Getting started with MLDL frameworks
After your installation is complete, it is time to get started with the machine learning and deep learning (MLDL) frameworks.
General setup
Most of the PowerAI packages install outside the normal system search paths (to /opt/DL/...), so each framework package provides a shell script to simplify environmental setup (for example, PATH, LD_LIBRARY_PATH, PYTHONPATH).
Consider updating your shell rc file (such as .bashrc) to source the wanted setup scripts. For example, run the following command:
source /opt/DL/<framework>/bin/<framework>-activate
To run the test script for a particular framework, run:
<framework>-test
Note about dependencies
A number of the PowerAI frameworks (Caffe-BVLC, Caffe-IBM, TensorFlow, TensorBoard, and PyTorch)
have their dependencies that are satisfied through Anaconda packages. These dependencies are
validated by the <framework>-activate
script to ensure that they are installed
and, if not, the script fails.
For these frameworks, the /opt/DL/<framework>/bin/install_dependencies script must be run before activation to install the required packages.
For example:
source /opt/DL/tensorflow/bin/tensorflow-activate
Missing dependencies ['backports.weakref', 'mock', 'protobuf']
Run "/opt/DL/tensorflow/bin/install_dependencies" to resolve this problem.
