I re-install pymc=5.15.0 and pymc-bart=0.5.12, or pymc=5.15.0 and pymc-bart=0.5.14. It works. But there a new problem has arisen. The calculation is very slow. It used to take 40 seconds, but now it takes 50 minutes. Very strange.
And, it’s very strange that I re-install pymc=5.15.0 and pymc-bart=0.5.14 last night, it not works.
Thank you very much.
