Semshi starts to highlight only after call :PlugInstall

[beatttt]

Semshi did not highlight when I enter the nvim, only starts after I call :PlugInstall command of vim-plug. Anybody knows why?

It might be related to some wrong configuration in your vimrc.

Please try:

• :Semshi when highlight is not working (it should say something like "This is Semshi."
• :Semshi enable

and what does it say?

[beatttt]

When I type :Semshi, it says "This is Semshi". But nothing happens after I type :Semshi enable @wookayin

What is your neovim and python version? What does g:python3_host_prog read?

[beatttt]

Python: 3.9.12

NVIM v0.4.3
Build type: Release
LuaJIT 2.1.0-beta3

It seems like I didn't set the variable g:python3_host_prog. I can't find it in nvim by calling :echo g:python3_host_prog. I added let g:python3_host_prog = '/home/scholar/miniconda3/bin/python' in my init.vim. It didn't work. How should I set it? @wookayin
