IMX 8M Plus, Not able to run inference on NPU.
Platform = CL-SOM-iMX8Plus
Linux Kernel Release = 5.10.72+gce60d3fa56c9
Using tflite_runtime on python3 to run an inference pipeline on the npu, the pipeline consists of two models (Object Detection + Classifier). Here I'm able to make an Object Detection interpreter with experimental_delegates=libvx_delegate, but when i try to use the same delegate for the Classifier and try to run the inference I get this error:
Traceback (most recent call last):
File "/home/root/.../.../tflite_detection_live.py", line 132, in <module>
main()
File "/home/root/.../.../tflite_detection_live.py", line 110, in main
c_interpreter.invoke()
File "/usr/lib/python3.9/site-packages/tflite_runtime/interpreter.py", line 875, in invoke
self._interpreter.Invoke()
RuntimeError: Node number 66 (Vx Delegate) failed to invoke.
NOTE: The same pipeline runs just fine on the CPU.
Please help resolve this and help run the inference pipeline in such a way that both inferences (Object Detection + Classifier) run on the NPU.
Let me know if you need any more details.
