TypeError: trackerFn(...).registerTensor is not a function

Question

这是我的设置：

节点-v : v12.8.1
Python 3.7.1
系统版本：macOS 10.14.1 (18B75)

Package.json:

"@tensorflow-models/mobilenet": "^2.0.4",
"@tensorflow/tfjs": "^1.6.0",
"@tensorflow/tfjs-node": "^1.2.11",

注意：必须更改为这些设置才能解决

我的文件架构：

** 我的代码：**

const readImage = path => {
  const imageBuffer = fs.readFileSync(path);
  const tfimage = tfnode.node.decodeImage(imageBuffer);
  return tfimage;
}


const performTheImageClassification = async path  => {
    const image = readImage("img_to_predict/actual.jpeg");
     const mobilenetModel = await mobilenet.load();
     const predictions = await mobilenetModel.classify(image);
     console.log('Classification Results:', predictions);
}

终端输出：

Answer 1

我有完全相同的错误，当我试图修复这个错误时，其他错误出现了，这个错误一直持续着。我最终得到了 3 个不同版本的 tfjs tfjs-node 和 mobilenet。

而且我认为这个错误肯定是由版本不匹配引起的。我通过删除 nodemodules 文件夹下的 tensorflow 文件夹 来修复它，然后只是运行

npm i @tensorflow/tfjs @tensorflow/tfjs-node

我特别指出，因为首先我试图通过运行ning npm uninstall 命令只卸载这两个包，然后重新安装它们，但显然在 nodemodules 世界中事情比这更复杂所以你需要卸载整个tensorflow包，因为例如我有一个完全不同版本的tfjs-converter，另一个版本的tfjs-core， tfjs-data 它真的很混乱所以确保你删除了整个 tensorflow 包和运行上面写的命令来安装必要的包。

这将自动安装这两个包的最新版本，当我发布此答案时，它们应该是 1.7.4。现在它对我来说完美无缺，我希望它也对你有用。

这是我的 package.json 如果你想确定的话：

"@tensorflow-models/mobilenet": "^2.0.4",
"@tensorflow/tfjs": "^1.7.4",
"@tensorflow/tfjs-node": "^1.7.4",
