有同样的问题，我有juypter和笔记本：

pip install pip-autoremove
    pip-autoremove jupyter -y

    python -m pip uninstall -y jupyter jupyter_core jupyter-client jupyter-console jupyterlab_pygments notebook qtconsole nbconvert nbformat jupyterlab-widgets nbclient jupyter-server-mathjax jupyterlab-code-formatter jupyterlab-lsp nbclassic nbdime jupyterlab-git

字符串
然后重新安装

pip install notebook
    pip install jupyter

型
神奇的是，它工作了，ipywidgets现在在notebook中工作了
