TypeError in datamodels/model_base.py

[gkanarek]

Tried to save an asdf file, and got this:

  File "/Users/gkanarek/miniconda3/envs/nirspecref/lib/python3.5/site-packages/jwst-0.13.0a0.dev146+g4abefa32-py3.5-macosx-10.6-x86_64.egg/jwst/datamodels/model_base.py", line 550, in to_asdf
    inline_threshold=inline_threshold).write_to(init, *args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'inline_threshold'

check what version of asdf you are using, but I also see this: asdf-format/asdf#610 cc: @drdavella @nden

You can see it in the "file" part of the traceback: jwst-0.13.0a0.dev146.

Should I roll back to 0.12.3?

[drdavella]

@gkanarek I think you need to update asdf in your environment. You can probably just do pip install --upgrade asdf.

[drdavella]

Er, actually, that's not quite right. But there is a mismatch between the asdf and jwst versions in your environment. Are you trying to run jwst from a particular release, or do you have a dev version installed in your environment? If the latter, you might need to pull down the latest master.

@gkanarek As @drdavella mentioned there's a version mismatch. It looks like you are running conda dev but have not updated recently. If this is not on purpose you can update your environment and this should fix the issue. You should get jwst version 0.13.0b.devxxx.

Please post if you are actually trying to stay with an old version of the pipeline.

@gkanarek Was this resolved? Can we close the ticket?

Closing. Reopen if this is still a problem.
