I just installed WPy64-3940 that comes with JupyterLab 3.0.14 .
To my surprise, now my code comes decorated with things called "pycodestyle".
As you can see below, the code is underlined in orange and a popup can appear.
I do not like that at all, it perturbs my reading.
Would you know where this comes from and how I can disable this?
Thanks

With JupyterLab in AWS SageMaker Studio, it is enabled by default. Which is annoying as it was not enabled with the previous Studio version, which they renamed Studio Classic. To get rid of the warning messages (some are really annoying and make no sense in a Notebook), I searched the settings. Here is where I was able to disable it:
Settings > Settings Editor > Language Servers
Click on 'pylsp' under 'AVAILABLE'
I then de-selected pylsp.plugins.pycodestyle
I disabled some other options as well, like pylsp.plugins.yapf, and pylsp.plugins.pylint
And I did not need to reload my workspace or anything, the error messages were just gone.

A. Disabling the complete code diagnostics worked to get rid of pycodestyle warnings:
B. There is a json editor shown on the top right of the settings editor that can be used to adapt the settings of the Languageserver.
C. Some aspects that might be confusing:
a) The settings depend on the installed version of jupyterlab-lsp. Update for example with
pip install jupyterlab-lsp --upgrade
pip install 'python-lsp-server[all]' --upgrade
(Installation of a new version might delete your existing user preferences of the language server.)
Documentation of the current configuration style:
https://github.com/krassowski/jupyterlab-lsp#configuring-the-servers
b) When you copy the default settings to the right window, you cannot simply out comment the examples in the doc string to enable them. Instead, the code snippets need to be copied to the right location inside the main element "language_servers" and add some quotation marks around the keys.
c) In some versions, instead of the name "pycodestyle" a different term "pydocstyle" is used in the settings.
d) In some versions, the outdated term "pyls" has not been consistently replaced, yet.
D. Example settings to disable pycodestyle and pyflakes and enable pylint for jupyterlab-lsp version 4.2.0:
{
// Language Server
// @jupyter-lsp/jupyterlab-lsp:plugin
// Language Server Protocol settings.

E: Configure pylint
You can specify the path to a pylint configuration file, for example
"pylsp.plugins.pylint.args": ["--rcfile ../../pyproject.toml"],
This is not a built-in feature of JupyterLab, but an extension called jupyterlab-lsp. As one of the authors I am surprised to see it included by default on the WPy64 distribution, and sorry you don't like it. Here are three potential solutions:
