From the profiling tool of xcode ,i found that no nnpack function has been used. And the eigen function has been used. So how can i change the compute mode from eigen to nnpack?

Hi RobertBiehl,
I want to use other models instead of squeeze_net,I clone(git clone) the models from https://github.com/caffe2/models.I use bvlc_googlenet model,and the image is 224*224.But it is Incorrect.
My code below:
do{
// caffe = try Caffe2(initNetNamed: "squeeze_init_net", predictNetNamed:"squeeze_predict_net")
caffe = try Caffe2(initNetNamed: "exec_net", predictNetNamed:"predict_net")
}catch {
...

and my result:

I've tried to install pod as described in repository readme (just adding one string to Podfile), but project fails to get built:

In build settings i see Header Search Paths:

"$(PODS_TARGET_SRCROOT)/lib/caffe2/install/include/"
"$(PODS_TARGET_SRCROOT)/lib/caffe2/third_party/eigen/"

which is resolved by Xcode8.3.1 as /lib/caffe2/install/include and /lib/caffe2/third_party/eigen, which I obviously don't have.

Neither project hierarchy Pods/Caffe2Kit/lib/caffe2 do have such subfolders:

Are not these .h files supposed to be copied together with .a files?
Or I've missed something?

What did you do?

I tried to update my build phases with: libstc++.tdb

What did you expect to happen?

I expected to find that item in the prompt to add a build phase.

What happened instead?

I could not find that item. I think you meant libstdc++.tdb
Maybe update the README?

What did you do?

Added Podfile:
` Uncomment the next line to define a global platform for your project
platform :ios, '10.3'

target 'meh' do
/# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!

/# Pods for meh
pod 'Caffe2Kit', :git => 'git://github.com/RobertBiehl/caffe2-ios'

post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
end

target 'mehTests' do
inherit! :search_paths
/# Pods for testing
end

target 'mehUITests' do
inherit! :search_paths
/# Pods for testing
end

end
`
installed pod.
changed bitcode to no
added libstdc++
added other linker flags of:
-force_load
"$(PODS_ROOT)/Caffe2Kit/install/lib/libCaffe2_CPU.a"

My view controller is same as yours:
`
class ViewController: UIViewController {

@IBOutlet var textView : UITextView!
@IBOutlet var imageView : UIImageView!

var caffe : Caffe2?

override func viewDidLoad() {
    super.viewDidLoad()
    do{
     try self.caffe = Caffe2(initNetNamed: "squeeze_init_net", predictNetNamed:"squeeze_predict_net")
    }
    catch{
    
    }
    let 🌅 = #imageLiteral(resourceName: "lion.png")
    
    if let res = caffe?.prediction(regarding: 🌅) {
        // find top 5 classes
        let sorted = res
            .map{$0.floatValue}
            .enumerated()
            .sorted(by: {$0.element > $1.element})[0...5]
        
        // generate output
        let text = sorted
            .map{"\($0.offset): \(classes[$0.offset]) \($0.element*100)%"}
            .joined(separator: "\n")
        
        print("Result\n\(text)")
        textView.text = text
        imageView.image = 🌅
    }
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
}

override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

let classes = [ has all classes trust me :D    ]

}
`
I copied all the sources like lion.png etc from your git.

What did you expect to happen?

The project should run. Giving me the output just like in tutorial

What happened instead?

Instead I ended up with
[libprotobuf ERROR /Users/Robert/Documents/Workspace/caffe2-swift/lib/caffe2/third_party/protobuf/src/google/protobuf/descriptor_database.cc:57] File already exists in database: caffe/proto/caffe.proto [libprotobuf FATAL /Users/Robert/Documents/Workspace/caffe2-swift/lib/caffe2/third_party/protobuf/src/google/protobuf/descriptor.cc:1272] CHECK failed: generated_database_->Add(encoded_file_descriptor, size): libc++abi.dylib: terminating with uncaught exception of type google::protobuf::FatalException: CHECK failed: generated_database_->Add(encoded_file_descriptor, size):

It happens before the UI even loads.
I have used both simulator and device along with xcode 8 and 9. Although I do realize it is not a problem related to that but still for sanity purposes did that.

I'm a bit new to this, but I'm confused on how to actually import the pod into my project. CocoaPods is installed, but how do I create a podfile and where do I create it?

When build the project always has a issue: Linker command failed with exit code 1. I really do not know how to figure out it. Thanks a lot!!!
