При открытии ноутбука Jupyter я получаю следующую ошибку ядра:

Кроме того, когда я запускаю ноутбук Jupyter из Sage, я также получаю ошибку ядра:

Теперь позвольте мне рассказать вам, как именно я установил Jupyter и Sage. Я использую MacOS, поэтому я установил Jupyter с Brew:
pip3 install jupyter
, а затем я установил Sage:
brew install cask
brew cask install sage
Наконец, я установил Sage в Jupyter:
jupyter kernelspec install --user /Applications/SageMath-8.9.app/Contents/Resources/sage/local/share/jupyter/kernels/sagemath
и затем я сделал:
export SAGE_ROOT=/Applications/SageMath-8.9.app/Contents/Resources/sage
Когда я пишу «список спецификаций ядра jupyter», я получаю:
sagemath /Users/inesguimaraes/Library/Jupyter/kernels/sagemath
python3 /usr/local/share/jupyter/kernels/python3
И kernel.json внутри ядра Sageв Jupyter выглядит так:
{"display_name": "SageMath 8.9", "language": "sage", "argv": ["/Users/buildbot-sage/slave/binary_pkg/build/source/SageMath/jc4b6yulaujayb9sr94ia88eourzeqip0oidmas3/local/bin/sage", "--python", "-m", "sage.repl.ipython_kernel", "-f", "{connection_file}"]}
Я знаю, что этот пост действительно длинный и скучный, но может кто-нибудь сообразить, что происходит? Я думаю, что Jupyter не получает вещи, откуда он должен или что-то ... Любая помощь высоко ценится. Заранее спасибо!
