Jupyter 笔记本：龙卷风指向不正确的路径答案

【问题标题】：Jupyter notebooks: Tornado pointing to incorrect pathJupyter 笔记本：龙卷风指向不正确的路径

我正在尝试运行 Jupyter 笔记本。我安装了 Python 3.7 版本的 Anaconda 5.3。笔记本启动，但内核无法运行，因为它指向我为一些 ROS 项目安装的另一个版本的 Tornado（输出如下）。如何确保 Jupyter 内核使用安装在 Anaconda 路径中的 Tornado？

【问题讨论】：

您是否考虑过在Anaconda 中使用虚拟环境？？
是的，这是在 Anaconda 中创建环境并采购它之后。

【解决方案1】：

有点晚了，但回答我自己的问题。 PYTHONPATH 是为许多其他项目设置的。由于 conda 没有设置 PYTHONPATH，所以运行

unset PYTHONPATH

成功了。
