Keyerror: 'axes.color_cycle Is Not A Valid Rc Parameter (see Rcparams.keys() For A List Of Valid Parameters)'

I am having the error on this line rcParams['axes.color_cycle'] = dark2_colors And below is the traceback. How can I make sure that i fix this issue? Error: ~\anaconda3\lib\site-p

Solution 1:

The parameter is axes.prop_cycle, not axes.color_cycle. However it also needs to be noted that axes.prop_cycle accepts a matplotlib.cycler instance, not a list of colors. So your code should be

import matplotlib

dark2_colors = [(0.10588235294117647, 0.6196078431372549, 0.4666666666666667),
            (0.8509803921568627, 0.37254901960784315, 0.00784313725490196),
            (0.4588235294117647, 0.4392156862745098, 0.7019607843137254),
            (0.9058823529411765, 0.1607843137254902, 0.5411764705882353),
            (0.4, 0.6509803921568628, 0.11764705882352941),
            (0.9019607843137255, 0.6705882352941176, 0.00784313725490196),
            (0.6509803921568628, 0.4627450980392157, 0.11372549019607843),
            (0.4, 0.4, 0.4)]

rcParams['figure.figsize'] = (10, 6)
rcParams['figure.dpi'] = 150
rcParams['axes.prop_cycle'] = matplotlib.cycler(color=dark2_colors)
rcParams['lines.linewidth'] = 2
rcParams['axes.grid'] = True
rcParams['axes.facecolor'] = '#eeeeee'
