Generator[T_JSON_DICT, T_JSON_DICT, Tuple[GPUInfo, str, str, str]]

A tuple with the following items: 0. gpu - Information about the GPUs on the system. 1. modelName - A platform-dependent description of the model of the machine. On Mac OS, this is, for example, 'MacBookPro'. Will be the empty string if not supported. 2. modelVersion - A platform-dependent description of the version of the machine. On Mac OS, this is, for example, '10.1'. Will be the empty string if not supported. 3. commandLine - The command line string used to launch the browser. Will be the empty string if not supported.
