For using the Python bindings of the OpenCMISS libraries you will need to install:

  • The NumPy library (python-numpy). Basic install instructions are given below, for more detailed instructions read the documentation available from SciPy. To install via pip, first upgrade pip to the latest version:

    python -m pip install --upgrade pip

    Then install for the local user:

    pip install --user numpy
  • [Optional but recommended] The Python virtualenv mechanism for independent Python environments

If you intend to use virtual environments, make sure your target environment is active before proceeding with the following installation steps.

To install the Python bindings, open a command prompt (and activate your virtual environment) and type:

pip install --user <SDK_DIR>/lib/python2.7/(Release|Debug)/opencmiss.iron
pip install --user <SDK_DIR>/lib/python2.7/(Release|Debug)/opencmiss.zinc

Here, SDK_DIR is the installation root of your SDK, and (Release|Debug) refers to the build type. For the current Windows SDK, this path could be for example:

pip install --user <SDK_DIR>\lib\python2.7\Release\opencmiss.iron

for Iron Python bindings or:

pip install --user <SDK_DIR>\lib\python2.7\Release\opencmiss.zinc

for Zinc Python bindings.


If using a virtualenv installation do not use the --user option unless you created the virtual environment using the --system-site-packages option.
