这个问题可能是由于网络问题导致的。Kaggle 服务器无法连接到 PyPI（Python 包索引）服务器以下载 Keras-Bert 库。解决这个问题的一种方法是使用 Kaggle 内置的 Internet 连接。

在 Kaggle Notebook 的右侧栏中，单击“Settings”选项卡，然后打开“Internet”开关。这将启用 Kaggle Notebook 的 Internet 连接，使您可以下载所需的库。

如果您已经启用了 Kaggle Notebook 的 Internet 连接，但仍然遇到此错误，请确保您的代码中正确地指定了要下载的库的名称和版本号。您可以尝试使用以下命令手动安装 Keras-Bert 库：

!pip install keras-bert==0.81.0

此命令将强制安装指定版本的 Keras-Bert 库，即版本号为 0.81.0。您可以根据需要更改版本号。
