I got this error today when trying to import seaborn today, and I cannot figure out how to address this at all.

I know that I need to open my matplotlibrc file and search for axes.color_cycle but I cannot figure that part out either for the life of me. Really not sure how to resolve this, and any help would be greatly appreciated.

  • You seem to be running a very old version of Seaborn. Current is `0.10.1` – JohanC May 11 '20 at 22:37
  • See also [this post](https://stackoverflow.com/questions/60982373/keyerror-axes-color-cycle-is-not-a-valid-rc-parameter-see-rcparams-keys-for). `color_cycle` has been deprecated long ago and replaced by `prop_cycle`. – JohanC May 11 '20 at 22:41
  • Yeah I think I accidentally installed an old version of Seaborn. I'll try installing the most up to date version, and re-running – timmytam13 May 11 '20 at 22:45

    Does this answer your question?
