No constructors defined #544

Closed lakshaya17 closed 1 year ago

lakshaya17 commented 1 year ago

I am trying to use Koopman() but getting this error.

MethodError: no constructors have been defined for Any

Some of the types have been truncated in the stacktrace for improved reading. To emit complete information in the stack trace, evaluate TruncatedStacktraces.VERBOSE[] = true and re-run the code.

Can anybody help me with this?

Thanks in advance.

What are you running? Note that DiffEqUncertainty was deprecated for SciMLExpectations a long time ago, and these tutorials were split up into the repos. How did you find this?

Oh I see. I am trying to run a spacecraft dynamical system with uncertainties in the initial condition. I have been following the DiffEqUncertainty module for a while now but never checked the update. Thank you so much. I'll look into it.

Cool, and I realized that we never did a release of this repo's deprecation, so https://docs.sciml.ai/SciMLTutorialsOutput/dev/ that will soon be the stable. Any questions should be on the respective repo.
