The environment uses the Anaconda Distribution for Python, which contains source-built Python and libraries, provided directly from Anaconda. The Python code can access data through the references via the built-inxl()function as part of a Python formula. This means that Python formulas have access...
The latest VTK wheels are available on all the major platforms (Windows, MacOS, and Linux). If you are out of luck, and your platform is not supported then you will need to install VTK yourself using your particular distribution as discussed in theGeneral Build and Installation instructions ...
The integration of the Anaconda Distribution for Python in Microsoft Excel is more than a feature; it’s a redefinition of what’s possible within data analytics. It combines Python’s advanced capabilities with Excel’s familiar interface, bridging the gap between high-powered data science and ev...
