[jira] [Comment Edited] (LUCENE-5175) Add parameter to lower-bound
TF normalization for BM25 (for long documents)

I downloaded the luceneutils benchmark suite and the enwiki data and tried to run the out-of-the-box demo. I need to ask our sysadmins to upgrade python versions on our dev machines.

I downloaded the luceneutils benchmark suite and the enwiki data and tried to run the default out-of-the-box demo that gets copied into localrun.py and got the errors below. I suspect maybe the python version on our dev machine is old or I need to set up some env variables.
Is there anything obvious in the message below? Should I be asking questions about benchmark on the dev list or is there a separate list for that?
