I’m currently making a plot in Python using plotnine, and wanted to add text labels to it. To avoid too much overlapping, I decided to use adjust_text alongside geom_text. However, adjust_text does not work, and the program is unable to compile.

I first saw this thread, which advised me to include a dictionary and install the adjustText package. Upon doing both, however, I now get this error:
AttributeError: FancyArrowPatch.set() got an unexpected keyword argument 'expand_points'
My relevant code is as follows:

adjust_text_dict = {
    'expand_points': (2,2),
    'arrowprops': {
        'arrowstyle': '-',
        'color': 'black'
    }
}
plot = (p9.ggplot(quarcs_wr, p9.aes("preanx11", "prepcttotal", label = 'instructor_name')) +
        p9.geom_point(shape = "D", color = "#666799", fill = "#4f82be", size = 4) +
        p9.ggtitle('Mean QuaRCS Pre-Score vs. Mean Anxiety (Measure 1) by Instructor') +
        p9.xlab("Mean Anxiety (Measure 1)") +
        p9.ylab("Percent of Questions Answered Correctly") +
        p9.geom_smooth(method = 'lm', se = False) +
        p9.geom_label(adjust_text = adjust_text_dict)
        )
