【问题描述】：

我正在尝试在我的 react-native-app 中加载 tensorflow.js 模型语音命令。但是在尝试了很多之后，我无法加载模型。我收到此错误

Error: Unable to resolve module `fs` from `node_modules\@tensorflow-models\speech-commands\dist\browser_fft_utils.js`: fs could not be found within the project.

我尝试在主 react-native-app 中添加“fs”模块，但出现此错误-：

Error: While trying to resolve module `fs` from file `...\node_modules\@tensorflow-models\speech-commands\dist\browser_fft_utils.js`, the package `...\node_modules\fs\package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (...\node_modules\fs\index.js`.

我的 package.json 依赖项

"dependencies": {
  "@react-native-community/async-storage": "^1.12.0",
  "@tensorflow-models/speech-commands": "^0.4.2",
  "@tensorflow/tfjs": "^2.3.0",

  "react-native-fs": "^2.16.6",
  "react-native-unimodules": "^0.10.1",
  "util": "^0.12.3"
},

我的 app.js

import React from 'react'
import {Text} from'react-naitve'
import * as tf from '@tensorflow/tfjs';
import '@tensorflow/tfjs-react-native';
import * as speechCommands from '@tensorflow-models/speech-commands';

export default class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      isTfReady: false,
      isModelReady: false
    };
  }

  async componentDidMount() {
    // Wait for tf to be ready.
    await tf.ready();
    // Signal to the app that tensorflow.js can now be used.
    this.setState({
      isTfReady: true,
    });
    this.model = await speechCommands.load()
    this.setState({ isModelReady: true })
  }

  render() {
    return(
      <Text>
        {this.state.isTfReady?<Text>ready</Text>:<Text>no loading///...</Text>}
        Model ready?{' '}
        {this.state.isModelReady ? <Text>Yes</Text> : <Text>Loading Model...</Text>}
      </Text>
    )
  }
}

我试图找出我收到此错误的原因，在GITHUB 上发现了类似的问题，但无法解决问题。

谁能告诉我如何摆脱这个错误？谢谢

【解决方案1】：

我的解决方法是在 node_modules/@tensorflow-models/speech-commands 下的 package.json 中添加以下内容

“浏览器”：{ “fs”：假， “节点获取”：假， “字符串解码器”：假， “加密”：假 },

应该应用https://github.com/tensorflow/tfjs/issues/1274 中的相同解决方案。
