By default, when you use JupyterLab in Amazon SageMaker Studio, you’ll see some Python code being highlighted with pycodestyle syntax check error. This can get distracting if you don’t care about them or have the checks in the CI/CD pipeline already.

Here is how you can disable it:

Disable the pycodestyle check completely

First, click the Settings menu > Settings Editor. There are a lot of items in the Settings Editor. Search for Langauge Servers. Uncheck the pylsp.plugins.pycodestyle.enabled. Now you have a clean notebook.

Disable certain checks

If you only need to disable some rules, here is how you can do it.

Right-click on the line with highlighted code > Show diagnostics panel The diagnostics panel will show up. Right click on the rule you want to ignore > Ignore diagnostics like this > Ignore diagnostics with “EXXX” code.
