v1.0.0 te30/run0.sh and run.sh produce no graphs

[trevorhardy]

Both run0.sh and run.sh run without error on the console but the graphing script produces an error and no graphs

what os?

[trevorhardy]

I ran the TESP installer on a VirtualBox VM with a clean installation of Ubuntu LTS 20.04.1

[trevorhardy]

Still failing for me with the same error message after logout and login.

[temcdrm]

Cannot reproduce: Ubuntu 20.0.4 LTS, Python 3.8.5, tesp_support 0.9.4

Please zip up the contents of examples/te30 and post here

[trevorhardy]

Confirmed I'm still having problems; here's the .zip te30.zip

[temcdrm]

The simulations didn't actually run to completion. gridlabd.log from December 10 indicates an empty GLPATH causing error termination, and *0.log from December 11 indicates those simulations never got started.

• When a simulation completes, none of the *metrics.json files should have 0 byte sizes; there should at least be metadata in them
• If one simulation stops due to error, the other federates can remain in a hung state. Use ps or lsof -i :5570 to see which processes are still running on FNCS, or lsof -i :23404.sh to see which processes are still running on HELICS. Scrub with ./kill5570.sh or ./kill23404.sh as needed. In FNCS, sometimes you have to use kill -9 #### on a stubborn process, where #### is the PID from ps.
• There can't be any processes listening to 5570 (FNCS) or 23404 (HELICS) before starting a new case. (Unless you manually reconfigure a case to use different ports.)

It's possible the December 10 failure was caused by the environment not being set. The December 11 failure could have been caused by stale processes left over from the day before. To retry:

• ./clean.sh
• _python3 preparecase.py
• ./run.sh

I restarted the VM (virtual power off and back on) and ran the above commands followed by python3 plots.py TE_Challenge: I still get the same error and am seeing the same empty output JSONs you referenced.

After trying the above when I look for hung processes us ps or lsof I don't see any.

> echo $GLPATH
/opt/tesp/lib/gridlabd:/opt/tesp/share/gridlabd

I've attached the lastest TE30 folder as well. te30.zip

[trevorhardy]

Resolved through restart of VM.
