python - 代码在 Google Collab 中运行，但不在本地机器 python 上运行

问题描述

我正在运行一个 TensorFlow 模型，当我尝试在 google collab 上运行它时它运行良好，但是如果我在本地机器上运行相同的代码，它会给我以下错误：

C:\Users\Shaikh Abuzar\AppData\Local\Programs\Python\Python37\lib\site-packages\tensorflow\python\keras\callbacks.py:1472: RuntimeWarning: invalid value encountered in less
  if self.monitor_op(current - self.min_delta, self.best):

如果有人可以帮助我，那就太好了。 https://colab.research.google.com/drive/1kQ2KeiSXEbLRJ3tooJ8A6-tg0oqmNBRR?usp=sharing
