yolov3.cfg我正在尝试通过yolov3.weights使用darkflow. 但是，当我尝试运行时tfnet = TFNet(history)，它会引发“未定义退出”的错误。

我已darkflow按以下步骤安装：

在 Anaconda 提示中：

git clone https://github.com/thtrieu/darkflow.git
cd darkflow
python3 setup.py build_ext –inplace
pip install

然后：

%matplotlib inline

import matplotlib.pyplot as plt

import numpy as np


import cv2

from darkflow.net.build import TFNet

history = {"model": "C:/Users/Business Intelli/Desktop/Object-Detection/Dataset/yolov3.cfg",

           "load": "C:/Users/Business Intelli/Desktop/Object-Detection/Dataset/yolov3.weights",

           "batch": 8,

           "epoch": 50,

           "gpu": 1.0,

           "train": True,

           "annotation": "C:/Users/Business Intelli/Desktop/Object-Detection/Dataser/Stumps",

           "dataset": "C:/Users/Business Intelli/Desktop/Object-Detection/Dataser/Stumps"}


tfnet = TFNet(history)

所以我遇到了同样的问题，问题出在 darkflow --> utils 文件夹中的 process.py 文件上。

显然 exit() 方法不是内置的，所以你必须在process.py中添加这一行

从系统导入退出

注意：如果您的代码达到这一点，则意味着模型无法读取图层。我为 yolov3 下载的权重文件给了我同样的麻烦，我找不到在暗流中工作的 yolov3 具有适当权重文件的链接。所以我不得不坚持使用 yolo.cfg 和 yolo.weights 。
