Python Create a Mask-RCNN Model in Python for Smart Parking Systems

[falyusuf]

Homework Statement: I am trying to write a Python code to do a project about smart parking system. I want to create a Mask RCNN model to detect the vehicles in the parking slots.
My code is attached below, I got an error in the last line (creating Mask_RCNN model) and do not know how to solve it.
Any help would be greatly appreciated.

    GPU_COUNT = 1
    NUM_CLASSES = 1 + 80  # COCO dataset has 80 classes + one background class
    DETECTION_MIN_CONFIDENCE = 0.6

def get_car_boxes(boxes, class_ids):
    car_boxes = []

    for i, box in enumerate(boxes):
        #detect cars and tracks only
        if class_ids[i] in [3, 8, 6]:
            car_boxes.append(box)

    return np.array(car_boxes)

# Root directory of the project
ROOT_DIR = os.getcwd()
# Directory to save logs and trained model
#MODEL_DIR = os.path.join(ROOT_DIR, "logs")

# Local path to trained weights file
COCO_MODEL_PATH = os.path.join(ROOT_DIR, "mask_rcnn_coco.h5")

# Directory of images to run detection on
IMAGE_DIR = os.path.join(ROOT_DIR, "images")

# Create model object in inference mode.
model=maskrcnn(mode="inference", model_dir='mask_rcnn_coco.hy', config=MaskRCNNConfig())

I got the following error:

TypeError: 'module' object is not callable

Hello, thank you for sharing your code and project idea. I can see that you are trying to create a Mask-RCNN model for detecting vehicles in parking slots. This is a great use case for computer vision and machine learning. However, the error you are getting is due to a typo in your code. The correct syntax for creating a Mask-RCNN model is:

model = modellib.MaskRCNN(mode="inference", model_dir='mask_rcnn_coco.hy', config=MaskRCNNConfig())

Note that the "MaskRCNN" in the code should be "modellib.MaskRCNN". I hope this helps you to solve the error and continue with your project. Best of luck!
