Maya Python Remote Debugging with PyCharm

  1. Get PyCharm. (Pro required or does free version now support Maya Debugging?)

  2. Setup a PyCharm project to use the Maya Interpreter (File > Settings > Project Interpreter).

  3. Add a Remote Debugging Configuration: Run > Edit Configurations

  • Add > Python Remote Debug
  • Name Configuration
  • Check "Single instance only" ON
  • Set the port (i.e 7720)
  • Uncheck both “Redirect to console Input” and ”Suspend after connect”.

  1. In PyCharm add a break point somewhere and press debug. A progress indicator and "Waiting for connection" shows near the bottom and prints to debug console.

  2. Ensure PyCharm debug is on Maya's Python path, one way is with a Maya startup script:

# <UserDocs>\maya\2016\prefs\scripts\userSetup.py
import sys
sys.path.append('C:\Program Files (x86)\JetBrains\PyCharm 5.0.2\debug-eggs\pycharm-debug.egg')
  1. Connect Maya to the PyCharm debug server using the same port from configuration. PyCharm's "waiting connection" should hide and "Connected to pydev debugger..." prints in debug console.
# Inside Maya Python Console (Tip: add to a shelf button for quick access)
import pydevd
pydevd.settrace('localhost', port=7720, suspend=False)
# To disconnect run:
# pydevd.stoptrace()
  1. Run the script with the breakpoint and hope it will be hit!
