加载spacy模型时出错AttributeError：module'msgpack._unpacker'没有属性'unpack'

Posted 2021-04-18

我在为spacy 2.0.8加载模型时遇到问题，但对于以前的版本2.0.7也是如此。你有什么想法吗？

答案

msgpack刚刚碰到v0.5.5~8小时前。

在Commit da902f9中，unpack函数从msgpack / _unpacker.pyx移动到msgpack init文件。此更改是在最新版本中。

安装msgpack-python v0.5.4现在应该修复它。

另一答案

现在应该解决问题：pip install -U spacy。
