sciml_train: Strange fatal error with complicated ODE, depends on system dimension

2

I am using a combination of packages to use ANNs within coupled ordinary differential equations. When coupling less than 20 ODEs everything runs smoothly, whereas for more than 20 ODEs...

Clarification: JacVecOperator interface

3

Hi, I'm trying to implement a custom JacVecOperator. In the [docs](https://diffeq.sciml.ai/stable/features/diffeq_operator/#AbstractDiffEqOperator-Interface-Description) it sounds like L(u,p,t) should be multiplication of L with a vector `u`. If `L = Jac(x)` is some...

Requiring parameters to be AbstractVectors

1

I think [here](https://github.com/SciML/DiffEqUncertainty.jl/blob/099d4edc3b400998234dcfabf9177d524201cd92/src/koopman.jl#L28) you are implicitly requiring u0 and p to be AbstractVectors. Hence you might aswell dispatch on that. E.g. this uses tuple parameters and throws an error: ```Julia...

Discontinuous observable

This issue is a follow up to our slack discussion. To compute the size of the basin of attraction I am using a discontinuous observable (`converged`). With the default setting...

Illegal instruction with conda-forge package

1

In the HPC environment (Intel, linux) even very simple script give `Illegal Instruction` errors. This suffices to generate the error ```python model = abess.LinearRegression() model.fit(np.random.rand(2,2), np.random.rand(2)) ``` However, this occurs...

Please indicate. - [x] I am running on an up-to-date [`pypsa-eur` environment](https://github.com/PyPSA/pypsa-eur/blob/master/envs/environment.yaml). Update via `conda...

Instantiating a large model may take quite some time. Is there a way to save an instantiated model to a file? Ideally like `write_to_file` in JuMP. Serializing and deserializing with...

Different transition for a single slide

Is there a way to change the transition type for a single slide? In my presentation I have some erroneous code to show and want to correct it at the...

Correctly enforce existing capacities if build year >= base year

1

## Describe the Bug The baseyear in pypsa-ariadne is 2020. We want to enforce capacities that have been build in 2020 or afterwards. At the moment this is done in...
