Intel® Computer Vision SDK: Getting Started with the Intel® Computer Vision SDK (Intel® CV SDK)

Using Caffe with the Intel *

Deep Learning Model Optimizer for Caffe* requires the Caffe framework to be installed on the client machine with all relevant dependencies. Caffe should be dynamically compiled and linked. A shared library named libcaffe.so should be available in the CAFFE_HOME/build/lib directory.

For ease of reference, the Caffe* installation folder is referred to as <CAFFE_HOME> and the Model Optimizer installation folder is referred to as <MO_DIR>.

The installation path to the Model Optimizer depends on whether you use the Intel® CV SDK or Deep Learning Deployment Toolkit. For example, if you are installing with sudo, the default <MO_DIR> directory is:

• /opt/intel/deeplearning_deploymenttoolkit_<version>/deployment_tools/model_optimizer - In case of using Deep Learning Deployment Toolkit
• /opt/intel/computer_vision_sdk_<version>/mo - In case of Intel CV SDK installation.

Installing Caffe

To install Caffe, complete the following steps:

1. For convenience, set the following environment variables:

     export MO_DIR=<PATH_TO_MO_INSTALL_DIR>
     export CAFFE_HOME=<PATH_TO_YOUR_CAFFE_DIR>

2. Go to the Model Optimizer folder:

   cd $MO_DIR/model_optimizer_caffe/

3. For easiness of the installation procedure, you can find two additional scripts in the $MO_DIR/model_optimizer_caffe/install_prerequisites folder:
   • install_Caffe_dependencies.sh - Installs the required dependencies like Git*, CMake*, GCC*, etc.
   • clone_patch_build_Caffe.sh - Installs the Caffe* distribution on your machine and patches it with the required adapters from the Model Optimizer.
4. Go to the helper scripts folder and install all the required dependencies:

       cd install_prerequisites/
       ./install_Caffe_dependencies.sh 

5. Install Caffe* distribution. By default it installs the BVLC Caffe* from the master branch of the official repository. If you want to install other version of Caffe*, you can slightly edit the content of the clone_patch_build_Caffe.sh script. In particular, the following lines:

       CAFFE_REPO=https://github.com/BVLC/caffe.git # link to the repository with Caffe* distribution
       CAFFE_BRANCH=master # branch to be taken from the repository
       CAFFE_FOLDER=`pwd`/caffe # where to clone the repository on your local machine
       CAFFE_BUILD_SUBFOLDER=build # name of the folder required for building Caffe* 

   To launch installation, just run the following command:

       ./clone_patch_build_Caffe.sh 

NOTE: In case of problem with the hdf5 library while building Caffe on Ubuntu* 16.04, see the following fix.

Once you have configured Caffe* framework on your machine, you need to configure Model Optimizer for Caffe* to properly work with it. For that, please refer to the Configure Model Optimizer for Caffe* page.
