raise KeyError(key) from None KeyError: 'RANK'

我在运行vatex部分的training命令，得到了这样的错误，我上网查了下，手动给os.environ['RANK‘]赋值可跳过此错误，但是后面会报错：os.environ['WORLD_SIZE'] key error， 我思考这个问题应该不简单，搞不懂了，请各位大神教我，如何把程序跑通是第一步。。谢谢

hello!, 请问您跑通过了吗？解决问题了吗

我在探索多GPU训练。关于这个“RANK”和“WORLD_SIZE”，我能说的就是这是多GPU训练所必需的两个参数；
一般都是以下这样的源代码：

    if 'RANK' in os.environ and 'WORLD_SIZE' in os.environ:
        args.rank = int(os.environ["RANK"])
        args.world_size = int(os.environ['WORLD_SIZE'])
        args.gpu = int(os.environ['LOCAL_RANK'])
    elif 'SLURM_PROCID' in os.environ:
        args.rank = int(os.environ['SLURM_PROCID'])
        args.gpu = args.rank % torch.cuda.device_count()
    else:
        print('Not using distributed mode')
        args.distributed = False
        return

我也只能提供这点线索了（笑哭）就是在找怎么解决环境变量没有这两个key才搜到你们的
