树莓派上Tensorflow js安装问题

Question

我试图让一个节点服务器在树莓派上运行TensorFlow模型我在Ubuntu上做了一个简单的测试，它有效，但它给了我一个错误的树莓

throw new Error("The Node.js native addon module (tfjs_binding.node) can not " +
^
Error: The Node.js native addon module (tfjs_binding.node) can not be found at path: /home/pi/node_modules/@tensorflow/tfjs-node/lib/napi-v8/tfjs_binding.node. 
Please run command 'npm rebuild @tensorflow/tfjs-node --build-addon-from-source' to rebuild the native addon module. 
If you have problem with building the addon module, please check https://github.com/tensorflow/tfjs/blob/master/tfjs-node/WINDOWS_TROUBLESHOOTING.md or file an issue.

这是我要运行的代码

path='file:///home/sa2/work/models/js_model/model.json';


const model = await tf.loadLayersModel(path);
const sum=model.summary();
const test=[]
const prediction = tf.tidy(()=>{
// create a tensor from an input 
const ty = tf.tensor(test).expandDims();
;

// insert a dimension into the tensor's shape 
//const inputTensor = tensor.expandDims();

//execute the infernce for the input tensors
const tensor = model.predict(ty) ;
return tensor.dataSync();
})
export const per = prediction;
console.log(sum);
console.log(per) ;

我试过使用

npm rebuild @tensorflow/tfjs-node --build-addon-from-source

但是不工作

这可能是在树莓派的ARM芯片上运行tfjs时出现的问题。尝试使用引用的命令为RPi重新构建库。

npm rebuild @tensorflow/tfjs-node --build-addon-from-source
