make pycaffe 报错

src/caffe/layers/box_annotator_ohem_layer.cu(49): error: a template argument may not reference a local type

Makefile:595: recipe for target '.build_release/cuda/src/caffe/layers/box_annotator_ohem_layer.o' failed

make: *** [.build_release/cuda/src/caffe/layers/box_annotator_ohem_layer.o] Error 1

解决方法：

box_annotator_ohem_layer uses C++11 features, you need to make changes to the makefile 

修改makefile

319行部分改成：

ifeq ($(DEBUG), 1)
    
    COMMON_FLAGS += -DDEBUG -g -O0 -std=c++11
    NVCCFLAGS += -G
else
    
    COMMON_FLAGS += -DNDEBUG -O2 -std=c++11
endif

训练的时候遇到的问题：AttributeError: 'module' object has no attribute 'text_format'

之前遇到过，没记录，现在记录下来。解决方法：

在出错的文件里加上：import google.protobuf.text_format

我这里错误提示在train.py里，所以找到train.py加上import google.protobuf.text_format
