Solution to " undefined symbol: _ZN10tensorflow8 .... "

[Wxjwjj]

Enev:
cuda: 9.0
cudnn: 9.0
tensorflow: 1.8.0
Ubuntu16.04

Makefile modified

 CUDA_HOME := /home/ <user name>/wuxj/cuda-9.0
 CGPUFLAGS: add your tensorflow library
 eg: -L /home/<user name>/.local/lib/python2.7/site-packages/tensorflow -ltensorflow_framework

Headers modified (from error)
vi cuda_device_functions.h / cuda_launch_config.h / cuda_kernel_helper.h
and modify the the headers
eg：

  #include "cuda/include/cuda_fp16.h"     to     #include "cuda_fp16.h"

I'm working with the same environment and made these edits.

I got the following:

File "/home/charles/Libraries/anaconda2/envs/tensorflow1.2/lib/python2.7/site-packages/tensorflow/python/framework/load_library.py", line 64, in load_op_library
None, None, error_msg, error_code)
tensorflow.python.framework.errors_impl.NotFoundError: src/ops/build/correlation.so: undefined symbol: _ZN10tensorflow16CorrelationGradAERKN5Eigen9GpuDeviceEiiiiiiiiiiiiiiiiiPKfS5_Pf

This is after commenting out -DGOOGLE_CUDA=1. With that, I get the following error during the make process:

48 errors detected in the compilation of "/tmp/tmpxft_000076b3_00000000-7_data_augmentation.cu.cpp1.ii".
