Test of different LAPACK functions for computing eigenvalues of a symmetric matrix (corresponding to the routines used by numpy.linalg.eigh and scipy.linalg.eigh, and numpy.linalg.eig) - testcase.cc This article is an extract from Chapter 2 Section seven of Deep Learning with Tensorflow 2.0 by Mukesh Mithrakumar. scipy.linalg.eigh and numpy.linalg.eigh calculates different eigenvalues for a symmetric matrix ! Thank you for providing the script and the dataset. Please provide output of conda list --explicit , as well as your processor type. This notebook is open with private outputs. Outputs will not be saved. You can disable this in Notebook settings Hello all, It seems that the 'eigh' routine from numpy.linalg does not follow the same convention as numpy.linalg.eig in terms of the order of the returned Function Documentation.
Returns two objects, a 1-D array containing the eigenvalues of a, and a 2-D square array or matrix (depending on the input type) of the corresponding eigenvectors (in torch.linalg.eigh (input, UPLO='L', *, out=None) -> (Tensor, Tensor) ¶ Computes the eigenvalues and eigenvectors of a complex Hermitian (or real symmetric) matrix input, or of each such matrix in a batched input. Further, the eigenvalues calculated by the scipy.linalg.eigh routine seem to be wrong, and two eigenvectors (v[:,449] and v[:,451] have NaN entries. The eigenvalues calculated using the numpy.linalg.eigh routine matches the results of the the general scipy.linalg.eig routine as well.

Parameters. a (cupy.ndarray) – A symmetric 2-D square matrix (M, M) or a batch of symmetric 2-D square matrices (, M, M). UPLO – Select from 🐛 Bug I am trying to understand why am I getting different eigenvalues between using numpy.linalg.eigh() and torch.symeig(). To Reproduce An example is as below. jax.scipy.linalg.eigh¶ jax.scipy.linalg.

The current `torch.symeig` uses (on CPU) a different LAPACK routine than NumPy (`syev` vs `syevd`). Even though it shouldn't matter in practice, `torch.linalg.eigh` uses `syevd` (as NumPy does).
