#49942: Problem using IPython3 notebook --------------------------------+-------------------------------- Reporter: jianguohsiang82@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: | --------------------------------+-------------------------------- Comment (by stromnov@…): {{{ File "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4 /site-packages/tornado/ioloop.py", line 57, in <module> import thread # py2 File "/Users/MYNAME/thread.py", line 10 print old, new }}} It's a "name clash" - for some reason your python interpreter imports thread.py from local dir (/Users/MYNAME/thread.py), instead of system one. You can try to run ipython notebook from another directory or adapt import paths. http://python- notes.curiousefficiency.org/en/latest/python_concepts/import_traps.html #the-name-shadowing-trap PS. Yes, you can remove this file entirely, but it can break your local scripts. -- Ticket URL: <https://trac.macports.org/ticket/49942#comment:4> MacPorts <https://www.macports.org/> Ports system for OS X
