  • The name of files in a dataset consists of letters, digits, hyphens (-), and underscores (_), and the file name extension is CSV.
  • The files are saved in CSV format. Use newline characters (\n or LF) to separate lines and commas (,) to separate columns of the file content. The file content cannot contain Chinese characters. The column content cannot contain special characters such as commas (,) and newline characters. The quotation marks are not supported. It is recommended that the column content consist of letters and digits.
  • The number of columns in the training data must be the same, and the total number of data records must be greater than or equal to 100. The training columns cannot contain the data of the timestamp format (such as yy-mm-dd and yyyy-mm-dd). The training data CSV file cannot contain the table header. Otherwise, the training fails.
