问题描述
我有tiny yolo v3
个预先训练的模型,我想在C#中使用它,以便能够检测对象。
我遇到了以下working sample code,但该教程是针对具有以下属性的tiny yolo v2
模型制作的:
我的预训练模型具有以下属性:
因此,不仅名称,输出数量和输入/输出参数不兼容。由于ML不是我的专长,因此我在迁移代码以支持我拥有的这种新模型方面遇到困难。
到目前为止,我所做的是:
- 将所有出现的输入参数
image
重命名为值000_net
- 将所有出现的输出参数
grid
重命名为值016_convolutional
- 更改值(this section)

public const int ROW_COUNT = 13;
public const int COL_COUNT = 13;
public const int CHANNEL_COUNT = 125;
public const int BoxES_PER_CELL = 5;
public const int Box_INFO_FEATURE_COUNT = 5;
public const int CLASS_COUNT = 20;
public const float CELL_WIDTH = 32;
public const float CELL_HEIGHT = 32;
进入(根据提供模型的人的评论):
public const int ROW_COUNT = 13;
public const int COL_COUNT = 13;
public const int CHANNEL_COUNT = 18;
public const int BoxES_PER_CELL = 3;
public const int Box_INFO_FEATURE_COUNT = 5;
public const int CLASS_COUNT = 1;
public const float CELL_WIDTH = 32;
public const float CELL_HEIGHT = 32;
我还用训练模型的一个类替换了类名。
在所有更改之后的最终结果中,该应用程序未引发错误,但显示警告,并且未按预期检测到对象。这是我得到的输出:
警告说:
