for the ROS Navigation in 5 Days Rosject I’ve deleted and reloaded my rosject. Things seem to run OK, however when I try to get visualize by transforms by running rosrun tf view_frames
, I get the usual message about listening to /tf, and then done listening. However then I get the following error:
b'dot - graphviz version 2.43.0 (0)\n'
Traceback (most recent call last):
File "/opt/ros/noetic/lib/tf/view_frames", line 119, in <module>
generate(dot_graph)
File "/opt/ros/noetic/lib/tf/view_frames", line 89, in generate
m = r.search(vstr)
TypeError: cannot use a string pattern on a bytes-like object
No pdf gets generated.
Any suggestions? I can live without it, but it might come in hand for future trouble-shooting.
Thanks,
/K
