**Question/Issue:*I am building a system to detect faults in a particular machine. I gathered data from my ESP32-DOIT board at an interval of 5 seconds with 43 different sensors and stored the data in csv format. But when I upload the data(idle, nominal, and fault), I keep getting a data split error which is shown in the picture attached. I also noticed that only two of the csv files are categorized under training while the fault csv file is directly pushed to test. I will appreciate all the help I can get. Thanks.
**Context/Use case:Sensor Fusion
