2012-10-05 04:36:41 -0500 | answered a question | SMACH tutorial: ImportError: No module named msg Hi .. I had the same problem when I try to run the ./examples/state_machine.py in smach_tutorials package ... There is a file called examples/actionlib.py in the same folder. Rename the file actionlib.py to actionlib1.py and delete the file actionlib.pyc. With that change I could run all the tutorial examples. |
