getting error: AttributeError: 'tuple' object has no attribute 'numpy' while running yolo.inference() after loading weights

I'm trying to get prediction from preloaded weights from this repo, and get some inputs about the model.

I use yolov4-tiny-relu-tpu.cfg config & yolov4-tiny-relu.weights and v3 of this repo but while running this code:

from yolov4.tf import YOLOv4, YOLODataset, create_mAP_input_files

WORKING_DIR ="/path/to/yolov4_tf24/"

yolo = YOLOv4()

yolo.config.parse_names(WORKING_DIR + "test/coco.names")
yolo.config.parse_cfg(WORKING_DIR + "config/yolov4-tiny-relu-tpu.cfg")

yolo.make_model()
yolo.load_weights(
     WORKING_DIR + "weights/yolov4-tiny-relu.weights", weights_type="yolo"
)

yolo.summary()

yolo.inference(media_path = "/path/to/image.png",
                         is_image=True,
)

im getting this error:

the model returns array of tuples with tensors in them, and try to turn them to a numpy array. I would be happy for some help.
