Missing model_size

[matigekunstintelligentie]

When I run the following command in the 'experiment' folder python evaluate_model.py ../../pmlb/datasets/503_wind/503_wind.tsv.gz -ml myalg -results_path ../results_blackbox/503_wind/ -seed 16850 -target_noise 0.0 -feature_noise 0.0 I except a .json with a field called 'model_size' instead I do get a 'simplicity' field.

After collating these results, they are incompatible with the blackbox_results.ipynb script because all values in the model_size field are NaN

It can be fixed by adding:

from metrics.evaluation import simplicity, complexity @l23 results['model_size'] = complexity(results['symbolic_model'], feature_names) @l223 in experiments/evaluate_model.py

And: `def complexity(pred_model, feature_names): local_dict = {f:sp.Symbol(f) for f in feature_names} sp_model = get_symbolic_model(pred_model, local_dict)

compute num. components

num_components = 0
for _ in sp.preorder_traversal(sp_model):
    num_components += 1
return num_components

` @l68 in experiment/metrics/evaluation.py

what version are you running?

[matigekunstintelligentie]

@lacava I believe I pulled the latest version. The blackbox_results.ipynb hasn't changed and I can't find 'model_size' anywhere if I search it here on the github

[lacava]

got it. your best bet if you want to reproduce the paper results is to use v2.0 release. the postprocessing notebooks have not been updated since we made changes to evaluation based on the competition. in v2.0 evaluate_model.py stores model_size here
