When I dived into code：https://github.com/NVIDIA-Merlin/HugeCTR/blob/main/hps_tf/notebooks/hierarchical_parameter_server_demo.ipynb，I found libhierarchical_parameter_server.so is used in https://github.com/NVIDIA-Merlin/HugeCTR/blob/main/hps_tf/hierarchical_parameter_server/hps_lib.py. I'd like to modify some apis and compile this library for source, but I don't know how to compile this library. After I complied the whole hugectr project, I still can not find this .so file. Can anybody help me？ Thanks in advance.
