2020-05-18 06:34:05 -0500	marked best answer	can't run graph with command rosrun rqt_plot rqt_plot hello! I'm new to this site and ROS I just finished installing ros and wanted to get some graph... so I just typed the command `rqt_plot rqt_plot` this logs got showed up $ rosrun rqt_plot rqt_plot /usr/lib/python2.7/dist-packages/matplotlib/axis.py:1015: UserWarning: Unable to find pixel distance along axis for interval padding of ticks; assuming no interval padding needed. warnings.warn("Unable to find pixel distance along axis " /usr/lib/python2.7/dist-packages/matplotlib/axis.py:1025: UserWarning: Unable to find pixel distance along axis for interval padding of ticks; assuming no interval padding needed. warnings.warn("Unable to find pixel distance along axis " Traceback (most recent call last): File "/opt/ros/kinetic/lib/python2.7/dist-packages/rqt_plot/data_plot/mat_data_plot.py", line 107, in resizeEvent self.figure.tight_layout() File "/usr/lib/python2.7/dist-packages/matplotlib/figure.py", line 1754, in tight_layout rect=rect) File "/usr/lib/python2.7/dist-packages/matplotlib/tight_layout.py", line 349, in get_tight_layout_figure pad=pad, h_pad=h_pad, w_pad=w_pad) File "/usr/lib/python2.7/dist-packages/matplotlib/tight_layout.py", line 128, in auto_adjust_subplotpars fig.transFigure.inverted()) File "/usr/lib/python2.7/dist-packages/matplotlib/transforms.py", line 1775, in inverted self._inverted = Affine2D(inv(mtx), shorthand_name=shorthand_name) File "/usr/lib/python2.7/dist-packages/numpy/linalg/linalg.py", line 526, in inv ainv = _umath_linalg.inv(a, signature=signature, extobj=extobj) File "/usr/lib/python2.7/dist-packages/numpy/linalg/linalg.py", line 90, in _raise_linalgerror_singular raise LinAlgError("Singular matrix") numpy.linalg.linalg.LinAlgError: Singular matrix I don't know why I get this error... I think I installed ROS properly... Could someone please give me a hand to solve this error.. and just nevermind that tags.. I am the first time in here so I don't know how to include tags properly.. My OS is Ubuntu 16.04 and ROS is kinetic and 1.12.14 Thank you for your hand in advance...
