I am using shap package in python to recreate some graphs for my model. One of them is the waterfall chart, which is from the manual I followed generated using the following code(the complete code is too long so please check the manual).
shap.waterfall_plot(shap_explainer_values[4652])
however, the minus sign of my graph is missing with the warning message "Glyph 8722 (\N{MINUS SIGN}) missing from current font."
There are a bunch of questions on stackoverflow related to this problem, all could be solved with
plt.rcParams['axes.unicode_minus'] = False
However, mine couldn't. Could anyone help with this particular question?
I tried shutil.rmtree(matplotlib.get_cachedir()) as well.
