DxC_ML: look up window size = 0, it should be positive is thrown when a similarity or clustering solution is trained for multiple intervals in a dayDescriptionWhen a similarity or a clustering solution is set to be trained with update frequency with intervals in a day, you can see the below error in the logs: DxC_ML: look up window size = 0, it should be positiveSteps to Reproduce Train an similarity or clustering solution with update on <choose frequency in a day>2. After the training, you can see the below error in the logs multiple times - DxC_ML: look up window size = 0, it should be positive: no thrown error" will be present multiple times in Glide logsWorkaroundThis error can be ignored and does not indicate any functionality issuesRelated Problem: PRB1396588
