Any example

[rachit2jain]

Hi, I have been trying to use the library but I am not able to load the model using compileModel. The app just is stuck there and no response is given. Any idea what the problem is? Also, it will be really helpful if you could provide some example code? Thanks in advance!

Can you share a sample of what you are trying to do?

[rhdeck]

Also, not clear what example you are looking for - something beyond the snippet in the readme?

[rachit2jain]

Yes please - a code snippet would be very helpful especially how to load the model.

I am not sure what you mean by load. Maybe if you were to share a snippet of code giving you trouble I could get a frame of reference to help you from.

Load as in compile.

I imported the compileModel from ‘react-native-coreml’

Then I’m trying to compile the model using compileModel command.

import { compileModel } from ‘react-native-coreml’ onClassification = async => { const modelPath = await compileModel(‘../models/xyz.mlmodel’) } It returns me an error - evaluating RNModel.compileModel: undefined is not an object.

To library author, you should state that, the path you need to init the model, is a "ABSOLUTE PATH" instead of a relative path that I think normal user will always expect. This guy obviously pass inside a relative path... @rhdeck @rachit2jain find an absolute path of that model and pass inside, work like a charm

Thank you l! That is helpful. On Thu, Nov 15, 2018 at 5:08 AM Matth3w Lui notifications@github.com wrote:

I would love to know what path was being passed - if there is a common reference point the lib might be able to normalize it.

My suggestion is, add a extra function which allow user to specify a bundle resource since I think it will hit most of the use case. Since on react native abstract level, I think not much user too understand how to play around the sandboxing file system, also, with a local model file but not download on the flight. Also, in the example, I would suggest not to use the "download example" since it's although it imply an absolute path, but maybe it will be better to tell it more explicitly

[rhdeck]

Thank you those are both good advice. Can I ask you to file them as issues so commits can map to them?

Thank you so much guys for your help. I have successfully compiled the model. I am trying to use classifyImage function but I am not getting anything back from the library. So I tried looking into the library and found an EXC_BREAKPOINT error in line let handler = VNImageRequestHandler(ciImage: image!) So I checked the source URL of the image file and it is right. Upon further investigation , the variable image is nil but imageURL is right. I even tried to use guard but still image is nil.

The imageURL is something like this file:///var/mobile/Containers/Data/Application/DE489179-DEFF-4D27-AC2D-1AF1445C6EF1/Library/Caches/Camera/FCB57CD1-6DFF-45FF-B8FA-A09FC77B1C32.jpg

An example app would really help. The instruction in the README leave a lot of room for mistakes, many of which I am apparently making:

I am getting the following error as displayed in the iPhone simulator: TypeError: null is not an object (evaluating 'RNCoreML.mainBundlePath') and the first item in the stack trace point to line 14 in index.js of this project:

const { mainBundlePath, mainBundleURL } = RNCoreML;

Also, I would very much appreciate it if you could provide an example of loading the .mlmodel file from the bundle instead of downloading it from the web.

Thank you very much in advance.

To library author, you should state that, the path you need to init the model, is a "ABSOLUTE PATH" instead of a relative path that I think normal user will always expect. This guy obviously pass inside a relative path... @rhdeck @rachit2jain find an absolute path of that model and pass inside, work like a charm

This should be added to the readme.
