TensorflowJS: TypeError: Cannot read property 'fetch' of undefined

Question

我有一个 angular 7 应用程序，我正在尝试按照 this 示例加载移动网络模型。

我通过运行 npm install @tensorflow/tfjs（按照 this 说明）安装了 tensorflowjs，通过运行 @tensorflow-models/mobilenet.

安装了 mobilenet 模型

之后我通过以下操作导入了移动网络：

import * as mobilenet from '@tensorflow-models/mobilenet';

并执行以下代码以加载模型：

mobilenet.load().then(() => {
     obs.next();
}).catch((err) => {
     console.log(err);
     console.log("ERROR");
});

但我收到以下错误：

TypeError: Cannot read property 'fetch' of undefined
    at new e (tf-core.esm.js:17)
    at browserHTTPRequest (tf-core.esm.js:17)
    at httpRequestRouter (tf-core.esm.js:17)
    at tf-core.esm.js:17
    at Array.forEach (<anonymous>)
    at Function.e.getHandlers (tf-core.esm.js:17)
    at Function.e.getLoadHandlers (tf-core.esm.js:17)
    at Object.getLoadHandlers (tf-core.esm.js:17)
    at e.findIOHandler (tf-converter.esm.js:17)
    at e.<anonymous> (tf-converter.esm.js:17)

有人知道问题出在哪里吗？

Answer 1

我发现问题是我的 packade.json.

上的 @tensorflow/tfs 和 @tensorflow/tfjs-core 有不同的版本

所以，我更改了我的包配置：

...
"@tensorflow/tfjs": "^1.1.2",
"@tensorflow/tfjs-core": "^1.0.2",
...

收件人：

...
"@tensorflow/tfjs": "^1.1.2",
"@tensorflow/tfjs-core": "^1.1.2",
...

然后错误消失了。
