MATLAB is exiting because of fatal error
Killed
Makefile:540: recipe for target 'mattest' failed
make: *** [mattest] Error 137
when I run the 26th lines of code in the "run_cascadercnn_coco.m",this error is made.
当用matlab运行测试模型时，一进入到第26行的代码net = caffe.Net(definition_file, binary_file, 'test')就会报上述错误，在make mattest时也会报这个错误。
