Instalasi Cuda di Ubuntu 16.04: Part 1

Kalau kalian sedang ingin belajar Deep Learning dan ingin mencoba utak-atik tensorflow, maka kalian pasti sadar kalau tensorflow tidak mau berjalan di Windows. Karenanya kali ini, mau sedikit lagi berbagi pengalaman langkah yang saya pakai untuk instalasi NVIDIA Cuda di Ubuntu.

Kalau mau langsung cepat, silakan baca bagian Referensi

Proses dan pengalaman

1. Awalnya saya ngiranya driver NVIDIA akan otomatis terinstall di Ubuntu 16.04 *kayaknya dikabarin sama siapa gitu, dan percaya-percaya saja* Karena kepercayaan itu langkah pertama yang saya lakukan adalah langsung download Cuda.

2. Setelah terdownload (cuda_7.5.18_linux.run) langsung run dengan perintah:

sudo sh cuda_7.5.18_linux.run --override

3. Nah, karena pas lagi install saya masih PeDe sudah ada nvidia drivernya akhirnya ketika ditawarin di menu installnya untuk instal nvidia driver saya ya jawab NO dan setelah itu proses instalasi tetap berjalan lancar dan berhasil.

4. Setelah berhasil terinstal, saya pingin coba cek apakah Cuda sudah berjalan dengan memainkan file sampel Cuda nya. Caranya tinggal tuju folder `home/user/NVIDIA_CUDA-7.5_Samples/1_Utilities/deviceQuery` Setelah itu, open terminal di lokasi tersebut dan run perintah `make` di terminal. Lalu jalankan program device query dengan perintah `./deviceQuery`.

5. Dan munculah tulisan seperti ini 🙁

-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

6. Error tersebut menyadarkan ada yang salah dengan NVIDIA drivernya. Setelah coba cek dengan beberapa cara untuk mengecek apakah NVIDIA driver sudah terinstall, dengan perintah dpkg -l | grep nvidia, ternyata driver NVIDIA nya memang belum terinstall dengan baik 😐 karenanya saya langsung memulai proses instalasi NVIDIA Drivernya

How Do I Learn Neural Network (and Deep Learning)

First, I am nobody in this topic, please don’t hesitate to give better suggestion. This is actually just a “documentation” about my experience when I work on my undergraduate thesis in 2015. Once again, please don’t hesitate to discuss and give better suggestion about this topic, or.. correct my English if I made some mistakes 🙂

Background

Okay, before I tell you my story, I’ll tell you about my background when I started to learn neural network. I wrote this section only have one intention, to make you easy measure what you need, nothing else.

  1. I have familiarity with some of mathematical symbols, like how to read sigma symbol, derivative symbol and many others (but not every symbols).
  2. I have familiarity with basic math operation like derivative function, algebra, matrix and vector operation (but only “the basic”).
  3. I’ve never coded in python, but I’ve been using C++ around 2-3 years and I used to code  Matlab style programming language in some project before (and thanks, this knowledge is very helpful)
  4. I studied the Introduction of Artificial Intelligence at the fourth semester in college, but I won’t said I did it well 🙁

After a month googling randomly, I started to make a list what should I learn, the order of the list below it’s just the best order in my opinion. In my experience I jumped many times over the topic because at that time, I didn’t know what I didn’t know 🙁

If you want to learn about Deep Learning, lets begin with: What is Machine Learning?

Then start to learn about Neural Network

Let’s do some math, Backpropagation?

I suggest you to fully-understand this algorithm in order to give some intuitions to help you in model tuning or error handling when you start implement the neural network

  • Easy start : I watched again the neural network demistifyed, and slowly got the intuition how backpropagation work, I followed and tried the math step-by-step
  • Watch the 4th week on Coursera Introduction to Machine Learning
  • Try the example of how backpropagation works : https://mattmazur.com/2015/03/17/a-step-by-step-backpropagation-example/
  • Read carefully the second chapter from http://neuralnetworksanddeeplearning.com/
  • And if you start thinking they have different formula / calculation / interpretation, start to prove that you are wrong. I started to compare all the calculations to understand more

Python for machine learning?

So what is Deep Learning?

What is Convolutional Neural Network (I use CNN in my undergraduate thesis)?

Backpropagation in CNN?

I don’t know it is necessary or not, but I learned it. I think if you understand the basic of backpropagation it’s enough. But if you are curious how backpropgation through max pooling or convolution layer, it does not hurt to learn it.

And…great, It’s done, That’s all my references that I used when I did my undergraduate thesis, I hope it will be useful for someone :/ or at least for me in the future 🙂
