如何在allennlp == 0.3.0下使用JupyterLab？

当我通过浏览器进入jupyterlab时，python内核死了：

notebook_1    |     from prompt_toolkit.shortcuts import create_prompt_application, create_eventloop, create_prompt_layout, create_output
notebook_1    | ImportError: cannot import name 'create_prompt_application'
notebook_1    | [I 18:47:49.552 LabApp] KernelRestarter: restarting kernel (3/5), new random ports
notebook_1    | Traceback (most recent call last):

安装较旧版本的create_prompt_application并没有帮助（这会导致其他问题）。

我在jupyter console存储库中发现了this thread，也许会对您有所帮助。

上述讨论中的一些解决方案。 每个列表条目都是单独的解决方案。

pip install 'prompt-toolkit==1.0.15'
pip install --upgrade ipython

pip uninstall prompt-toolkit 
pip install prompt-toolkit==1.0.15 
pip uninstall jupyter-console 
pip install jupyter-console==5.2.0

只有让iPython恢复运行，对我有用的是   卸载Jupyter，因为当时我不需要它：

删除此人pip uninstall jupyter

卸载有问题的版本pip uninstall prompt_toolkit

删除旧的“损坏版本” pip uninstall ipython

让pip安装首选的依赖项pip install ipython
