【问题描述】:
我在 jupyter notebook 上做一个手语检测项目。在运行实时检测代码时,我遇到了如下所示的错误:
OpenCV(4.5.1) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-1drr4hl0\opencv\modules\highgui\src\window.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
尽管尝试了许多我在网上找到的解决方案,但我仍然遇到同样的错误。
遇到错误的代码是: 而真: 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!

-
你是如何安装 OpenCV 的?你自己建的吗?
-
使用 pip 安装
