calculate_feature_matrix #5

#5 Comment: I fixed this issue by updating pandas: pip install pandas==0.24.0

es = make_ecommerce_entityset() f1 = ft.Feature(es["log"]["product_id"]) f2 = ft.Feature(es["log"]["purchased"]) f3 = ft.Feature(es["log"]["value"]) f4 = ft.Feature(es["log"]["countrycode"])

features = [f1, f2, f3, f4] ids = [0, 1, 2, 3, 4, 5] feature_matrix = ft.calculate_feature_matrix(features, es, instance_ids=ids) print(feature_matrix)

The error:

AttributeError Traceback (most recent call last)
