Operators Running in CPU#
The following table lists the ONNX operators that are not supported by AMD Vitis™ AI NPU. These operators run on the CPU instead of the NPU, creating partitions in the model. If any of these operators is present in the model, only the part of the model containing these operators falls back to CPU execution, while the rest of the model still runs on the NPU.
