I got error when I used matplotlib.pyplot to show image

 5 plt.ylim(-5,6)
 6 plt.title('Question 1(c): sample cluster data (10,000 points per cluster)')
----> 7 plt.show()

C:UsersyashiAnaconda3envsCSC411libsite-packagesmatplotlibpyplot.py in show(*args, **kw)
 242 In non-interactive mode, display all figures and block until
 243 the figures have been closed; in interactive mode it has no
--> 244 effect unless figures were created prior to a change from
 245 non-interactive to interactive mode (not recommended). In
 246 that case it displays the figures but does not block.

C:UsersyashiAnaconda3envsCSC411libsite-packagesipykernelpylabbackend_inline.pyc in show(close, block)
 37 display(
 38 figure_manager.canvas.figure,
---> 39 metadata=_fetch_figure_metadata(figure_manager.canvas.figure)
 40 )
 41 finally:

C:UsersyashiAnaconda3envsCSC411libsite-packagesipykernelpylabbackend_inline.pyc in _fetch_figure_metadata(fig)
 172 """Get some metadata to help with displaying a figure."""
 173 # determine if a background is needed for legibility
--> 174 if _is_transparent(fig.get_facecolor()):
 175 # the background is transparent
 176 ticksLight = _is_light([label.get_color()

C:UsersyashiAnaconda3envsCSC411libsite-packagesipykernelpylabbackend_inline.pyc in _is_transparent(color)
 193 def _is_transparent(color):
 194 """Determine transparency from alpha."""
--> 195 rgba = colors.to_rgba(color)
 196 return rgba[3] < .5

AttributeError: 'module' object has no attribute 'to_rgba'

According to the post,

I updated matplotlib to 2.23 but it still doesn't work. How can I fix it?

I also encountered this situation,that caused by ipykernel versions. I change ipykernel from 4.10.0 to 4.9.0.The problem can be solved.
