吴恩达C1_W1_Lab03_Model_Representation_Soln运行报错，无法解决

运行吴恩达老师C1_W1_Lab03_Model_Representation_Soln报错，按照几个解决方法我已经把deeplearning.mplstyle文件拷贝到个人安装的目录anaconda3\Lib\site-packages\matplotlib\style下，以及个人jupyter notebook工作目录下，但还是不行，总是提示TypeError: the 'package' argument is required to perform a relative import for './deeplearning'。请大佬给看看

把路径的./去掉就可以了
