AttributeError: version_info对象没有属性“__version__”

Question

我已经安装了Sci-kit Learn，Numpy，Pandas和Sklearn，但是当我在Pycharm中运行我的脚本时，我得到了这个错误。怎么解决这个问题？所有这些错误意味着什么？

我得到的信息是：

__version__ = __version_info__.__version__
AttributeError: 'version_info' object has no attribute '__version__'

Answer 1

__version__属性不是__version_info__对象的一部分。如果要连接版本字符串，请执行以下操作：

而不是：

__version__ = __version_info__.__version__

尝试：

__version__ = f'{__version_info__}.{__version__}'
