错误:(-2:未指定的错误)该功能未实现.使用 Windows、GTK+ 2.x 或 Cocoa 支持重建库 [英] error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support

问题描述

我在 jupyter notebook 上做一个手语检测项目.运行实时检测代码时遇到如下错误:

I was working on a sign language detection project on jupyter notebook. While running the code for live detection I encountered an error as shown below:

OpenCV(4.5.1) C:UsersappveyorAppDataLocalTemp1pip-req-build-1drr4hl0opencvmoduleshighguisrcwindow.cpp:651:错误:(-2:Unspecified error) 功能未实现.使用 Windows、GTK+ 2.x 或 Cocoa 支持重建库.如果您在 Ubuntu 或 Debian 上，请安装 libgtk2.0-dev 和 pkg-config，然后重新运行 cmake 或在函数 'cvShowImage' 中配置脚本

OpenCV(4.5.1) C:UsersappveyorAppDataLocalTemp1pip-req-build-1drr4hl0opencvmoduleshighguisrcwindow.cpp:651: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

尽管尝试了很多我在网上找到的解决方案，但我仍然遇到同样的错误.

Despite of trying many solutions that I found online I'm still getting the same error.

遇到错误的代码是:而真:ret, frame = cap.read()image_np = np.array(frame)

The code that encountered error is : while True: ret, frame = cap.read() image_np = np.array(frame)

input_tensor = tf.convert_to_tensor(np.expand_dims(image_np, 0), dtype=tf.float32)
detections = detect_fn(input_tensor)

num_detections = int(detections.pop('num_detections'))
detections = {key: value[0, :num_detections].numpy()
              for key, value in detections.items()}
detections['num_detections'] = num_detections

# detection_classes should be ints.
detections['detection_classes'] = detections['detection_classes'].astype(np.int64)

label_id_offset = 1
image_np_with_detections = image_np.copy()

viz_utils.visualize_boxes_and_labels_on_image_array(
            image_np_with_detections,
            detections['detection_boxes'],
            detections['detection_classes']+label_id_offset,
            detections['detection_scores'],
            category_index,
            use_normalized_coordinates=True,
            max_boxes_to_draw=5,
            min_score_thresh=.5,
            agnostic_mode=False)

cv2.imshow('object detection',  cv2.resize(image_np_with_detections, (800, 600)))

if cv2.waitKey(1) & 0xFF == ord('q'):
    cap.release()
    break

请帮帮我！

推荐答案

我在 windows 10 上使用 yolov5 时遇到了完全相同的错误.通过键入重新构建库

I had the exact same error using yolov5, on windows 10. Rebuilding the library by typing

pip uninstall opencv-python 

然后

pip install opencv-python

为我工作.
