windows - ipython控制台 "Exception [WinError 995] The I/O operation has been aborted"中的错误

Question

我已经在Windows 10计算机上通过Anaconda安装程序安装了python 3.8.5和ipython 7.19.0，并且在导入keras然后运行ls或任何其他命令时，在Ipython中出现以下错误。
当我导入其他命令或运行其他命令时，会发生这种情况。有人可以提出任何解决方案吗？这与最新的python或Ipython有关吗？或者是其他东西。

C:\Users\AA>ipython

这似乎是ipython提示工具包中的错误(版本> = 3)
尝试针对您的环境执行此操作:

conda install prompt-toolkit~=2.0

通常，我们可以通过执行以下操作来解决此问题:

py -m pip install -U prompt-toolkit~=2.0

如果这似乎行不通，则在此处对该错误进行了广泛的讨论，并提供了其他一些解决方案: https://github.com/prompt-toolkit/python-prompt-toolkit/issues/1023#issue-534396318
