I am trying to run the “Universal Differential Equations” demos posted at the github repository: GitHub - ChrisRackauckas/universal_differential_equations: Repository for the Universal Differential Equations for Scientific Machine Learning paper, describing a computational basis for high performanc…

The manifest in the root of the repo says julia 1.7.3, though at 1.7.3 we already had the new manifest format if I’m not remembering wrong so I’m not sure why the manifests inside each example does not have that. But could be worth checking if that works at least. ChrisRackauckas/universal_d…

That manifest is probably for Julia v1.2 or v1.3. Instead of trying to maintain a separate repo like this, I’m working them into the docs of each package. https://docs.sciml.ai/HighDimPDE/stable/ That’s for this, but indeed something weird was added to tracker/base and I need to track that down.

Hi @ChrisRackauckas , The process failed with Julia 1.7.3. So I might indeed have to go down to 1.2 or 1.3 as you suggest. But you are saying that currently one probably has to rewrite the examples from scratch if one hopes to run them on a more recent version of Julia? Given that most of the pac…

Summary Look at package documentation for tested examples, tutorials, and information. The package documentation is the one true canonical source on the state of the package and its versioned. We are still in the middle of redoing some of our documentation ( SciML: Open Source Software for Scientifi…

Thank you for this detailed and helpful reply, @ChrisRackauckas . Just one detail. “Yes, but those scripts are not in tests. I suggest you use the tutorials in the packages. For example: https://docs.sciml.ai/SciMLSensitivity/stable/neural_ode/neural_ode_flux/ It shows the package version.” I d…

[image] erlebach: I did not see a package version at the link you pointed me towards. Could you point it out to me? [Capture29] Every doc is versioned the same like that. Though I guess what you might be wondering is what is the full manifest of the tutorial generator? If that’s your ques…

Thanks. The number you circled is the package number, which is what I asked for, but the version of Julia is also important, isn’t it? One cannot always assume it is the latest version. But as you said, the manifest provides that information. The last link was very informative. I appreciate the time…

[image] erlebach: The number you circled is the package number, which is what I asked for, but the version of Julia is also important, isn’t it? Yes, on the first page of each doc site we should probably put the required Julia versions and link to the blog post explanation. And a way to see t…

Yes, the manifest in folded form would be great. I am finding that when reexecuting the various demos, it is often useful to delete the manifest and instantiate within the package manager, after saving a copy of the manifest of course. But isn’t the Project.toml more important the Manifest.toml sin…

[image] erlebach: One question is this: in Project.toml, the package versions are not listed, but rather there is some kind of hashtag, which is not human-readable. Do you know why this choice was made? The Project.toml doesn’t list the version because that’s the Manifests job. The project fi…
