Python version < 3.10 #169

Open EmiFej opened 2 years ago

When converting model results to the IAMC format, the openENTRANCE iso_mapping did not convert ISO codes into full country names. Example: "GR" did not translate into "Greece" but rather it gave an error 

File "/Users/emirfejzic/opt/miniconda3/envs/IAMC/lib/python3.10/site-packages/pandas/core/indexes/multi.py", line 418, in _verify_integrity
    raise ValueError(
ValueError: Level values must be unique: [nan, nan, nan, nan, nan,....] on level 2

Installing Python 3.9 in another environment solved this issue.

Thanks for reporting this issue, @EmiFej - not that Python 3.10 is not (yet) listed as a supported Python version in the Readme. Will investigate and get back to you...

Suggest adding constraint on Python version in the config.yml or requirements.txt to avoid this.

FWIW, with release 1.4, pyam supports Python 3.10 (see https://github.com/IAMconsortium/pyam/releases/tag/v1.4.0). PRs to make this repository or add explicit version limitations very welcome!
