IPython.core.error.UsageError：在启用gui之前，必须提供return_control_callback作为参考

我在Ubuntu16.04上使用PyCharm Community Edition2016.2.3。IPython.core.error.UsageError：在启用gui之前，必须提供return_control_callback作为参考

我配置后显示命令行。当我尝试：

import matplotlib.pyplot as plt

我得到了IPython.core.error.UsageError：

如果我不配置显示coomand线之后，一切工作正常。预先感谢您。

但它真的有效！ – Eugenie

如果升级不起作用，请尝试以下解决方法：

只需取消选中“显示命令行继”对话框中的配置设置。 Ref
