No package 'lattice_symmetries' found

[AndyLiuin]

Hello I tried to run the code given and I came across a missing package I can't find, 'lattice_symmetries'. Which package/github repository does it correspond to? Or it could be my problem since I didn't read the code fully yet, appreciate if you can point out. Thanks!

Hello @AndyLiuin! lattice_symmetries module comes from this repo https://github.com/twesterhout/lattice-symmetries. However, if you installed nqs_playground from Conda (i.e. using conda install) or from source but using the provided Conda environments, lattice_symmetries should already be installed. Is that not the case? or did you use a different installation method?

Thanks a lot for your reply! Yes I found the package you're referring to. I built from the source because for some reason it displays Packagenotfounderror with conda install. You may want to look into this?

I'm using a mac by the way.

Ah that explains it I think. Unfortunately, I don't have access to OS X (neither at home, nor at work), and don't build lattice-symmetries Conda package for OS X. Hence, the "package not found" error from Conda. There are a few ways forward, I think:

1. You could try to create a Conda environment based on conda-cpu.yml or conda-gpu.yml depending on whether you have access to a CUDA-capable GPU. You might have to replace gcc_linux-64 and gxx_linux-64 with Clang for OS X. In that environment you then first build lattice-symmetries from source (that should be relatively easy since it compiles fine on OS X). After that you can build nqs-playground from source.

2. You could help out with setting up automatic building of Conda packages in CI. I would be very grateful for it, but I appreciate that it'd potentially require more time than you're willing to spend. With lattice-symmetries Conda package for OS X, building nqs-playground from source should then just work, and if it doesn't I'm happy to fix all OS X specific compilation errors.

3. Or you could try using Linux (most clusters run Linux anyways, and Neural Network-related tasks often require quite a bit of computational resources).
