@jnothman Thanks. After modification, the test takes around 0.1s on my PC, only slightly longer than before. In Travis, the test is not among the most time consuming tests. For the default parameter of random forest, n_estimators(10) is small, considering the number of training samples(100) is also small, the execution time seems to be acceptable.

@jnothman Thanks. Corrected. |

Reference Issue
Finish up #9183
proposed by @jnothman
What does this implement/fix? Explain your changes.
I change the regressor used in the test because the result of the regressor is so bad that make the test fail.
Any other comments?
irrelevant test failure due to #9254
