在安装好的 caffe 环境里训练模型时报错
$ cd <caffe根目录>
$ ./build/tools/caffe train -solver examples/mnist/lenet_solver.prototxt
...

Aborted (core dumped)问题原因是没有找到训练用的数据，所以我们需要先下载训练数据，如下
$ cd <caffe根目录>
$ ./data/mnist/get_mnist.sh
$ ./examples/mnist/create_mnist.sh然后重新运行训练模型
$ cd <caffe根目录>
$ ./build/tools/caffe train -solver examples/mnist/lenet_solver.prototxt
或
$ ./examples/mnist/train_lenet.sh本文参与 腾讯云自媒体分享计划，分享自作者个人站点/博客。
