Machine Learning/Query Optimization example TypeError: logger() got an unexpected keyword argument 'curr_min_score'

[llermaly]

Hello, I'm trying to run the optimization query of the Machine Learning/Query Optimization example and I'm getting this error:

Using configuration
 - metric: {
  "mean_reciprocal_rank": {
    "k": 100,
    "relevant_rating_threshold": 1
  }
}
 - selected method: bayesian
 - default params: {}

TypeError: logger() got an unexpected keyword argument 'curr_min_score'

real	0m0.988s
user	0m0.927s
sys	0m0.271s

This is the method that failes

    def logger(iteration, total_iterations, score, _, duration, params):
        print(f"   - iteration {iteration}/{total_iterations} ({duration:.04f}s) scored {score:.04f} with: {json.dumps(params)}")

If I replace the "_" with curr_min_score then throws a different error:

 - iteration 39/75 (0.0159s) scored 1.0000 with: {"tie_breaker": 0.5699173276454137, "title.english|boost": 4.3273304062411615, "title|boost": 1.6393208127999483, "category|boost": 0.9826987511047194, "category.english|boost": 9.580933015419806, "descriptors|boost": 3.503736851987736, "file_name|boost": 8.566968785271335, "vendor_name|boost": 1.757893690628294, "snippet|boost": 7.494445295285921, "snippet.english|boost": 4.513989505981226, "assetId|boost": 7.035638672539559, "operator": "OR"}

ValueError: array must not contain infs or NaNs

It fails in the iteration number 39 , and num_initial_points is set to 40 as the default , num_iterations set to 70

Any advice would be appreciated.
