+### Installation instructions for Ubuntu 16.04
+     
+* Make sure <a href="https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html">CUDA</a>  and <a href="https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html">cuDNN</a> are installed. Three configurations have been tested: 
+     - TensorFlow 1.4.1, CUDA 8.0 and cuDNN 6.0
+     - TensorFlow 1.12.0, CUDA 9.0 and cuDNN 7.4
+     - ~~TensorFlow 1.13.0, CUDA 10.0 and cuDNN 7.5~~ (bug found only with this version).
+     
+* Ensure all python packages are installed :
+
+          sudo apt update
+          sudo apt install python3-dev python3-pip python3-tk
+
+* Follow <a href="https://www.tensorflow.org/install/pip">Tensorflow installation procedure</a>.
+
+* Install the other dependencies with pip:
+     - numpy
+     - scikit-learn
+     - psutil
+     - matplotlib (for visualization)
+     - mayavi (for visualization)
+     - PyQt5 (for visualization)
+     
+* Compile the customized Tensorflow operators located in `tf_custom_ops`. Open a terminal in this folder, and run:
+
+          sh compile_op.sh
+
+     N.B. If you installed Tensorflow in a virtual environment, it needs to be activated when running these scripts
+     
+* Compile the C++ extension module for python located in `cpp_wrappers`. Open a terminal in this folder, and run:
+
+          sh compile_wrappers.sh
+
+You should now be able to train Kernel-Point Convolution models

+### Installation instructions for Ubuntu 18.04 (Thank to @noahtren)
+
+* Remove the `-D_GLIBCXX_USE_CXX11_ABI=0` flag for each line in `tf_custom_ops/compile_op.sh` (problem with the version of gcc). One configuration has been tested:
+
+     - TensorFlow 1.12.0, CUDA 9.0 and cuDNN 7.3.1
