Error: A JNI error on Arch Linux

[shini-tm]

As arch linux uses pacman instead of app-get, I manually installed jdk8 and maven 3.6.2-1. compiled and attempted to run start_bayou.sh & getting the error:

(venv) [shini@Loki-I build_scripts]$ cd out/
(venv) [shini@Loki-I out]$ ./start_bayou.sh &

^C
[1]+  Done                    ./start_bayou.sh

After pip installing flash, get the same ModuleNotFoundError with tensorflow, after pip installing tensorflow, get the same error with n1tk, after that I get same error with the tensorflow.contrib which can't be pip installed.
