@Magic-Bubble ,你好,我是一名推荐系统新手,发现您对推荐系统这本书所复现的代码,非常感谢您的开源!我在复现第二章基于图的模型的代码中,遇到了些许问题,查找很多资料,没有解决不知您是否愿意给出建议?
获取接口函数
r = (1 - alpha) * linalg.inv(eye(len(data)) - alpha * M.T) * r0,这句代码,在运行时会出现“SparseEfficiencyWarning: splu requires CSC matrix format
warn('splu requires CSC matrix format', SparseEfficiencyWarning)”这样的提示,我不太清楚这里出现了什么问题,希望您百忙之中给出些许建议,感谢!!
