        Hello,

         

        Create ML does not recognise my Core Motion (.csv) recordings. As you can see in the screenshot below, the "Model input has issues", "Training data [is] not ready" and "No feature columns [are] selected". But I am not even able to select any feature columns when I click on the "Selected Features..." button.

         

         

        My training data structure looks like this:

         

        train

        >other

        >>train1.csv

        >some

        >>train1.csv

         

         

        And my files look like this:

         

        timestamp

        acceleration_x

        acceleration_y

        acceleration_z

        attitude_pitch

        attitude_roll

        attitude_yaw

        gravity_x

        gravity_y

        gravity_z

        rotation_x

        rotation_y

        rotation_z

        I also tried the csv data without the timestamp column before. Additionally I tried different labels for the column names without success. What is the issue here? Since there are no examples or documentation for activity classifiers and Create ML it is really frustrating to solve issues like these. I also watched the WWDC 2019 session about activity classifiers with Create ML several times now, but I see no hint which helps me with my issue.

         

        Does someone have an idea?

         

         

         

         

        EDIT: Well unfortunately this forum does not support uploading images. I hope my issue has been nervetheless described precise enough.
