The following is my code

```julia
import Pkg
Pkg.add("GalacticOptim")
using NeuralPDE,GalacticOptim

```

When NeuralPDE is included in the environment package, the following error occurs when GalacticOptim is downloaded, but it can be downloaded when NeuralPDE is removed. I don’t know how to solve this situation. I would be grateful.
