Rspberry Pi 5 & face_attr_resnet_v1_18 with hailo8L

I successfully ran face detection on my Raspberry Pi 5 using TAPPAS 3.31.0 today.

Building on that, when I tried to use face_attr_resnet_v1_18 to extract attributes like gender and age, I received the following error:

terminate called after throwing an instance of 'std::invalid_argument' what(): No tensor with name face_attr_resnet_v1_18_rgbx/fc3

I used the TAPPAS post-processing library libface_attributes_post.so. Is this incorrect?

I am experimenting with this code by referencing this article.
