错误：

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

解决方案：

if __name__=='__main__'://加入此行代码即可
