Why it tells me the MethodError when I use StochasticPrograms?

[BYS543]

Hi, Martin
I have added the StochasticPrograms package,and use "using StochasticPrograms" ,but when I run the example"farmer" it tells me as following error:

ERROR: LoadError: MethodError: no method matching @stochastic_model(::LineNumberNode, ::Module, ::Symbol, ::Expr)
Closest candidates are:
  @stochastic_model(::LineNumberNode, ::Module, ::Any) at C:\Users\Lenovo\.julia\packages\StochasticPrograms\54439\src\types\stochasticmodel.jl:73
in expression starting at none:1

Also, it has the warning in the command window:
WARNING: both Distributions and JuMP export "shape"; uses of it in module StochasticPrograms must be qualified
How can I deal with it? Thanks a lot!

I am guessing that you are not on the latest version (v0.6.2) that introduced new @stochastic_model syntax. Try updating. If you explicitly run pkg> add [email protected] you can check if there are any dependency blocks. The old anonymous syntax still works as well (check docs for v0.6.1)

[BYS543]

Tkank you for your help, Martin. I have run pkg> add [email protected], and it shows as,

(@JuliaPro_v1.5.4-1) pkg> add [email protected]

When I run the example farmer,it still tells me

[martinbiel]

From the error message it still looks like you are on the wrong version. What is the output of pkg> status? I have never used JuliaPro if it is related to that somehow.

[BYS543]

So it is related to my IDE "JuliaPro"? if I run pkg> status

Everything looks fine, does it not work if you load StochasticPrograms: using StochasticPrograms and copy paste the farmer code into that session?

[BYS543]

Well, I have used ctrl+d to clear the workspace and load StochaticPrograms again ,the new error occurs:

[martinbiel]

Ah, I have not been careful enough with compat. You need to update JuMP to at least v0.21.7.

[BYS543]

So it seems new error occurs after I update JuMP,

[martinbiel]

This is just from running the testfile verbatim. You do not need SPResult. You can just skip the final lines and keep the model definition and the scenarios.

[BYS543]

Thank you very much, Martin. It can fly without errors.

[martinbiel]

Perfect, happy to help!
