説明
Hi, I got some questions about the usage of negative_feedback_sampler, my codes are as below:
from recommenders.datasets.pandas_df_utils import negative_feedback_sampler
df_feature = negative_feedback_sampler(df_feature_ori,col_user='userid',col_item='sku',col_label='label',ratio_neg_per_user=1)
df_feature_ori has about 623k rows, and 24 columns, but it really takes so long to process the negative_feedback_sampler, I wonder if I do it wrong or it's just normal situation. Any advice would be appreciated.
