KeyError: 'COMETS_HOME'

[merveyrc]

Hi, I am using macOS(10.12.6) and spyder(Python 3.9). I'm trying to run the comets simulation with this code: my_simulation = c.comets(my_layout, my_params) but I got a Error :could not find environmental variable GUROBI_COMETS_HOME or GUROBI_HOME or COMETS_GUROBI_HOME COMETS will not work with GUROBI until this is solved.

KeyError: 'COMETS_HOME'

eventhough I set all the environment variables as specified. When I check the bash profile, I can already see the all the paths which should be included.

When I check the environment variables and their locations, they are located as follows.

COMETS_HOME /Applications/COMETS GUROBI_HOME /Library/gurobi902/mac64 GRB_LICENSE_FILE / Library/gurobi902/gurobi.lic

I also tried the suggested solution which is "import os and set os.environ['GUROBI_HOME'] then try to make a comets object again" but again I got the same error : KeyError: 'COMETS_HOME'

Here is the tutorial which I tried : https://segrelab.github.io/comets-manual/getting_started/

Hello,

Many apologies, for some reason getting environmental variables to be visible across platforms has been one of our surprisingly hardest challenges.

Did you try:

import os os.environ['COMETS_HOME'] = '/Applications/COMETS/' os.environ['GUROBI_HOME'] = '/Library/gurobi902/mac64/'

?

Thank you so much for your return. It worked but now I got an error when I try to run simulation which is "RuntimeError: COMETS simulation did not complete:JAVA could not find gurobi."

I tried do suggested solution my_simulation.set_classpath('gurobi', '/library/gurobi902/mac64/lib/gurobi.jar') and also import os.environ['GUROBI_COMETS_HOME'] = '/opt/gurobi902/mac64'

but still I couldn't solve the problem, so simulation didn't run. What should I do to run the simulation without any errors ?

[jeremymchacon]

Those two paths (/opt/... and /library/...) are not the same. I would verify where gurobi is installed and adjust the code you supplied as need be. Also, once you get os.environ['GUROBI_COMETS_HOME'] pointing at the right path, the other command probably shouldn't be necessary.

Hi! I'm also trying to follow the tutorial mentioned above and I was getting the same error. I installed cometspy into a conda environment and I do not have the application installed on my computer so I was not sure how to set the 'COMETS_HOME' variable. In the end, I set it to this

os.environ['GUROBI_HOME']="/Library/gurobi1001/macos_universal2" os.environ['GRG_LICENCE_FILE']="/Users/my-user/gurobi.lic" os.environ['GUROBI_COMETS_HOME'] ='/Users/my-user/opt/anaconda3/envs/my-env'

Now I'm getting a new error that I don't know how I should deal with:

`IndexError Traceback (most recent call last) Cell In[44], line 1 ----> 1 my_simulation = c.comets(my_layout,my_params)

Hello,

Thanks for your interest in COMETS. If I understood correctly, you have installed comestpy but not COMETS? cometspy is "just" an interface to COMETS and requires COMETS to be installed separately, at which point the COMETS_HOME variable will be added to your path. Please reach out if I misunderstood or you have more questions.

Best,

Jeremy

Thank you for the reply!

Hi! I'm also trying to follow the tutorial to run COMETS and I was getting the same error (COMETS_HOME environmental variable is not set). I installed COMETS MATLAB Toolbox in the Windows system and I didn't install the application on my computer.

Hi yqq-79

Cometspy COMETS Matlab are user interfaces for COMETS. You cannot run the without having comets installed. Please install comets first. I would recommend to use cometspy, since it has greater community of users and is better maintained. Let me know how it goes.

[yqq-79]

I see. Thank you for the reply!

hi, i am using windows and python. I've used the methods that you discussed above, but it still doesn't work.

[jeremymchacon]

Hi LanCong, sorry you are having trouble. It looks like you have a line which is pointing to a non-existent path. Is this path correct?

os.environ ['GUROBI_HOME']='C:\gurobi1101\win64'

if yes, then replace your last environ line with this:

os.environ ['GUROBI_COMETS_HOME']='C:\gurobi1101\win64'

hi, i am using windows and python. I've used the methods that you discussed above, but it still doesn't work.

I had the same issue and solved it by downgrading to Gurobi 10.0.3 (see https://github.com/segrelab/comets/issues/52). Seems like it's an issue with Gurobi 11.0.x. Hope this helps :)

[dukovski]

Thank you Christine, I will release a new version of COMETS with an update for the latest versions of GUROBI.
