I wanna set solPrint. set\_optimizer\_attribute(model, GAMS.SolPrint(), “0”)  
Do anyone know how to fix this?

The available GAMS options are here: [GitHub - GAMS-dev/gams.jl: A MathOptInterface Optimizer to solve JuMP models using GAMS](https://github.com/GAMS-dev/gams.jl#gams-options).

It doesn’t look like `solprint` is supported.

How about just this?

```julia
set_optimizer_attribute(model, RawOptimizerAttribute("solprint"), 0)

```

No need to set `solprint` to 0, as this is the default for GAMS.jl. Due to the calling context, the following options are hardcoded when calling GAMS from GAMS.jl:

```julia
limrow = 0
limcol = 0
solprint = off
solvelink = 5

```

I’ll add some short info to the GAMS.jl `README.md`.

Changing those options is currently not possible.

When I run the model, the time, node, LP iter, dual bound, primal bound, gap, and compl. show up. I don’t want to have them. Do you know how can I do this?

What do you mean by “[they] show up”? And what’s the problem with them?

You need to add `MOI` to `RawOptimizerAttribute`: `MOI.RawOptimizerAttribute`. Or simply pass the string. Nevertheless, this won’t work for `solprint` as explained above.

My main problem is I want to solve a larg optimization problem, and when the solving process gets started lots of unnecessary imformation is printed and the error excessive output truncated after 524338 bytes pops up. I thought using the solprint may prevent this.

If you are experiencing errors with GAMS.jl, maybe you can share the model (either the JuMP model or the generated GAMS model) and I’ll have a look.

Try `set_silent(model)`.
