Interoperability between VPI and PyTorch using the CUDA Array Interface. To wrap up, you define a MainWindow class in the main module. This class is based on PySide2 and provides a graphical user interface for this example. ... It uses OpenCV to read the input video and create an output video frame with twice the height of the input video. This. VPIphotonics partners with public research institutes, industry and universities to develop advanced solutions for the design and optimization of future photonic networks. These activities range from component design to network planning. InPulse - Indium-Phosphide Pilot Line for up-scaled scaled, low-barrier, self-sustained, PIC ecosystem more.
