PyCharm - Jupyter Notebooks DLL加载失败:找不到指定的模块

Question

我最近开始在Python中使用PyCharm (PyCharm2020.1.1)，并按照这里给出的说明操作：https://www.jetbrains.com/help/pycharm/jupyter-notebook-support.html#get-started

然而，当我尝试在PyCharm上运行Jupyter笔记本中的任何单元格时，我仍然得到以下错误。我甚至尝试运行一个空的单元格，看看我导入的任何库是否有问题，然而，它仍然抛出了相同的错误：

可能的原因和解决方案是什么？

Answer 1

问题出在'pyzmq‘上

执行以下操作

1. pip卸载pyzmq (您可能会被拒绝，请忽略它)
2. pip安装pyzmq
3. 单击“将此解释器注册为jupyter内核”(由pycharm提示)。

这对我有效，希望对你也有效。:)
