Select the Slicer process and click Attach. The Slicer process should appear in the list below. Here, " slicer" should match the secret specified in enable_attach().
Choose Python remote (ptvsd) as the Transport.In Visual Studio, select Debug > Attach to Process to display the Attach to Process window, then:.The secret parameter specifies a password that must be specified in Visual Studio when connecting to the debugger it may be None.Ĭalling wait_for_attach() blocks Slicer until the debugger attaches.Īlternatively, this code could be added to ~/.slicerrc.py so that it's executed when Slicer starts. Here, calling enable_attach() enables the remote debugging server. Add the following code to the script to enable remote debugging:.In Visual Studio, open the script-the Slicer scripted module-to debug.The PTVS page provides detailed remote debugging instructions. Slicer -launch "C:\D\S4D\python-install\Scripts\pip.exe" install ptvsd Slicer -launch "C:\D\S4D\python-install\Scripts\easy_install.exe" pip To attach to a Slicer's Python instance it's first necessary to install ptvsd, the PTVS remote debugging server, in Slicer's Python environment: Click Apply and make sure that the new environment is selected at the top of the window.The remaining fields should be populated automatically. Add a description, enter the Prefix path to the python-install directory in your build tree, like C:\D\S4D\python-install, then click Auto Detect.Select View > Other Windows > Python Environments to show the Python Environments window.This enables IntelliSense specific to this Python environment. Optional: configure Slicer's Python environment in Visual Studio."Python language support" is part of Visual Studio 2017, and can be added through the installer. PTVS installs as an extension to Visual Studio. Note that as of October 2015 the latest version requires Visual Studio 2013 or Visual Studio 2015. For connecting to VisualStudio manually, follow the instructions described on this page below. To use this extension, follow these instructions. Its remote debugging capability allows attaching the debugger to Slicer's embedded Python environment.ĭebuggingTools extension makes it easy to connect to VisualStudio remote Python debugger from Slicer. On Windows, Python Tools for Visual Studio (PTVS) enables debugging Python inside Visual Studio. 4 Configure the remote debugging server.
