oc工程搭建

[brightzhengh]

ncnn应该要初始化文件，看android里工程里有assets里有相关文件；
oc的话应该是参考在linux的示例吧？
net.load_param("model.param");
net.load_model("model.bin");
这两个文件怎么生成？

param 文件的路径不对

[brightzhengh]

@nihui 这个要传相对路径还是全路径，image我也是这样读的能读到

[nihui]

pathforresource 后面 oftype param ...

[brightzhengh]

用的example的资源文件，squeezenet_v1.1.param.bin 是param文件吧？

[nihui]

#24

[brightzhengh]

不是一个param是squeezenet_v1.1.param.bin，一个model文件是squeezenet_v1.1.bin；难道要改名？

[brightzhengh]

我用NSFileHandle方式能读到文件，且文件大小一样；在这个地方挂的原因是？
frame #4: 0x00000001035d7a98 ncnndemo`ncnn::Net::load_param(__sFILE*) + 1560

[nihui]

squeezenet_v1.1.param.bin 是用 load_param_bin 加载的

[brightzhengh]

OK，确实这个问题导致，谢谢！
