can't use checkpoint/cascade_9.dat as classifier to predict~

[hu5tao]

hello ,I train a new model,and it will have 9 cascade model, from cascade_1 to cascade_9,when I compile successfully to detect:
./build/detect test_data_path/test.jpg checkpoints/cascade_1.dat
it will have a error:'the core has been dumped';
so if you have the checkpoint classfiler,can you send me a model,my email is:1010004295@qq.com,thanks
