+One of your pylint plugins cannot be loaded. There's nothing to change in
+your code, but your pylint configuration or installation has an issue.
+
+For example, there might be a typo. The following config::
+
+    [MAIN]
+    load-plugins = pylint.extensions.bad_biultin
+
+Should be::
+
+    [MAIN]
+    load-plugins = pylint.extensions.bad_builtin
+
+Or the plugin you added is not importable in your environment.

+This warns you that a builtin module was impossible to analyse (an ast node is not pure python).
+There's nothing to change in your code, this is a warning about astroid and pylint's limitations.

+One of your options is not recognized. There's nothing to change in
+your code, but your pylint configuration or the way you launch
+pylint needs to be modified.
+
+For example you might be launching pylint with the following ``toml`` configuration::
+
+    [tool.pylint]
+    jars = "10"
+
+When the following should be used::
+
+    [tool.pylint]
+    jobs = "10"
+
+This warning was released in pylint 2.14: bad options were silently failing before.
