From 5c6674f6eb52f7968b805b25c7478b3d96b6b4f7 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 30 Jan 2023 18:33:50 -0800 Subject: tools: ynl: load jsonschema on demand The CLI script tries to validate jsonschema by default. It's seems better to validate too many times than too few. However, when copying the scripts to random servers having to install jsonschema is tedious. Load jsonschema via importlib, and let the user opt out.
