pytorch - Debug jax In vscode - Stack Overflow

Why can't I use a vscode debugger to debug jax code, specifically pure functions. I understand that they provide their own framework for debugging but vscode debugger is quite comfortable. Is this because vscode debugger in the first attempt captures compile time?

You can use vscode interactive debugging – during tracing, which is when the Python part of the code is running. You can't (as far as I know) use vscode interactive debugging during execution of the compiled kernels that the traced code dispatches to.

For more information on JAX's computational model, you could start with JAX Key Concepts: Tracing and continue through the tutorials from there.

JAX provides some specific tools for debugging within this traced computational model; you can read about them at JAX: debugging.
