运行单元 Python 3.10 需要安装 ipykernel

Question

我刚刚在笔记本电脑上安装了 Python 3.10 (Ubuntu 20.04)。

运行 VS Code 中的 Jupyter Notebook 适用于 Python 3.9，但不适用于 Python 3.10。我收到错误消息：Running cells with 'Python 3.10.0 64 bit' requires ipykernel installed or requires an update.

这是一个愚蠢的错误，我解决了我的问题（参见）。

我试过的东西：

点击重新安装，运行：

/usr/bin/python3.10 /home/joris/.vscode/extensions/ms-python.python-2021.10.1365161279/pythonFiles/shell_exec.py /usr/bin/python3.10 -m pip install -U --force-reinstall ipykernel /tmp/tmp-12568krFMIDJVy4jp.log

运行 pip3 install --upgrade ipykernel jupyter notebook pyzmq（来自线程）。

如评论中所述，这是我单击“重新安装”按钮时的输出：

这是我的 _vendor 文件夹包含的内容：

joris@joris-N751JK:~$ ls /usr/lib/python3/dist-packages/pip/_vendor/
__init__.py  __pycache__

这是重新安装 pip 并检查 _vendor 文件的输出：

joris@joris-N751JK:~$ python3 -m pip install --upgrade --force-reinstall pip

Answer 1

我认为 ipykernel 与 3.10 不兼容。

以下是我尝试使用以下命令安装 ipykernel 时收到的消息：conda install -c anaconda ipykernel

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - ipykernel -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.5,<3.6.0a0|>=3.9,<3.10.0a0']

Your python: python=3.10

解法：

我建议创建一个 virtual environment using conda or another 。

入门指南：

安装Anaconda.
输入以下命令。 [注意：这些是 Windows 命令 - 在 Mac 和 Linux 上可能略有不同。]

# Create virtual environment
# Use a version of Python that is less than 3.10
conda create --name your_env_name python<3.10

# Activate new environment
conda activate your_env_name

# Install ipykernel
conda install -c anaconda ipykernel

# Add this new environment to your Jupyter Notebook kernel list
ipython kernel install --name your_env_name --user

# Windows only: When trying to launch `jupyter notebook`, you may receive a win32api error.
# The command below fixes that issue.
conda install -c anaconda pywin32

Answer 2

我终于找到问题所在了。我在 Python 编码方面相当有经验，但在一般版本处理方面仍远非专业人士。
这里的问题是 ipykernel 需要为您安装的每个新 Python 版本重新安装。因此，解决我的问题的方法很简单：

python3.10 -m pip install ipykernel

Answer 3

我想为此添加评论：

您的解决方案是正确的，但当我在我的新 Linux 上使用它时，它对我不起作用。我做了以下工作来解决问题。

可能有人在使用了以下评论后：

python3.10 -m pip install ipykernel

'distutils.util' 会出错。所以你应该先安装：

sudo apt-get install python3.10-distutils

如果您再次尝试安装，您将收到另一个错误：

ImportError: 无法从 'pip._vendor' 导入名称 'html5lib' (/usr/lib/python3/dist-packages/pip/_vendor/

要解决它你应该使用：

  curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10

最后，最好运行:

 /bin/python3.10 ~/.vscode/extensions/ms-python.python-2022.0.1786462952/pythonFiles/shell_exec.py /bin/python3.10 -m pip install -U notebook /tmp/tmp-5290PWIe78U4HgLu.log
