在尝试运行Handpose tfjs的演示项目时，我遇到了下面的错误。

我的package.json文件包含以下依赖项：

{"name": "tensorflowJs","version": "1.0.0","description": "","main": "index.js","scripts": {  "watch": "cross-env NODE_ENV=development parcel index.html --no-hmr ",  "build": "cross-env NODE_ENV=production parcel build index.html --public-url ./" },"browser": {"crypto": false },"keywords": [],"author": "","license": "ISC","dependencies": {  "@tensorflow-models/handpose": "0.0.4",  "@tensorflow/tfjs-backend-wasm": "^2.0.0",  "@tensorflow/tfjs-converter": "^1.7.4",  "@tensorflow/tfjs-core": "^2.0.0",  "@tensorflow/tfjs-node": "^2.0.0",  "bootstrap": "^4.5.0",  "cross-env": "^7.0.2" },"devDependencies": {  "@babel/cli": "^7.10.1",  "@babel/core": "^7.10.2",  "@babel/plugin-transform-runtime": "^7.10.1",  "@babel/polyfill": "^7.10.1",  "@babel/preset-env": "^7.10.2",  "babel-preset-env": "^1.7.0",  "parcel-bundler": "^1.12.4" }}

注册表的问题本应在0.10.3版本之后得到解决，但即使在版本2中，我仍然面临这个问题。有人知道为什么会出现这个问题吗？

回答：

<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-core"></script><script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-converter"></script><script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-backend-webgl"></script><script src="https://cdn.jsdelivr.net/npm/@tensorflow-models/handpose"></script>

Tensorflow发布了2.0.0版本，现在您必须选择tfjs-backend-webgl、tfjs-backend-cpu或tfjs-backend-wasm中的一个来运行您的模型。您正在使用handpose，因此应该使用webgl。
