 """Create a tileset Note: this step is refered to as "upload" in the API docs; This class's upload() method is a high-level function which acts like the Studio upload form. Returns a response object where the json() contents are an upload dict. Completion of the tileset may take several seconds or minutes depending on size of the data. The status() method of this class may be used to poll the API endpoint for tileset creation status. Parameters stage_url: str URL to resource on S3, typically provided in the response of this class's stage() method. tileset: str The id of the tileset set to be created. Username will be prefixed if not present. For example, 'my-tileset' becomes '{username}.my-tileset'. name: str A short name for the tileset that will appear in Mapbox studio. patch: bool Optional patch mode which requires a flag on the owner's account. bypass: bool Optional bypass validation mode for MBTiles which requires a flag on the owner's account. Returns ------- requests.Response """
