Hi All, I have a job running on Jenkins server, which builds python script. The script has to display a bar chart as final output. The build agent I am using on Jenkins appears to have python installed. I confirmed this by adding a build step as python3 —version and the result was: Python 3.6.8. Why then do I have this error showing. Do I need to install a plugin? Kind regards Mari Traceback (most recent call last) File "newjenkins.py", line 7, in <module> import matplotlib.pyplot as plt File "/usr/lib64/python2.7/site-packages/matplotlib/pyplot.py", line 97, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/usr/lib64/python2.7/site-packages/matplotlib/backends/__init__.py", line 25, in pylab_setup globals(),locals(),[backend_name]) File "/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_gtkagg.py", line 10, in <module> from matplotlib.backends.backend_gtk import gtk, FigureManagerGTK, FigureCAnvasGTK, \ File "/usr/lib64/python2.7/site-packages/matplotlib/backends/backend_gtk.py", line 13, in <module> import gtk, gdk = gtk.gdk File "/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py", line 64, in <module> _init() File "/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py", line 52, in _init _gtk.init_check() RuntimeError: could not open display That output indicates that the program is choosing to run Python 2 packages (like gtk) with Python 3. You probably need Python 3 packages to run with Python 3.6.8. Installing a plugin won't help.
