Issue summary

Hello, thanks for your attention. I build the caffe environmnet follow the tutorial, and make runtest without error. I try to train the example module by python examples/ssd/ssd_Pascal.py. when the script arrives to conv1_1 ->con1-1 , it alway present the problem that "*Aborted at ** (unit time) try "data -d @" if you are using GNU date***" Here is my job I0522 12:55:37.963074 23676 layer_factory.hpp:77] Creating layer conv1_1 I0522 12:55:37.963090 23676 net.cpp:100] Creating Layer conv1_1 I0522 12:55:37.963095 23676 net.cpp:434] conv1_1 <- data_data_0_split_0 I0522 12:55:37.963104 23676 net.cpp:408] conv1_1 -> conv1_1 Aborted at 1526964938 (unix time) try "date -d @1526964938" if you are using GNU date PC: @ 0x7fb4611445bb (unknown) SIGSEGV (@0x4) received by PID 23676 (TID 0x7fb46086c700) from PID 4; stack trace: *** @ 0x7fb491be04b0 (unknown) @ 0x7fb4611445bb (unknown) @ 0x7fb4617123fd (unknown) @ 0x7fb461147426 (unknown) @ 0x7fb461125170 (unknown) @ 0x7fb461723f9d (unknown) @ 0x7fb46112bfd2 (unknown) @ 0x7fb46112e391 (unknown) @ 0x7fb461124aec __cuda_CallJitEntryPoint @ 0x7fb4694245c2 fatBinaryCtl_Compile @ 0x7fb3d357cf92 (unknown) @ 0x7fb3d357db13 (unknown) @ 0x7fb3d357e1e3 (unknown) @ 0x7fb3d3478277 (unknown) @ 0x7fb3d3478b1d (unknown) @ 0x7fb3d3477a9d (unknown) @ 0x7fb4895dcac9 (anonymous namespace)::opencl_fn6<>::switch_fn() @ 0x7fb489773c49 cv::ocl::Context::getDefault() @ 0x7fb48977548b cv::ocl::Device::getDefault() @ 0x7fb4897754ed cv::ocl::useOpenCL() @ 0x7fb487b9480c cv::resize() @ 0x7fb493cbfe8a caffe::ApplyResize() @ 0x7fb493d227c2 caffe::DataTransformer<>::Transform() @ 0x7fb493d25ac1 caffe::DataTransformer<>::Transform() @ 0x7fb493d2eabb caffe::DataTransformer<>::Transform() @ 0x7fb493d2ebb8 caffe::DataTransformer<>::Transform() @ 0x7fb493d2ec8e caffe::DataTransformer<>::Transform() @ 0x7fb493c2f679 caffe::AnnotatedDataLayer<>::load_batch() @ 0x7fb493bbcfdf caffe::BasePrefetchingDataLayer<>::InternalThreadEntry() @ 0x7fb493d32595 caffe::InternalThread::entry() @ 0x7fb486e2b5d5 (unknown) @ 0x7fb47f2f06ba start_thread

i guess that it is possible for my bad caffe-environment. So i try to run mnist and cifar train, and the result is success. i guess that the dataset maybe become mistake. So i make my datatset from VOC2007 follow the tutorial, and the result also be error in the same place.

Then i find many way from the internet

sudo python examples/ssd/ssd_pascal.py it present NO module name caffe. but, i can import caffe without sudo.

2.someone say recompile the opencv without opencl i try to do that, but also not use. i put CMakefile --WITH_OPENCL = OFF; and WITH_OPENCLAMDFFT,WITH_OPENCLAMDBLAS,WITH_VA_INTEL also being OFF ( i cmake opencv and can see the opencl is NO )

Finally, i do not know how to solve the problem. Forgive my lame English, and hoping to get a suggestion.

Steps to reproduce

If you are having difficulty building Caffe or training a model, please ask the caffe-users mailing list. If you are reporting a build error that seems to be due to a bug in Caffe, please attach your build configuration (either Makefile.config or CMakeCache.txt) and the output of the make (or cmake) command.

Your system configuration

Operating system:ubuntu 16.04.3 Compiler: OpenCV:3.1.0 CUDA version (if applicable): 8.0 CUDNN version (if applicable):5.1.10 BLAS: Python or MATLAB version (for pycaffe and matcaffe respectively): Python

你好，请问你解决这个问题了吗？我也遇到了相同的问题

重装了caffe，就可以了。我猜应该是环境被破坏了。
