Hi, I am a complete newbie with this software and after nearly a week now of trying to install prediction incubating and its dependencies I have finally got to the stage where I can see the ‘pio status’
However, I now get an error when running ‘pio train’ [INFO] [Engine] Datasource params: (,DataSourceParams(MyTestApp,None)) [INFO] [Engine] Extracting preparator params... [INFO] [Engine] Preparator params: (,Empty) [INFO] [Engine] Extracting serving params...

My pio status result is as follows root@server1 [/MyTest]# pio status [INFO] [Console$] Inspecting PredictionIO...
