It's not computationally singular, just almost singular :) A more reliable check is matrix_rank, which tries to account for roundoff error and gives 15 in this case, which will tell you that there is a problem. Note that rank preserving matrix factorizations tend to be computationally expensive, so are not used by default. Generic Python-exception-derived object raised by linalg functions. … By executing np.linalg.inv(S) I get always an error: The original S is. Compute the (multiplicative) inverse of a matrix. Generic Python-exception-derived object raised by linalg functions. The problem arises due to the perfect correlation between the two series in your data. python矩阵转置和zip(python matrix transpose and zip) 问题 如何获得此矩阵的转置。任何更简单的算法都可以做到这一点。 第一个问题： Input a=[[1,2,3],[4,5,6],[7,8,9]] Expected output a=[[1, … numpy.linalg.LinAlgError¶ exception numpy.linalg.LinAlgError [source] ¶.
