描述

From issue #1302, it appears autosklearn is a bit unstable when run many times in the same script, i.e. in a for loop.

for i in range(400):
    automodel = AutoSklearn(full_resources)
    automodel.fit(x, y)

We currently have no test for this and it would be good to see if we can reproduce the same connection refused error.

研究方向
Investigate the connection refused error reported in issue #1302. Review existing test files in the repository, particularly those in the 'test' directory, for patterns on how to write stress tests. Write a test that instantiates and fits AutoSklearn models in a loop (e.g., 400 iterations) to see if the error reproduces. Pay attention to resource cleanup between iterations.
