Hi all,

I’m trying to run ITensors on the institute cluster, however it only has GLIBC\_2.12 installed. So I’m wondering if there are any versions of ITensors that supports GLIBC\_2.12?

Thanks,

Jacky

What goes wrong when you try to install it?

Thanks for your response! The problem is the following.  
`Pkg.status("ITensors")` returned:

```auto
Status `~/.julia/environments/v1.9/Project.toml`
⌃ [9136182c] ITensors v0.3.57
Info Packages marked with ⌃ have new versions available and may be upgradable.

```

However `using ITensors` returned the following error:

```auto

I see, it seems like maybe it is an issue with `HDF5`.

What happens if you try to install `HDF5.jl` on its own, without installing `ITensors.jl`?

Thanks for checking. Could you raise an issue about this with the `HDF5.jl` package? I think they would have more insight than I can provide.

Since the error is reported during precompilation, does it actually cause problems when you try to run the code?

Perhaps we should make HDF5 an optional dependency of ITensors.jl if it causes installation issues (pinging @miles).

Ok thanks, I will post this to the HDF5 people.

I tried running `using HDF5` on the cluster, and it took more than 20 minutes of wall time without returning anything.

It may be a bit annoying, but something you could do is go through the ITensors.jl source code and remove everything related to `HDF5`, including the dependency requirement in `Project.toml`. The rest of ITensor will work fine without it, it’s only provided for users who want to save and load with that file format.

That’s likely what we will do, and move that code to a package extension or add-on package.

Sounds great, thank you!  
Btw, how soon are we expecting v0.4.0 to be released?

Hi Matthew,

Looks like there’s still a problem. The error message I’m getting from `using ITensors` is almost the same as the original one, with an extra section on NDTensors. Please see below. Thanks a lot!

Thanks for checking this. I see what’s going on, `NDTensors` is still dependent on `HDF5`, so when `ITensors` installs `NDTensors`, it in turn installs `HDF5`. We’ll have to do a similar change to `NDTensors` and move the `HDF5` code into an `NDTensorsHDF5Ext` package extension to make it an optional dependency. @miles

@ARAM-TIME this should be fixed by [[NDTensors] HDF5 package extension by emstoudenmire · Pull Request #1390 · ITensor/ITensors.jl · GitHub](https://github.com/ITensor/ITensors.jl/pull/1390), which is being registered in a new NDTensors v0.3.1 now (so should be ready to download in 15 minutes or so).

Glad to hear it, thanks for the update! It’s definitely nicer to not force users to install HDF5 if they don’t need it.
