[英]Running cells with 'Python 3.9.5 64-bit' requires ipykernel installed or requires an update
[英]Running cells with Python 3.10 requires ipykernel installed
我剛剛在我的筆記本電腦(Ubuntu 20.04)上安裝了 Python 3.10。
在 VS Code 中運行 Jupyter Notebook 適用於 Python 3.9,但不適用於 Python 3.10。 我收到錯誤消息: Running cells with 'Python 3.10.0 64 bit' requires ipykernel installed or requires an update
。
Jalil Nourmohammadi Khiarak 給出了更完整的答案,現在是新接受的答案。
這是一個愚蠢的錯誤,我解決了我的問題(請參閱接受的答案)。
我嘗試過的事情:
/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
pip3 install --upgrade ipykernel jupyter notebook pyzmq

我想為此添加一條評論:
您的解決方案是正確的,但是當我在我的新 Linux 上使用它時它對我不起作用。 我做了以下工作來解決這個問題。
可能是使用以下評論后的人:
python3.10 -m pip install ipykernel
'distutils.util' 會出錯。 所以你應該先安裝:
sudo apt-get install python3.10-distutils
然后再次如果您嘗試安裝,您將收到另一個錯誤:
ImportError:無法從“pip._vendor”導入名稱“html5lib”(/usr/lib/python3/dist-packages/pip/_vendor/
要解決它,您應該使用:
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10
最后,最好運行:
/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
我不認為 ipykernel 與 3.10 兼容。
以下是我嘗試使用以下命令安裝 ipykernel 時收到的消息: 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
解決方案:
為了讓你開始:
# 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
我終於發現出了什么問題。 我在 Python 編碼方面相當有經驗,但在一般的版本處理方面仍遠非專業人士。
這里的問題是需要為您安裝的每個新 Python 版本重新安裝ipykernel
。 因此,解決我的問題的方法很簡單:
python3.10 -m pip install ipykernel
MacOS M1
python -m pip install jupyter notebook -U
使用它並重新啟動 VSCode 即可。
如果您看到此錯誤,也可以使用
Failed to start the Kernel.
The 'python3912jvsc74a57bd0f40663dfee16db09be6af2ff2550db36bd5354ec153147c40353828514dedb99' kernel is not available. Please pick another suitable kernel instead, or install that kernel.
View Jupyter log for further details.
幾天前它工作正常,但好的,這解決了它!
