HELLO,ALL!
When performing parallel calculations in SU2, the following error occurs:
$ parallel_computation.py -f inv_ONERAM6.cfg -n 4
Traceback (most recent call last):
File "/usr/local/bin/parallel_computation.py", line 40, in <module>
sys.path.append(os.environ['SU2_RUN'])
File "/usr/lib/python2.7/UserDict.py", line 40, in __getitem__
raise KeyError(key)
KeyError: 'SU2_RUN'

Hello,

Have you added the variable $SU2_RUN=/path/to/your/SU2/build/bin to your environment ?

In the traceback, you can see that the error appears when parallel_computation.py asks for the entry 'SU2_RUN' in os.environ. That is a mapping of the environment variables that are available to Python when you run the script. The KeyError indicates that this entry is missing, i.e. the environment variable is not defined !

If you are not sure of the path you need to set it to, you should find it in the config.log file that was created in the directory where you configured SU2 (look for "Build Configuration Summary").
