Error test_search

[gazzola]

When I run test_search () it gives error `` AttributeError: Can't pickle local object 'test_search. . ´´

Can you help me solve the problem? Why do you give this error?
How can I solve, do I need some other file?

當我運行test_search（）時，出現錯誤``AttributeError：無法醃製本地對象'test_search。。´´

你能幫我解決問題嗎？ 為什麼會出現此錯誤？
我該如何解決，我需要其他文件嗎？

Maybe the multiprocessing causes this, you can try to set the parameter processes = proc = 1

@gazzola Sorry to be late.
@Hongwei-Wei is right. This problem is due to a limitation of python that lambda function can not be used in multiprocess. The test_search() function is write before i change the grid_search to multiprocess, so i forget to fix it.
There are two solutions. First is to run with only one thread as @Hongwei-Wei said. The second one is replacing the lambda function in "test_search" function into a normal function.
