问题描述

---

python -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"

出现这个问题

ERROR: something wrong with flag 'flagfile' in file '/home/bids/softwares/gflags-2.2.0/src/gflags.cc'.  One possibility: file '/home/bids/softwares/gflags-2.2.0/src/gflags.cc' is being linked both statically and dynamically into this executable.

这是因为之前设置　Ubuntu 15.04 安装 boost-python , 导致 gflags.cc 指向了　

/usr/local/lib/libgflags.a 　/usr/local/lib/libgflags_nothreads.a　和　 /usr/local/include/gflags

caffe2调用gflags会出现矛盾。
