[英]Jupyter Notebook Cannot Connect to Kernel, Likely due to Zipline / AssertionError
我的所有虚拟环境都运行良好，除了 jupyter notebook 无法连接 kernel 的虚拟环境。 这个环境中有 Zipline，所以我预计那里存在一些问题，即使我使用 Conda 安装了所有软件包。
我在这里阅读了问题和答案，不幸的是，将龙卷风降级到 5.1.1 没有用，也没有收到 ValueErrors。 但是，我收到了一个与 Class NSProcessInfo 相关的 AssertionError。
我在 M1 Mac 上。 来自终端的日志显示以下错误，我的环境文件低于该错误。 有人可以帮我让这个 kernel 工作吗？ 谢谢！

弄清楚了。
什么有效：
# Create environment
conda create -n zipline_env python=3.6 ipykernel
# Activate environment, make sure you can see it in jupyter notebooks
conda activate zipline_env
python -m ipykernel install --user --name=zipline_env
# Install Zipline
conda install -c conda-forge zipline
完成后，您可以 conda 安装其他软件包，如 jupyter、matplotlib 等，并且依赖项对我来说都很好。
为什么：
由于模块名称冲突，Jupyter 笔记本无法连接到 kernel
[英]Jupyter notebook fails to connect to kernel due to module name conflict
当在同一目录中找到“code.py”时，Jupyter notebook 无法连接到 kernel
[英]Jupyter notebook cannot connect to kernel when "code.py" found in same directory
Mac M1 和 Jupyter Notebook 上的 tensorflow_hub 导入错误（很可能是由于循环导入）
[英]tensorflow_hub import error (most likely due to a circular import) on Mac M1 and Jupyter Notebook
无法连接到Azure HDInsight中的Jupyter Notebook服务器
[英]Cannot connect to Jupyter Notebook server in Azure HDInsight
