I encountered an error while experimenting with the new CreateMLComponents in playground with the following code: import CreateMLComponents import CoreML var fullyConnected = FullyConnectedNetworkRegressor<Float>.init() fullyConnected.hiddenUnitCounts = [2] let feature: AnnotatedFeature<MLShapedArray<Float>, Float> = .init(feature: .init(scalars: [2, 3], shape: [2]), annotation: 5) let fitted = try? await fullyConnected.fitted(to: [feature, feature]) print(fitted) The generated error message is included (partially) at the end of this post. I later found out that this same code works fine in an actual app. Any insights? The error message: Playground execution failed: error: Execution was interrupted, reason: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0). The process has been left at the point where it was interrupted, use "thread return -x" to return to the state before expression evaluation. * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)   * frame #0: 0x00007ffb2093728d SwiftNN`SwiftNN.Tensor.scalar<œÑ_0_0 where œÑ_0_0: SwiftNN.TensorScalar>(as: œÑ_0_0.Type) -> œÑ_0_0 + 157     frame #1: 0x00007ffb20937cbb SwiftNN`SwiftNN.Tensor.playgroundDescription.getter : Any + 91     frame #2: 0x000000010da43ac4 PlaygroundLogger`___lldb_unnamed_symbol491 + 820     frame #3: 0x000000010da45dbd PlaygroundLogger`___lldb_unnamed_symbol505 + 189 (some more lines ...)
