Installing NVIDIA Driver & CUDA inside an LXC container running Ubuntu 16.04 on a neuroscience computing server.

Introduction: I was trying to run some neuroscience image processing commands that uses NVIDIA GPU. The challenge is that most of our computation will be run inside an LXC container running Ubuntu 16.04 (the host runs Ubuntu 16.04 as well). Installing the NVIDIA driver on the host is not so hard, but doing it inside the LXC container is much more challenging.

I already have an unprivileged container running, so I will not repeat the steps to create an LXC container here.

Our graphics card is NVIDIA GeForce GTX 1080 Ti.

Here are the main steps:

import sqlite3
import json

conn = sqlite3.connect('test.db')
c = conn.cursor()

# Insert values
c.execute('''insert into data values(?)''', (json.dumps({'test':'test2'}),))
conn.commit()
