Upgrading fails due to attribute error

[Ben Fogelson]

Hello! I'm trying to upgrade from 0.5.3 to 0.7.4. Exporting works, but when I run "smt upgrade" I get the following error:

  File "/Users/fogelson/git/stressfibermodels/newenv/bin/smt", line 31, in <module>

    main(sys.argv[2:])

  File "/Users/fogelson/git/stressfibermodels/newenv/lib/python2.7/site-packages/sumatra/commands.py", line 630, in upgrade

    project.record_store.import_(project.name, f.read())

  File "/Users/fogelson/git/stressfibermodels/newenv/lib/python2.7/site-packages/sumatra/recordstore/base.py", line 77, in import_

    records = serialization.decode_records(content)

  File "/Users/fogelson/git/stressfibermodels/newenv/lib/python2.7/site-packages/sumatra/recordstore/serialization.py", line 161, in decode_records

    return [build_record(data) for data in json.loads(content)]

  File "/Users/fogelson/git/stressfibermodels/newenv/lib/python2.7/site-packages/sumatra/recordstore/serialization.py", line 87, in build_record

    parameter_set = getattr(parameters, pdata["type"])(pdata["content"])

AttributeError: 'module' object has no attribute 'unicode'

If anyone has an idea about how to fix this, I'd really appreciate it.

Thanks,

Ben

Dear Ben,

I'm very sorry not to have replied to this much earlier. Due to pressure of other commitments, I've had little time to dedicate to Sumatra in the last 12 months, although that is now changing.

Did you resolve this problem?

Regards,

Andrew
