加载 ncnn 模型失败 #5

popper0912 · 2018-12-17T05:48:38Z

使用 Darknet 训练模型后，转化为 ncnn 模型，最后使用 ncnn 加载 .param 文件，返回 -1 ，加载失败。不知道何原因？使用caffe 训练的模型，转化后，可以加载成功。

应该是转换参数有问题，找到出现错误的操作，检查一下转换后的参数吧，如果方便可以提供下网络模型文件

我使用的是 yolov3-tiny 版的模型训练的自己的数据，darkNet cfg 文件如下：

我尝试注释掉 DarknetActivation 这一层加载便成功了不知道如何解决，请教一下

DarknetActivation 是自定义的网络层，你需要将其注册到ncnn network中，具体的你可以参考example/yolo.cpp

  CustomizedNet yolo;
  register_darknet_layer(yolo);
  yolo.load_param(param);

你好，我使用darknet2ncnn转换yolov2后运行模型文件时，提示“DarknetActivation”层是未知的层，对应的是darknet中activation=linear，这个激活层是您在项目中自己添加的吗？ #7
