Calling Using ReservoirComputing gives the following errors

If I call using ReservoirComputing for a third time it just works.

This is the version I am using

[MartinuzziFrancesco]

This seems to be the same error that occurred in JuliaRegistries/General#30964 that @ChrisRackauckas mentioned to be caused by a IRTools issue

[ChrisRackauckas]

Yes it's an upstream issue with the Zygote/Flux stack.

[MartinuzziFrancesco]

This has been solved since the stable release of Julia 1.6. I'll close the issue
