General area which your question is related to.

• Installation of RMG
• Running an RMG job
• Using RMG API
• Arkane (formerly CanTherm)
• Dependencies
• An error message

Context

When we run a case on service we get an error message, which is "AttributeError: 'rmgpy.kinetics.arrhenius.MultiArrhenius' object has no attribute 'T0'".

I attach the files we get below
26_RR_0.01_T_0.01.zip

It includes input file, RMG.log and slurm.out file.

Question

Even though we meet this error, we still get a chem.inp. Does this error important and how will this error affect the chem.inp?

[mjohnson541]

The mechanism terminated properly and should be fine. It seems that the collision limit analysis functions can't handle all of the data formats RMG supports.

@mliu49 Hi Max. I use the basic user version RMG and I used "conda upadate rmg rmgdatabase -c rmg" to upadate my RMG. However, when I run the cases I still get this error and the RMG.log shows me that my RMG is still version 2.4.0. Is version 2.4.1 only available for the developer version?

[mliu49]

Binary versions of 2.4.1 are available for Linux and MacOS. If conda update isn't working, you can try explicitly installing it using conda install rmg=2.4.1 -c rmg. Either way, you should confirm the version using conda list rmg or python -c "import rmgpy; print rmgpy.__version__".
