Cannot run sample program

[adamantinum]

System Information (please complete the following information):

• Model Builder or CLI Version: CLI version installed with dotnet tool install -g mlnet
• Visual Studio Version (if applicable): No Visual Studio

Describe the bug

• On which page of the tutorial did you run into an issue (URL): https://dotnet.microsoft.com/learn/ml-dotnet/get-started-tutorial/consume
• Clear description of the problem: The sample program doesn't run because it searches MLModel.zip in its own folder instead that in the referenced one.

To Reproduce Steps to reproduce the behavior:

1. cd consumeModelApp
2. dotnet add reference "../SampleClassification/SampleClassification.Model/SampleClassification.Model.csproj"
3. Edit Program.cs as explained
4. The error occurs when the command dotnet run is used
5. See error: Unhandled exception. System.IO.FileNotFoundException: Could not find file 'C:\Users\Alessandro\Desktop\myMLApp\consumeModelApp\MLModel.zip'. File name: 'C:\Users\Alessandro\Desktop\myMLApp\consumeModelApp\MLModel.zip' at System.IO.FileStream.ValidateFileHandle(SafeFileHandle fileHandle) at System.IO.FileStream.CreateFileOpenHandle(FileMode mode, FileShare share, FileOptions options) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at System.IO.File.OpenRead(String path) at Microsoft.ML.ModelOperationsCatalog.Load(String filePath, DataViewSchema& inputSchema) at SampleClassification.Model.ConsumeModel.CreatePredictionEngine() in C:\Users\Alessandro\Desktop\myMLApp\SampleClassification\SampleClassification.Model\ConsumeModel.cs:line 37 at System.Lazy1.ViaFactory(LazyThreadSafetyMode mode) at System.Lazy1.ExecutionAndPublication(LazyHelper executionAndPublication, Boolean useDefaultConstructor) at System.Lazy1.CreateValue() at System.Lazy1.get_Value() at SampleClassification.Model.ConsumeModel.Predict(ModelInput input) in C:\Users\Alessandro\Desktop\myMLApp\SampleClassification\SampleClassification.Model\ConsumeModel.cs:line 27 at consumeModelApp.Program.Main(String[] args) in C:\Users\Alessandro\Desktop\myMLApp\consumeModelApp\Program.cs:line 18

Expected behavior Program should run.

Thank you in advance.

@adamantinum Sorry for the delay here. Did you copy the generated MLModel.zip file from the SampleClassification.Model folder to the consumeModelApp folder?

[adamantinum]

Thank you for your reply. Yes, I was able to run the program copying MLModel.zip, but there isn't written in the tutorial, so I suppose it should work without doing it, also because SampleClassification.Model.csproj is referenced in the consumeModelApp project file.

Glad you got it working @adamantinum! I want to make sure our docs are clear. We do have a note about copying the zip, but it seems it isn't noticeable.

Sorry, I'm not trying to call you out! I want to hear if you have feedback on how we make this more clear and understandable.

Oh my fault, it has escaped me. Sorry and thank you for your patience.
