jupyter中，ModuleNotFoundError: No module named 'lightgbm'

在Jupyter中出现"ModuleNotFoundError: No module named 'lightgbm'"的错误，可能有以下几个原因和解决办法：

1. 虚拟环境中未安装lightgbm模块。首先要确保你已经激活了虚拟环境，然后使用pip命令在虚拟环境中安装lightgbm模块。可以在命令行中执行以下命令：pip install lightgbm。这样就可以将lightgbm模块安装到虚拟环境中了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
