No semantic highlight with pylsp

[kalium222]

Hello, I got some problem when working with python environment. Here is how I config relative plugins:

Plug 'prabirshrestha/async.vim'
Plug 'prabirshrestha/vim-lsp'  

" register clangd
if executable('clangd')
    au User lsp_setup call lsp#register_server({
    \ 'name': 'clangd',
    \ 'cmd': {server_info->['clangd', '-background-index']},
 	\ 'whitelist': ['c', 'cpp', 'objc', 'objcpp'],
    \ })
endif

" register pylsp
if executable('pylsp')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'pylsp',
        \ 'cmd': {server_info->['pylsp']},
        \ 'allowlist': ['python'],
        \ })
endif   

" enable sementic highlighting
let g:lsp_semantic_enabled = 1

And I get pylsp by running pip install "python-lsp-server[all]", which should be OK from here.

And here is a comparison with semantic highlight for cpp with clangd.

How to solve this? Thanks.

You would want to look at the logs and see if it is enabled or not. Instructions in readme. Feel free to share the logs if you are still having issues.

The non-verbose log of these two files were similar, so i will show you the verbose version. They are quite long.
In the log for python, the researching result for "semantic" is two, which is much less than that in log for cpp.
Uploading py_v.log…

In comparison, it is log for cpp file: cpp_v.log

in fact i find that the output of :LspSemanticTokenModifer is []. Doesn't pylsp support for semantic tokens?
