2015-03-13 19:22:58 -0500 | asked a question | ImportError: No module named tf I am writing a node that involves calculating the distance from the PR2's left wrist to a point in space, and publishing that distance. The point is in the base frame, so to make calculations easier I'm attempting to change the frame of the point. However, when I run it, nothing is published (when I use rostopic echo, it indicates that the parameter is not being published. Essentially it doesn't know that it exists). I tried using rosrun on the file and it errors saying Here's what the beginning of my code looks like I've made many modifications but it still does not seem to work (I've checked threads with similar problems but their solutions aren't working). Other files with a similar format work, but mine doesn't... I haven't tried the code without the tf frame, so I'll try that out for now and see if it sheds light on some things. Any suggestions? |
