In order to use the Python plugin provided by ibaVision, Python needs to be installed separately.

Python needs to be installed system-wide, not limited to the user account. The Python installation path needs to be in the system-wide environment variable PATH.

In the Python v3.8 installer, it is at the moment necessary to check the “Add Python 3.8 to PATH” checkbox, otherwise ibaVision won’t be able to use the installation.

When Python has been successfully installed, another requirement is the installation of the numpy package using Python’s package manager “pip”. Without numpy installed, the Python plugin in ibaVision will always report errors.

The easiest way usually is to open a Commandline Prompt or the Powershell and to type

pip install numpy

Depending on the way Python was installed, it may be necessary to run this command with Administrator privileges. It however always requires internet access.
