I got the following errors when I tried to use the train_test_split function. Then I tried to install scipy, but it didn't help. Does anyone know which I might be missing from the error below? Thanks!

I solved this same problem by updating the version of scikit to 0.18.1
I had same problem and solved by importing "Scipy", "Numpy", "Pandas", "Matplotlib" and initially I updated "Scikit-learn".
