Debugger
Use this page to configure Python debug options.
Item | Description |
|---|---|
Attach to subprocess automatically while debugging | If this checkbox is selected, PyCharm will automatically attach all subprocesses of the process being debugged. Thus, if the parent process has subprocesses, their breakpoints will always work. |
Collect runtime types information for code insight | If this checkbox is selected, the types of function calls are preserved during debugging, and passed to the type checker. For more information, refer to Specify types with docstrings. |
Clear caches | Click this button to remove information about the types of arguments, collected at run time. |
Gevent compatible | If this checkbox is selected, the debugger will be compatible with the Gevent-monkeypatched code. You can also enable the Gevent support by setting |
Drop into debugger on failed tests | If this checkbox is selected, PyCharm will stop on every failed test and show the reason for the failure. For more information, refer to Debug failed tests. |
PyQt compatible | If PyQt is installed on the interpreter but is not imported in the application code, some import errors may occur. Deselect this option fixes these errors. If you have multiple PyQt compatible backends installed on your interpreter, you have to select the PyQt or PySide2 backend from the list. By default, the Auto option is enabled, which means that the backend first found will be used. |
For Attach to Process show process with names containing | A string pattern specified in this field will be used to show processes in the Attach to Process list. The default pattern is "python". |
Debugger evaluation response timeout | Use this option to set the maximum time to wait for an evaluation response during debugging. |
On Windows the compiled Cython extensions are bundled with PyCharm.
On Linux and macOS, Cython extensions should be compiled manually in one of two possible ways:
by clicking the link that appears in the warning after the first debugger launch.
by running the command from the warning manually in the terminal. A separate Cython extension should be compiled for each version of Python interpreter.
If someone does not want to use Cython extensions, the environment variable
PYDEVD_USE_CYTHON=NOshould be passed.
