tf_ops compilation and CUDA version

[Vishak66]

Hello Lin,

Do I need to compile the .sh scripts under tf_ops first? Kindly advise on how to compile the tf operators.

Also did you test it in a specific cuda/cudnn version?

@Vishak66 The code is tested under TF1.7 GPU version, CUDA 9.0, cudnn 7.0.5 and Python 3.6 on Ubuntu 16.04. There are also some dependencies for a few Python libraries for data processing like h5py etc. It's highly recommended that you have access to GPUs. The TF operators are included under tf_ops, you need to compile them (check tf_xxx_compile.sh under each ops subfolder) first. Update nvcc and python path if necessary. Then, you can compile it by sh tf_xxx_compile.sh.

Hello Lin,

I am trying to compile the tf_xxx_compile.sh. I am working with TF1.4 and Python 3.5, following the JSNet instructions (I am working with the udocker image tensorflow/tensorflow:1.4.0-gpu-py3). When I execute the one in the folder 3d_interpolation I have the following error:

tf_interpolate.cpp:6:37: fatal error: tensorflow/framework/op.h: No such file or directory
compilation terminated.

I have not modified anything beause I have seen that the pointnet++ original file has been modified in JSNet to work with TF1.4.

To see what could be, I have downloaded pointnet++ code. I have try to compile the same file using TF1.2 and Python 3.5 (udocker image tensorflow/tensorflow:1.2.0-gpu-py3). I have got the same error.

Last, I have tried to compile that file (the one in pointnet++, not in JSNet) using TF1.2 and Python 2.7 (udocker image tensorflow/tensorflow:1.2.0-gpu) and it works. Maybe the problem is the python version. However, it is not suitable for working with JSNet, since it uses Python 3.5 and TF1.4.

What am I doing wrong? Do I have to modified any file in the JSNet repository?

@Daniel22L Maybe you should update the path of Tensorflow in each tf_xxx_compile.sh.
You can try to modify $HOME/anaconda3/envs/tensorflow_1.4/lib/python3.5/site-packages/tensorflow to /usr/local/lib/python3.5/dist-packages/tensorflow or other correct path.
