Question

我正在运行代码以从本文中学习如何教AI / ML用于对象检测： https://medium.com/deepquestai/train-object-detection-ai-with-6-lines-of-code-6d087063f6ff （非常棒的BTW;-）

我下载了预训练的模型并在Google Colab上运行

似乎我收到了以下错误： ''' --> 761 image_frame = image.copy() 762 image_frame2 = image.copy() 763 height, width, channels = image.shape

'AttributeError: 'NoneType' object has no attribute 'copy' 
on line 8: ----> 8 detections = 
detector.detectObjectsFromImage(input_image="holo3.jpg", 
output_image_path="holo3-detected.jpg")'

请问有什么可以帮助的，因为它应该是经过预先训练，经过测试的代码？

我搜索了Stackoverflow，但没有找到答案。

from imageai.Detection.Custom import CustomObjectDetection

detector = CustomObjectDetection()
detector.setModelTypeAsYOLOv3()
detector.setModelPath("hololens-ex-60--loss-2.76.h5") 
detector.setJsonPath("detection_config.json")
detector.loadModel()
detections = detector.detectObjectsFromImage(input_image="holo3.jpg", 
output_image_path="holo3-detected.jpg")
for detection in detections:
print(detection["name"], " : ", detection["percentage_probability"], " : ", detection["box_points"])

AttributeError                            Traceback (most recent call last)

由于图像文件夹中不存在火车和验证文件夹注释XML图像路径，我发现了类似的错误。检查图像名称与注释XML文件路径相同。
