Deep Learning Installation Tutorial - Index

Dear fellow deep learner, here is a tutorial to quickly install some of the major Deep Learning libraries and set up a complete development environment.


Deep Learning Installation Tutorial - Part 2 - Caffe, Tensorflow and Keras

There are a few major libraries available for Deep Learning development and research – Caffe, Keras, TensorFlow, Theano, and Torch, MxNet, etc. These libraries use GPU computation power to speed up deep neural networks training which can be very long on CPU (+/- 40 days for a standard convolutional neural network for the ImageNet Dataset).

NVIDIA is definetely the brand to go for Deep Learning applications, and for now, the only brand broadly supported by deep learning libraries.

In these Tutorials, we will explore how to install and set up an environment to run Deep Learning tasks.

A few useful links :


In this post, we will install the following libraries:

  • Caffe: "Caffe is a deep learning framework made with expression, speed, and modularity in mind." (Source)
  • Tensorflow: "TensorFlow is an open source software library for numerical computation using data flow graphs." (Source)
  • Theano: "Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently with a tight integration with NumPy" (Source)

A. Installing Caffe

Caffe is one of the main deep learning libraries for visual data analysis, and it was the first library I learned to train deep neural networks. Fast and reliable, working on android, I really appreciate using this library.

In July 2017, Caffe is compiled to use Cuda Toolkit 8.0, cuDNN 5.1 and OpenCV 2 or 3.

First, we need to make sure the system is up to date:

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y

Then, we want to install the dependencies:

sudo apt-get install -y gcc g++ gfortran cmake build-essential linux-image-generic
sudo apt-get install -y git wget pkg-config

sudo apt-get install -y   
sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libhdf5-serial-dev protobuf-compiler llibopencv-dev
sudo apt-get install -y --no-install-recommends libboost-all-dev
sudo apt-get install -y libgflags-dev libgoogle-glog-dev liblmdb-dev libblas-dev libatlas-base-dev libopenblas-dev

# (Python 2.7 development files)
sudo apt-get install -y python-dev
sudo apt-get install -y python-pip
sudo apt-get install -y python-nose python-numpy python-scipy

# (or, Python 3.5 development files)
sudo apt-get install -y python3-dev
sudo apt-get install -y python3-pip
sudo apt-get install -y python3-nose python3-numpy python3-scipy
# Python2
sudo pip install numpy scipy scikit-learn protobuf

# Python3
sudo pip3 install numpy scipy scikit-learn protobuf

Then we need the Python Package CUDAMat:

git clone https://github.com/cudamat/cudamat
cd cudamat

# Python2
python setup.py build
sudo python setup.py install

# Python3
python3 setup.py build
sudo python3 setup.py install

For AWS Users: You will need to disable the camera driver or the computer will complain while working with images:

sudo ln /dev/null /dev/raw1394

Now, we are ready to install Caffe:

cd ..
git clone https://github.com/BVLC/caffe.git
cd caffe
cp Makefile.config.example Makefile.config
make all
make test
make runtest
make pycaffe

Let us check that the installation is correct:

make pycaffe

Now, we need to compile the pycaffe library:

echo -e "\nexport PYTHONPATH=/path/to/caffe/python:$PYTHONPATH" >> .bashrc

You can now test your caffe installation:

python
>>> import caffe

B. Installing TensorFlow

TensorFlow is one of the most supported library for deep learning applications and research. A low-level library which is extremely flexible when you need to access low-level features and precisely your models.

It is also one of the easiest library to install:

CPU-Only Installation:

# Python2
sudo pip install tensorflow

# Python3
sudo pip3 install tensorflow

GPU-Enabled Installation:

# Python2
sudo pip install tensorflow-gpu

# Python3
sudo pip3 install tensorflow-gpu

Let us try the installation:

python
>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> sess.run(hello)
'Hello, TensorFlow!'
>>> a = tf.constant(10)
>>> b = tf.constant(32)
>>> sess.run(a + b)
42

C. Installing Theano

Theano is great library that allows you to manage your data in a very similar way that NumPy does, which is very pratical for long time python users.

This library is also quite easy to install:

# Python2
sudo pip install Theano

# Python3
sudo pip3 install Theano

Let us try the installation:

python
>>> from theano import tensor as T, function, printing
>>> x = T.dvector()
>>> hello_world_op = printing.Print('hello world')
>>> printed_x = hello_world_op(x)
>>> f = function([x], printed_x)
>>> r = f([1, 2, 3])
hello world __str__ = [ 1.  2.  3.]

D. Conclusion

We have now installed Caffe, TensorFlow and Theano. You can try to explore many of the available ressources online or keep installing the other libraries.
