why?

what is your gcc version and python version?

[zhangtao22]

中间有两个编译依赖错误，我都解决了，最后编译出来了，报了一个这个错误
tensorflow.python.framework.errors_impl.NotFoundError: /home/zhangtao/work/InceptText-Tensorflow/lib/deform_conv_layer/deform_conv.so: undefined symbol: _ZN10tensorflow8internal21CheckOpMessageBuilder9NewStringB5cxx11Ev

[FakerYFX]

just follow this one CharlesShang/TFFRCNN#108

[zhangtao22]

我这边是gcc5，是把下边注释打开，把上边注释掉是吧，Python是2.7

if you install tf using already-built binary, or gcc version 4.x, uncomment the two lines be low

g++ -std=c++11 -shared -o roi_pooling.so roi_pooling_op.cc
roi_pooling_op.cu.o -I $TF_INC -I $NSYNC_INC -fPIC -D GOOGLE_CUDA -lcudart -L $CUDA_HOM E/lib64 -L $TF_LIB -ltensorflow_framework -D_GLIBCXX_USE_CXX11_ABI=0

for gcc5-built tf

g++ -std=c++11 -shared -o roi_pooling.so roi_pooling_op.cc \

roi_pooling_op.cu.o -I $TF_INC -I $NSYNC_INC -fPIC -D GOOGLE_CUDA -lcudart -L $CUDA_HOM E/lib64 -L $TF_LIB -ltensorflow_framework -D_GLIBCXX_USE_CXX11_ABI=0

[FakerYFX]

yes,have a try

[zhangtao22]

试了，把所有gcc5打开，上边的注释掉，还是这个错误tensorflow.python.framework.errors_impl.NotFoundError: /home/zhangtao/work/InceptText-Tensorflow/lib/deform_conv_layer/deform_conv.so: undefined symbol: _ZN10tensorflow8internal21CheckOpMessageBuilder9NewStringB5cxx11Ev

感觉除了降gcc g++版本没有其他办法了

@zhangtao22 请问除了去gcc5相关掉注释，还用改其他值吗？我报错跟你不一样。

4 errors detected in the compilation of "/tmp/tmpxft_00005a43_000000007_deform_psroi_pooling_op_gpu.cu.cpp1.ii".

[zhangtao22]

你这个问题我没有遇到过啊

好吧，谢谢。

[FakerYFX]

have you solved your problem when change the gcc version @zhangtao22

[zhangtao22]

@xieyufei1993 没有

[FakerYFX]

the error is what?

[zhangtao22]

还是解决不了啊
