Pyzed.sl has no attribute DETECTION_MODEL

After installing ZED SDK 4, I get this error in custom_detector.py line 166

pyzed.sl has no attribute DETECTION_MODEL

And I checked pyzed.sl has DEPTH_MODE and DevicePeroperties() but hasn’t the DETECTION_MODEL

Hi, that’s because DETECTION_MODEL does not exist anymore in 4.0. You sample is outdated.
It’s now OBJECT_DETECTION_MODEL or BODY_TRACKING_MODEL depending on what you do.

Thanks,

That makes sense. But seems like the custom detector sample in ‘samples/custom detector/python/python_yolov5/detector.py’ in ZED SDK 4 installation is not up-to-date.
Please make this update.
In the meantime, where do I get an updated version of this sample?

As you ca see here:

github.com

stereolabs/zed-sdk/blob/master/object detection/custom detector/python/pytorch_yolov5/detector.py

#!/usr/bin/env python3

import sys
import numpy as np

import argparse
import torch
import cv2
import pyzed.sl as sl
import torch.backends.cudnn as cudnn

sys.path.insert(0, './yolov5')
from models.experimental import attempt_load
from utils.general import check_img_size, non_max_suppression, scale_coords, xyxy2xywh
from utils.torch_utils import select_device
from utils.augmentations import letterbox

from threading import Lock, Thread
from time import sleep

This file has been truncated. show original

the detector.py is not up-to-date.

As seen here, It’s my bad luck that only the custom detector is not up-to-date. And it’s sounds to me that it’s a bad software development behaviour to suddenly change a bunch of APIs without having a support for legacy codes people are using.

Sorry for your troubles. We’ll update this sample very soon, probably next week.

In the meantime, legacy code are still working as before with 3.8.2. Our SDK 4.0 is in early access, but is very stable already and all these little issues like the one you found will be resolved in no time.

im having the same issue with SENSING_MODE and ZED SDK 4.
AttributeError: module ‘pyzed.sl’ has no attribute ‘SENSING_MODE’

Hello,

It’s the same thing. The sensing mode does not exist anymore in 4.0. it was replaced by a boolean RuntimeParameters Class Reference | API Reference | Stereolabs
