pydevd 3.1.0

PyDev.Debugger (used in PyDev, PyCharm and VSCode Python)

PyDev.Debugger

Latest 3.x version: the PyDev debugger now supports sys.monitoring which enables really fast tracing on Python 3.12 (so, if speed is an issue, make sure you upgrade).

The PyDev Debugger is a Python debugger which historically was created to work with PyDev (in Eclipse).

Over the years (as it's open source -- EPL) it was adopted by other IDEs/companies (so, it was integrated into PyCharm and VSCode Python through debugpy, which bundles pydevd).

Note that although it was adopted by other IDEs (and over the years companies of other commercial IDEs did provide backing), by far most of the work was done without any external backing and the ongoing work on the project relies on community support.

So, if you like using it, please consider becoming a backer of the project (this is done through the PyDev umbrella, so please see https://www.pydev.org/about.html for how to contribute to the project).

The sources for the PyDev.Debugger may be seen at:

In general, the debugger backend should NOT be installed separately if you're using an IDE which already bundles it (such as PyDev, PyCharm or bundled through debugpy, which is the debug adapter used in VSCode Python and Visual Studio Python).

It is however available in PyPi so that it can be installed for doing remote debugging with pip -- so, when debugging a process which runs in another machine, it's possible to pip install pydevd and in the code use pydevd.settrace(host='10.1.1.1') to connect the debugger backend to the debugger UI running in the IDE (whereas previously the sources had to be manually copied from the IDE installation).

For instructions on how to Remote Debug with PyDev, see: https://www.pydev.org/manual_adv_remote_debugger.html

pydevd is compatible with Python 3.8 onwards and is tested both with CPython as well as PyPy.

For Python 3.3 to 3.7 please keep using pydevd 2.10.0.

For Python 2 please keep using pydevd 2.8.0.

Recent versions contain speedup modules using Cython, which are generated with a few changes in the regular files to cythonize the files. To update and compile the cython sources (and generate some other auto-generated files), build_tools/build.py should be run -- note that the resulting .pyx and .c files should be commited.
