EddiesObservations cannot be imported from py_eddy_tracker.observations about py-eddy-tracker

The correct command is EddyTracking yamlfile Le ven. 27 déc. 2019 à 13:03, evanmason <[email protected]> a écrit :

The Wiki needs to be updated. The section for creating a tracking recipe presently fails as follows: In [7]: from py_eddy_tracker.observations import EddiesObservations as Model --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-7-77527e386807> in <module> ----> 1 from py_eddy_tracker.observations import EddiesObservations as Model ImportError: cannot import name 'EddiesObservations' from 'py_eddy_tracker.observations' (/home/emason/VENVP3/lib/python3.7/site-packages/pyEddyTracker-3.0.0-py3.7.egg/py_eddy_tracker/observations/__init__.py) This seems to work: In [2]: from py_eddy_tracker.observations.observation import EddiesObservations as Model but I then get the following when trying to follow the Wiki: (VENVP3) ***@***.*** global4eddytracking]$ EddyTracking my_tracking.py my_tracking.yaml usage: Tool to use identification step to compute tracking [-h] [-v LOGGING_LEVEL] [--correspondance_in CORRESPONDANCE_IN] [--correspondance_out CORRESPONDANCE_OUT] [--save_correspondance_and_stop] [--blank_period BLANK_PERIOD] yaml_file Tool to use identification step to compute tracking: error: unrecognized arguments: my_tracking.yaml (VENVP3) ***@***.*** global4eddytracking]$ — You are receiving this because you are subscribed to this thread.

Ok, so the Wiki should be updated to reflect that. Is it no longer possible to add a 'tracking recipe', or is that now done within the yaml?

[evanmason]

Is it the file 'tracking.yaml' in share? That is 2 years old.

Using that I get the following error:

Two files are produced:
148 -rw-rw-r-- 1 emason emason 148224 Dec 28 17:43 Cyclonic_correspondances.nc
28 -rw-rw-r-- 1 emason emason 25888 Dec 28 17:43 Cyclonic_untracked.nc
but no Cyclonic.nc.

My yaml file contains:

#DIAGNOSTIC_TYPE: 'SLA'
#DIAGNOSTIC_TYPE: 'ADT'

PATHS:
  # Files produces with EddyIdentification
  FILES_PATTERN: /marula/emason/data/Copernicus/GLOBAL_REANALYSIS_PHY_001_030/global4eddytracking/Cyclonic_20061*.nc

So I updated all PET dependencies and that solved the issue for the missing Cyclonic.nc. I don't know which dependency was the culprit.
