OpenCV: TypeError: an integer is required (got type list)

[alcarazzam]

Environment

Python 3.7.4 ImageAI 2.1.3 opencv-python 4.1.0.25 tensorflow 1.13.1

Details

When running the following script using a custom model, ImageAI raises an error when drawing the rectangle of the recognized object.

from imageai.Detection.Custom import CustomObjectDetection

detector = CustomObjectDetection()
detector.setModelTypeAsYOLOv3()
detector.setModelPath("chess-pieces-dataset/models/detection_model-ex-02--loss-25.59.h5") 
detector.setJsonPath("chess-pieces-dataset/json/detection_config.json")
detector.loadModel()


detections = detector.detectObjectsFromImage(input_image="test.jpg", output_image_path="test-detected.jpg")

for detection in detections:
    print(detection["name"], " : ", detection["percentage_probability"], " : ", detection["box_points"])

Error:

File "[...]/venv/lib/python3.7/site-packages/imageai/Detection/Custom/__init__.py", line 1369, in draw_boxes_and_caption
    image_frame = cv2.rectangle(image_frame, (x1, y1), (x2, y2), class_color, 2)

Hi, did you end up solving this problem? I have the same issue currently

No, I don't. I drop the program since I couldn't manage to work.

It helped me to do the following in another application where I also use cv2.rectangle, to cast the variables image_frame = cv2.rectangle(image_frame, (int(x1), int(y1)), (int(x2), int(y2)), class_color, 2)

i am facing the same issue when using iamgeai :

Did you solve this issue?

嗨，你最终解决了这个问题吗？我目前有同样的问题

不，我没有。我放弃了该程序，因为我无法工作。

你解决了这个问题吗？
