Predictive algorithm job failed with error replicas estimation failed

The error is due to the failure of the “Traffic, Capacity and Replicas Relationship Modeling” algorithm to produce a usable model, the following methods can be attempted to solve this issue:

• Try increasing the length of historical data by adjusting the algorithm job parameter --re-history-len.
• With the detailed model evaluation information returned with the error, try relaxing the model validation requirements by adjusting the algorithm job parameters --re-min-correlation-allowed and --re-max-mse-allowed. However, be aware that if the relaxed values differ too much from the default values, the accuracy of the model may be hard to guarantee.
