NoPdb: Non-interactive Python Debugger
NoPdb is a programmatic (non-interactive) debugger for Python. This means it gives you access to debugger-like superpowers directly from your code. With NoPdb, you can:
- capture function calls, including arguments, local variables, return values and stack traces
- set “breakpoints” that trigger user-defined actions when hit, namely:
- evaluate expressions to retrieve their values later
- execute arbitrary code, including modifying local variables
- enter an interactive debugger like pdb
NoPdb is also a convenient tool for inspecting machine learning model internals. For example, this notebook and this post on Towards Data Science show how to use it to visualize Transformer attention in PyTorch.
NoPdb should run at least under CPython and PyPy. Most features should work under any implementation as long as it has sys.settrace().
