tensorflow.js 实现 官网mnist 代码时出现error Command failed with exit code 1且网页无法连接

按官网的方法只需要四步就可以复现mnist。https://js.tensorflow.org/tutorials/mnist.html

$ git clone https://github.com/tensorflow/tfjs-examples
$ cd tfjs-examples/mnist
$ yarn
$ yarn watch

但是我运行到yarn watch 的时候，报错，error Command failed with exit code 1.

完整错误为：

events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: watch /home/zdzn/tfjs-examples/mnist/node_modules/lodash/fp/transform.js ENOSPC

然后参考这里：https://github.com/facebook/jest/issues/3254

找到解决方法：

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

然后就可以yarn watch 啦！

结果显示：
