Hi all,

New to Julia, and don’t quite know where to start with this error. Happens when trying to reload all parameters including ODE related parameters with JLD2 load() function.

_Fatal error:_

_ERROR: LoadError: MethodError: no method matching Base.Pairs{Symbol, Union{}, Tuple{}, NamedTuple{(), Tuple{}}}()_

Shortned the error for ease of reading, but I just can’t figure out how to load my parameters back in. The save seemed to work out fine, yet now I can’t access what was saved…

Could you show us the following?

1. The code you used to save the parameter.
2. The code that you used to load the parameters.
3. The full error stack trace.

If you could please include the code and full error stack trace in triple backticks as follows.
