        （1） Add the missing file or directory under the path .

        （2） Pass in the program sys.path.append Add the path where the file or directory is located .

        （3） adopt pip Install the missing Library .

Every time I run , Again tmp A folder with a random name is generated under the folder .

It was found that , The data configuration file defined by yourself is missing datase_type The definition of . After fixing the problem , The original tmp File missing errors have also been fixed .
