Hi there! I built RL env and trained self-play agents. Now I want to import trained onnx file into CoreML, because app is for iOS users. I read about CoreMLTools but its giving me error: "ModuleNotFoundError: No module named 'coremltools.converters.nnssa". Seems like library is no longer supported. Or maybe there is another way to accomplish my task? Is this even possible to export trained agent from ONNX format into coreML?
