Relative paths with assemblies calling each other

I have 
parent_dir/HaploDeep/models/some_files.onnx
, 
parent_dir/HaploDeep/HaploDeep.cs
 and 
parent_dir/HaploDeep.Tests/Tests.cs


In 
HaploDeep.cs
 I want to open 
models/files.onnx
 so I do
        private readonly string[] _modelPaths =
        [
            @"models\model_1.onnx",
            @"models\model_2.onnx",
            @"models\model_3.onnx",
            @"models\model_4.onnx",
            @"models\model_5.onnx"
        ];
        // Load them by using the array _modelPaths

but when I call the unit tests it says 
System.IO.IOException: Model file models\model_1.onnx
 does not exists.


I tried to do that:
            string basePath = AppDomain.CurrentDomain.BaseDirectory;
            _modelPaths = [
                Path.Combine(basePath, @"models\model_1.onnx"),
                Path.Combine(basePath, @"models\model_2.onnx"),
                Path.Combine(basePath, @"models\model_3.onnx"),
                Path.Combine(basePath, @"models\model_4.onnx"),
                Path.Combine(basePath, @"models\model_5.onnx")
            ];
            // Load them by using the array _modelPaths

in 
HaploDeep.cs


But then when running my unit tests I have the same, it thinks the relative paths are relative to 
HaploDeep.Tests
 path:
System.IO.IOException: Model file C:\...\HaploDeep.Tests\bin\Debug\net8.0\models\model_1.onnx does not exi...


I've been using Python for years and if a path was relative in library 1, when library 2 would use library 1, the paths would be relative to library 1; not to library 2. And here I'm really confused.
Would really appreciate some help, I've been banging my head on this for the past hour
