【bug】 `openmvs.py` gpu_config set --cuda-device -1 or --cuda-device -2, cant use GPU

How did you install ODM? (Docker, installer, natively, ...)?

docker nodeOdm

What is the problem?

【bug】 openmvs.py gpu_config set --cuda-device -1 or --cuda-device -2, cant use GPU

config = [
                "--resolution-level %s" % int(resolution_level),
                '--dense-config-file "%s"' % densify_ini_file,
                "--max-resolution %s" % int(outputs['undist_image_max_size']),
                "--max-threads %s" % args.max_concurrency,
                "--number-views-fuse %s" % number_views_fuse,
                "--sub-resolution-levels %s" % subres_levels,
                "--archive-type 3",
                '-w "%s"' % depthmaps_dir, 
                "-v 0"
            ]

            gpu_config = []
            use_gpu = has_gpu(args)
            if use_gpu:
                gpu_config.append("--cuda-device -1")
            else:
                gpu_config.append("--cuda-device -2")

            extra_config = []

            if args.pc_skip_geometric:
                extra_config.append("--geometric-iters 0")

            masks_dir = os.path.join(tree.opensfm, "undistorted", "masks")
            masks = os.path.exists(masks_dir) and len(os.listdir(masks_dir)) > 0
            if masks:
                extra_config.append("--ignore-mask-label 0")

            with open(densify_ini_file, 'w+') as f:
                f.write("Optimize = 7\n")

            def run_densify():
                system.run('"%s" "%s" %s' % (context.omvs_densify_path, 
                                        openmvs_scene_file,
                                        ' '.join(config + gpu_config + extra_config)))

    gpu_config = []
            use_gpu = has_gpu(args)
            if use_gpu:
                gpu_config.append("--cuda-device -1")

if we has a gpu ,why --cuda-device -1 ? it should be --cuda-device 0 or --cuda-device 1

What should be the expected behavior? If this is a feature request, please describe in detail the changes you think should be made to the code, citing files and lines where changes should be made, if possible.

cause we didnot use GPu , want to use Gpu by node-odm correctly

How can we reproduce this? What steps did you do to trigger the problem? If this is an issue with processing a dataset, YOU MUST include a copy of your dataset AND task output log, uploaded on Google Drive or Dropbox (otherwise we cannot reproduce this).
