Pyomo 5.2: yacc table file version is out of date

[Ted Boydston]

Greetings,

I recently updated to

Pyomo 5.2 (CPython 2.7.11 on Linux 2.6.32-642.6.2.el6.x86_64)

and am now receiving this warning:

cae_elec.none[173](0)> /programs/cae_elec/apps/anaconda_2.1.0/bin/pyomo solve --solver=glpk --solver-executable=/programs/cae_elec/apps/glpk/install/glpk_4.55/bin/glpsol license.py model.dat
[    0.00] Setting up Pyomo environment
[    0.00] Applying Pyomo preprocessing actions
[    0.01] Creating model
WARNING: yacc table file version is out of date

Is this something to be concerned about?  Is there a way to rectify this?

This warning did not appear in Pyomo 5.1.1.

For reference, I am on Red Hat Enterprise 6.6

Thanks,
Ted Boydston

It sounds like you upgraded the ply package. Try finding and deleting all copies of the "parse_table_datacmds.py" and "parse_table_datacmds.pyc" files on your system (probably found within the Pyomo installation location [site-packages/pyomo/core/data])
