Ubuntu: installing TensorFlow for NVidia (CUDA) GPU

I am setting TensorFlow on:

• Ubuntu 16.04 LTS 64-bit
• 16 GiB RAM
• AMD Athlon(tm) II X4 640 Processor × 4 
• GeForce GTX 1050 Ti/PCIe/SSE2

Check if you have NVidia CUDA GPU

uki@uki-p6710f:~$  lspci | grep -i nvidia
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1c82 (rev a1)
