Thanks @olliw94 for the request! This would definitely be nice to have. We have for now added a similar feature to `tn.ncon`, our contraction routine for tensors. `tensornetwork.contractors.custom_path_solvers.ncon_solver` allows you...

Hi @nquesada, thanks for the issue! This would be a relatively straightforward generalization. Do you have any particular application in mind?

@nquesada a PR is highly welcome! I can help you along the way if neccessary

well, we can always write our own extension if we want

I'll have a look tonight

Sounds good, though I‘d like to investigate why the function doesnt stop once it hits an invariant subspace On Thu, Aug 6, 2020 at 4:06 PM Adam Lewis wrote: >...

@alewis, can you provide me with a minimal example?

The following example works fine for me: ```python import tensornetwork as tn import numpy as np import jax from jax import config config.update('jax_enable_x64', True) be = tn.backends.backend_factory.get_backend('jax') def matvec(x, mat):...

Actually, it turns out that `eigs` (or more accurately `_implicitly_restarted_arnoldi`) has a bug that causes it to return `NaN` in certain cases.

can you send me the code?
