Can’t build this package on x86_64 arch #1

Open wmorgue opened 2 years ago

wmorgue commented 2 years ago

Hello Mark.

On page 29 of your book I could not build the Package of the current repository.

  1. There is error at this line. Did you mean: "wisconsin.mlmodel"?
  2. I can't build the library after launching swift build:

Building for debugging...

This one: ld: symbol(s) not found for architecture x86_64.

I assume that the problem in building the package is in the architecture of the package itself. Did you build this package on a machine with an M1 CPU? I assume the package is built for your current architecture. My macbook is running on an old Intel CPU. I tried to pass the swift build --arch x86_64 flag to the compiler, but it didn't work. No idea yet how to build the package and continue reading the book.

I used an M1 MacBook to write these examples. I will get access to an Intel MacBook and reproduce this problem. Thanks for reporting it.

UPDATE: with updates to CoreML and CreateML, I can no longer use the Apple provided Struct MLDataTable, even adding the new argument for parsing options: https://developer.apple.com/documentation/createml/mldatatable

Apple's new example for training tabular data is a link to an Xcode PlayGround project that does not have any source files in it.

If I can't get this example working with the current Xcode and CoreML libraries, then I will remove this chapter from the book.

I added a warning to the Book that temporarily this example does not work. I hope that the next CreateML library update fixes this. I found some else mentioning this problem also.
