### Installation
-Install TensorFlow. The code is tested under TF1.9 GPU version and Python 3.5 on Ubuntu 16.04. There are also some dependencies for a few Python libraries for data processing and visualizations like `cv2`. It's highly recommended that you have access to GPUs.
+Install TensorFlow. The code is tested under TF1.9.0 GPU version, g++ 5.4.0, CUDA 9.0 and Python 3.5 on Ubuntu 16.04. There are also some dependencies for a few Python libraries for data processing and visualizations like `cv2`. It's highly recommended that you have access to GPUs.
#### Compile Customized TF Operators
-The TF operators are included under `tf_ops`, you need to compile them first by `make` under each ops subfolder (check `Makefile`). Update `arch` in the Makefiles for different CUDA Compute Capability that suits your GPU if necessary. The code is tested under TF1.9.0.
