Libulog-py library compile error

Although I have ubuntu18.04 installed on both an arm processor computer and an intel processor computer, I get an error in the libulog-py module when I try to compile it. the whole project is waiting. please help. It cannot find the _ulog.py file that I understand.I’ve been working for 10 days. Can I install it on ubuntu with docker. at least let me set it up that way.
