Failure to load Mediapipe's Face landmark model on DLPU

We are trying to load the Mediapipe's Face landmark model on the DLPU using the Larod API but we fail to do so with the following error:

And running journalctl

We are however able to load different models like Mediapipe's Face detection model

To reproduce

We're following the same setup as the vdo-larod example, however, we're using CPP. Below is the function where we attempt to load the model

bool setupLarod(const char *modelFile, larodConnection **conn, larodModel **model)
{
    larodError *error = NULL;
    *conn = NULL;
    *model = NULL;
    int larodModelFd = -1;
    const larodDevice *dev = NULL;

    if (!larodConnect(conn, &error))
    {
        std::cout << "Could not connect to larod: " << error->msg << std::endl;
        goto error;
    }

    larodModelFd = open(modelFile, O_RDONLY);
    if (larodModelFd < 0)
    {
        std::cout << "Unable to open model file: " << modelFile << std::endl;
        goto error;
    }

    dev = larodGetDevice(*conn, "axis-a8-dlpu-tflite", 0, &error);
    if (!dev)
    {
        std::cout << "Unable to get device: " << error->msg << std::endl;
        goto error;
    }

    *model = larodLoadModel(*conn, larodModelFd, dev, LAROD_ACCESS_PRIVATE, "", NULL, &error);
    if (!*model)
    {
        std::cout << "Unable to load model: " << error->msg << std::endl;
        goto error;
    }

    close(larodModelFd);
    return true;

error:
    if (larodModelFd >= 0)
    {
        close(larodModelFd);
    }
    if (*conn)
    {
        larodDisconnect(conn, NULL);
    }
    larodClearError(&error);
    return false;
}

And we call it like so

        char modelFile[] = "/usr/local/packages/opencv_app/face_landmark.tflite";
        if (!setupLarod(modelFile, &larodConn, &model))
        {
            std::cout << "setupLarod failed" << std::endl;
            exit(1);
        }

Environment

Axis device model: AXIS M5526-E PTZ Camera
Axis device firmware version: 11.11.73

Additional context

When swapping the device to use the CPU instead, the model is loaded without any issues.

Is this a hardware restriction? Is that operations in the model aren't supported by the DLPU?
