Hello, I'm on a mac m1 and have installed julia with the x86_64 arch. I also have a working python environment using the same arch. I tried building PyCall as...

I'm trying to plot a networkx graph using pyvis version 0.1.8.2. However, the `weight` edge attribute is taken from networkx to pyvis, but it does not have any relevance in...

This PR introduces the `NDM` model for Hilbert spaces with arbitrary local sizes. Say, for instance, that the Hilbert space is that of a two-level system and a three-level system,...

In some paper of @gcarleo I saw that, in order to consider symmetries of a Hamiltonian/lattice, one can bring each sample to a canonical form (e.g. lexicographical order of all...

I have been minimising infidelities for some spin problems using the `ARNNDense` model with complex parameters, but the optimisation is always stuck in some excited state. If I rewrite the...

Closes #1222 This PR includes the `InvalidLossStopping` callback. As mentioned in #1222, I once saw energy going to NaN and back to being finite. Thus, we might want to not...

Sometimes an experiment might produce nan energies during optimisation. However, the optimisation continues. I think it would be best to stop the optimisation because nothing is being optimised.

This PR introduces an experimental feature analogous to the `.expm()` method in qutip, that allows the construction of the `e^{-iA}` for some `LocalOperator` `A`. The implementation is based on approximating...

The current json logger can save parameters each `n` iterations, I think. Sometimes one is only interested in the set of parameters that produced the lowest expected energy, and not...

Is it worth having a reproducibility section in the documentation? I think that as long as one fixes the random seeds in the variational state (pure or mixed), everything should...
