当你在使用NumPy的线性代数模块(numpy.linalg)时遇到 LinAlgError: array must not contain infs or nans 错误,这通常意味着你试图对一个包含无穷大(inf)或不是数字(nan)的数组执行某些操作,而这些操作是不允许的。以下是根据你的提示,分点解答如何解决这个问题: 确认数组中是否存在无穷大(inf)或非数字(nan)值...

尝试在python中对数组进行线性回归,我不断得到错误“array must not contain infs or nans”没有inf或nan
Causes of “ValueError: array must not contain infs or nans” The “ValueError: array must not contain infs or nans” occurs when we perform certain operations or functions on an array that consists ofNaNorInf values. Some common causes of this error are the following: Performing mathematical...
LinAlgError: Array must not contain infs or NaNs 用python做谱聚类,开始的时候选择目标函数用Min cut方法,一切正常,聚类效果不错;然后用Nomarlized cut,聚类空手道网络的时候也一切正常,聚类自己计算的一个课程相似度网络的时候开始报错: 。换用Min cut就没有问题,而Nomarlized cut相比Min cut只多了对划分平衡...
ValueError: array must not contain infs or NaNs 参考github对应库的issues进行解决,https://github.com/scikit-learn/scikit-learn/issues/18138,第一次fit在try里面运行,第二次就成功fit。: try: pca.fit(train_X)except: pca.fit(train_X)
