      I downgraded Nnabla to 1.12.0 and it worked! Thanks a lot for the help!

      Cheers,
      Nic

        Hmmm... while the example (exported it directly from NNC as .onnx and .nnb to ensure that the model works) .onnx -> .nnp -> .nnb now works on the Spresense. However, with Nnabla 1.12.0 my actual PyTorch -> .onnx model can not be converted to .nnp anymore. This is a step that actually worked with Nnabla 1.20.0. I traced this issue back to Nnabla 1.14.0, where PyTorch -> .onnx works again, but the .onnx -> .nnp -> .nnb conversion yields the same error on the MCU as previously stated.

        Is there a workaround for this?

        Best,
        Nic

          Forgot to add error print (and can't edit post anymore):

            @nicibume I have another idea. Please use the latest version of NNabla, but update the NNabla C Runtime Library used by Spresense.

            To do this:

            1. Update NNabla C Runtime Library:
            $ cd externals/nnablart/nnabla-c-runtime
$ git fetch
$ git rebase origin/master
            1. Update nnablart Makefile:

              However, I want to inform you that the urgency of this problem is not too high (at least on my side) ^^
              As my team and I are pursuing a different workaround altogether.

                @niciBume You get these errors because you didn't make the changes I showed in step 2 to the spresense/externals/nnablart/Makefile.

                This adds missing files to the Makefile that were added in the new version of the NNabla C Runtime library.

                You can use the code from step 2 as .patch and apply it to your Spresense SDK repository.

                Best Regards,

                  @kamiltomaszewski oh, my bad. I misinterpreted step 2. Applied the patch and it compiles once again. During inference however, the error is again the same as in:

                  This seems to be a nuttX error message, if I am not mistaking?

                  It actually passes dnn_runtime_initialize but fails at dnn_runtime_forward(), where I trace it back to https://github.com/sonydevworld/spresense/blob/87f81d9c35c7d05d6a75e9177b45d6cbe8d8c063/sdk/modules/dnnrt/src/runtime/runtime_nnabla.c#L186

                  Regarding the conversion, I tied your suggestion, yet with the same result. Would you know the build commands for the NNC?

                  Best,

                  Nic

                    @nicibume Could you please modify the spresense/externals/nnablart/nnabla-c-runtime/src/runtime/runtime.c file as shown below?

                    diff --git a/src/runtime/runtime.c b/src/runtime/runtime.c

                    This adds 2 extra logs. Please send me an output from your serial console after making the change.
