Error in compiling cuda code

[shahdev]

I compiled the makefile succesfully

When I run python train_nn.py I get this error:
tensorflow.python.framework.errors_impl.NotFoundError: ./tf_nndistance_so.so: undefined symbol: _ZN10tensorflow12OpDefBuilder5InputESs

I am using a conda environment with python2.7, tensorflow 1.4 and gcc 4.8

This is my makefile:
nvcc = /usr/local/cuda-10.2/bin/nvcc
cudalib = /usr/local/cuda-10.2/lib64/
tensorflow = /home/dpshah2/.conda/envs/PSRNet/lib/python2.7/site-packages/tensorflow/include
tf_lib = /home/dpshah2/.conda/envs/PSRNet/lib/python2.7/site-packages/tensorflow

I have the same issue. It would be great if someone who were able to successfully compile the cuda code post their environment details.

I am using: tensorflow 1.4.0, cuda: 8.0 and cudnn: 6

[justanhduc]

@shahdev @sbharadwajj I have successfully compiled with tf1.1 (downloaded with pip), cuda 8.0 and python 2.7.

@justanhduc can you share the makefile and how you managed to get it to work?

[justanhduc]

@shahdev I didn't do anything special besides fixing the CUDA path in the makefile. But I notice that I had to use a fresh clone to make it work, as I tried to compile with Python 3 but it failed, then I removed all the .so files and compiled again with Python 2 but it didn't work.
The make file is below

nvcc = ${CUDA_HOME}/bin/nvcc
cudalib = ${CUDA_HOME}/lib64/
tensorflow = ${HOME}/miniconda3/envs/py27/lib/python2.7/site-packages/tensorflow/include

Sorry for bothering you.
Could you explain what address the ${CUDA_HOME} stands for?
I am using anaconda, it seems the CUDA was not installed in /usr/local/cuda-x.x/bin/nvcc
But I am not sure where it is.
Thanks in advance

Hi @dwindy. You can check where your nvcc is using which nvcc in terminal. Then set ${CUDA_HOME} to be until the bin folder. Good luck!

Hi @justanhduc . Yes, I found it. Thank you!
