KeyError: 'COMETS_HOME' #16
Comments
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:
? |
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 but still I couldn't solve the problem, so simulation didn't run. What should I do to run the simulation without any errors ? |
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.

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 ?

Hi! os.environ['GUROBI_HOME']="/Library/gurobi1001/macos_universal2" Now I'm getting a new error that I don't know how I should deal with: `IndexError Traceback (most recent call last) File ~/opt/anaconda3/envs/dfba/lib/python3.8/site-packages/cometspy/comets.py:147, in comets.init(self, layout, parameters, relative_dir) File ~/opt/anaconda3/envs/dfba/lib/python3.8/site-packages/cometspy/comets.py:175, in comets.__build_default_classpath_pieces(self) IndexError: list index out of range` |
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

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:

Thank you for the reply! |
Hi! |
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. |
I see. Thank you for the reply! |
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.

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/
The text was updated successfully, but these errors were encountered:
