# Ubuntu 16.04: Upgrade to TensorFlow 1.4

## post by sabalaba on Dec 21, 2017

Tensorflow 1.4 now requires cuDNN 6. Follow these steps:

1. Download cuDNN 6 from NVIDIA here:
   [Log in | NVIDIA Developer](https://developer.nvidia.com/rdp/form/cudnn-download-survey)
2. Extract cuDNN to your CUDA directory:
   `sudo tar xvf <PATH_TO_CUDNN_6> -C /usr/local/cuda-8.0 --strip-components=1`
3. Install Tensorflow 1.4:
   `sudo pip install tensorflow-gpu==1.4.1`

Make sure that CUDA 8 is installed. You can verify this with `nvcc --version`. If not, you’ll need to install CUDA 8. Download the runfile and install it like this:
   `sudo sh <PATH_TO_CUDA_8_RUN> --silent --toolkit --no-opengl-libs`
