成功解决ImportError: [joblib] Attempting to do parallel computing without protecting your import on a sy
解决问题
ImportError: [joblib] Attempting to do parallel computing without protecting your import on a system that does not support forking. To use parallel-computing in a script, you must protect your main loop using "if __name__ == '__main__'". Please see the joblib documentation on Parallel for more information
解决思路
导入错误：[joblib]试图在不支持分叉的系统上执行并行计算而不保护导入。要在脚本中使用并行计算，您必须使用"if __name__ == '__main__'"来保护主循环。有关详细信息，请参阅并行的joblib文档。
tips：
1、凡是有调用方法的时候，均会出现该错误！
from sklearn.grid_search import GridSearchCV
因为sklearn.grid_search方法已经有所重构！
解决方法
在主程序最顶部加入主代码即可！
if __name__=='__main__': #主程序最顶端，加入此行代码即可哈哈，大功告成！
