Migration notes

Update code that imports from the following modules:

  • message_ix_models.report.computations → use message_ix_models.report.operator.

Code that imports from the old locations will continue to work, but will raise DeprecationWarning.

Data for MESSAGEix-Nexus (model.water) is no longer included in the PyPI distributions for message_ix_models. This reduces the package size from >20 MB to <5 MB. To automatically download and unpack these data into a local directory, use mix-models fetch MESSAGEix-Nexus.
