python - 将yolov4权重转换为tflite时如何解决reshape ValueError？

问题描述

当我尝试将 yolov4 权重转换为 tflite 时，发生了 ValueError。我无法解决这个问题并找到合适的答案。这个权重文件在 PycharmProject .py 文件中可用，我可以在对象检测代码中找到它。但是在转换为tflite的过程中，出现了ValueError。



使用的 GitHub 链接： tensorflow_yolov4_tflite tensorflow-yolov4

我引用了这个 StackOverflow Q&A，但它不起作用。 无法将 YOLOv4 转换为 tflite



这是错误代码。

（convert_tflite.py 和 convert.py (to pb) 也不起作用。）

检查一下，它将解决问题。

基本上，您正在克隆根存储库以运行此文件，同时保持 core/config.py 中的路径不变。
