

I got when I run:
import os
os.environ['GUROBI_COMETS_HOME']
