Thanks for reporting errors.

I think this error doesn't come from FinRL. QUAL_PALETTES is a module inside seaborn. This error could occur due to your unsuccessful installation of the seaborn. It is hard to tell the specific reason. However, I think you can try the following steps and see if the issue can be solved:

  1. Remove the existing package of seaborn and reinstall it.
  2. If 1 doesn't work, create a new virtual environment and reinstall FinRL to use it. (2 is stupid, but it should work.)

By the way, I think you can try to attach codes instead of using texts to report errors. Texts are hard to read.

Hope this helps.
