我想从头开始构建我自己的 Faster-RCNN 模型，用于从图像数据中进行多目标检测。

有人可以向我推荐一些好的资源来逐步实现更快的 RCNN 吗？

就准确性和执行时间而言，哪一个是好的 YOLO 或更快的 RCNN？

我一直在研究用于对象检测的 keras yolov3 模型。这个错误一直出现。这是错误：

AttributeError: module 'tensorflow.python.keras.backend' has no attribute 'get_graph'

我不知道该怎么办。我尝试将“import keras.module.module”替换为“tensorflow.keras.module.module”。但它仍然不起作用。

完整的输出代码：

runfile('G:/Traffic Violation Detection/object_detection.py', wdir='G:/Traffic Violation Detection')
Using TensorFlow backend.
Traceback (most recent call last):

当我flutter_linkify/flutter_linkify.dart在我的 flutter 项目中导入包时，我的控制台出现了这个错误：
