Ethan Welty <ethan.we...@gmail.com> added the comment: I have tried running the script with:
- command line (python <file>): Works without (breaks with) `import _tkinter`. - basic python console (python): Same as with command line. - ipython: Fails with or without `import _tkinter`. However, if for example I make the matrix in the scripts smaller or use only functions that don't resort to multithreading, code runs successfully in parallel in ipython. - IDLE: Perhaps unsurprisingly, the code fails with or without `import _tkinter` (never terminates, or prompts endless "Your program is still running! Do you want to kill it?") Suspecting a problem with Tcl/Tk (Apple's original 8.5.9), I rebuilt python pointing to tcl-tk installed with brew (8.6.8), which I checked with IDLE and _tkinter.TCL_VERSION() / _tkinter.TK_VERSION(). However, this did not fix the problem. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33111> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
