I have a dashboard that uses the time series forecast from Splunk Machine Learning Toolkit. Until few weeks ago we were using it with Splunk 8.0.2 and ML Toolkit version 5.2.1 and it was working fine. After upgrading to Splunk 8.2.4 the "predict" command is returning the following error:
External search command 'predict' returned error code 1. .
I also tried to upgrade the ML Toolkit to version 5.3.1 which states to be compatible with Splunk 8.2.4 and with Python3 (I suppose this is the issue) but the error still occurs.
