NUM : missing abs in metrics evaluation

[LexABzH]

Describe the bug

In the num template, the get_and_save_metrics is missing some abs in errors evaluations.

Concerned template

• NLP template
• NUM template
• VISION template
• API template
• How templates are generated - Jinja

To Reproduce

CF. get_and_save_metrics in https://github.com/OSS-Pole-Emploi/gabarit/blob/main/gabarit/template_num/num_project/package_name/models_training/regressors/model_regressor.py

Expected behavior

abs_err should call abs function. Same for rel_err ?

Actual behavior

We can have negative values for an "absolute error" ...

Is this a regression?

That is, did this use to work the way you expected in the past?
