pwc-net onnx

PWC-Net is a deep learning model for optical flow estimation, and ONNX is an open format for representing machine learning models. Therefore, it is possible to convert PWC-Net model to ONNX format to make it compatible with different deep learning frameworks. This can be done using tools like ONNX-Tensorflow or ONNX-Caffe2. Once the model is in ONNX format, it can be used for inference in frameworks like PyTorch or TensorFlow.
