However, before it fails it writes a .csv file that tells us why: none of the measurements are successful! I'm seeing lots of TOR/CANT_ATTACH errors in that file. There's something wrong in your measurement setup. If you fix that, you'll be able to visualize the results. (We should still fix the bug and produce a nicer error message.) > Then for another onionperf run (attached as 'onionperf-44028.json.xz') it > gave me a different error: > > $ onionperf visualize --data onionperf.analysis.json.xz "Test Measurements" > 2020-11-03 15:50:03 1604411403.946028 [onionperf] [INFO] loading analysis > results from /user/tmp/onionperf/analysis/onionperf.analysis.json.xz > 2020-11-03 15:50:03 1604411403.976088 [onionperf] [INFO] done! > Traceback (most recent call last): > File "/user/.local/bin/onionperf", line 4, in <module> > __import__('pkg_resources').run_script('OnionPerf==0.8', 'onionperf') > File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line > 650, in run_script > self.require(requires)[0].run_script(script_name, ns) > File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line > 1453, in run_script > exec(script_code, namespace, namespace) > File > "/user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/EGG-INFO/scripts/onionperf", > line 622, in <module> > File > "/user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/EGG-INFO/scripts/onionperf", > line 382, in main > File > "/user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/EGG-INFO/scripts/onionperf", > line 522, in visualize > File > "/user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/onionperf/visualization.py", > line 38, in plot_all > File > "/user/.local/lib/python3.8/site-packages/OnionPerf-0.8-py3.8.egg/onionperf/visualization.py", > line 129, in __extract_data_frame > KeyError: '44028' > > Because of the two errors above I'm unable to proceed with producing any > results. Any idea what I might be doing wrong? Is there any other data > you might need to help me with this? In this case it's failing even before writing a CSV file. Still, when looking at the .xz file I'm seeing only errors, too, so it's a related issue here. > Thanks a lot! > > [0]: > https://trac.torproject.org/projects/tor/wiki/org/roadmaps/CoreTor/PerformanceExperiments > https://gitlab.torproject.org/tpo/core/tor/-/issues/40157 Hope this helps!
