python-3.x - 加载 spacy 模型时出错 AttributeError : module 'msgpack._unpacker' has no attribute 'unpack'

Question

我在为 spacy 2.0.8 加载模型时遇到问题，但对于以前的 2.0.7 版本也会发生同样的情况。你有什么想法吗？

msgpack 在大约 8 小时前刚刚升级到 v0.5.5。

在 Commit da902f9 unpack函数已从 msgpack/_unpacker.pyx 移至 msgpack init 文件。此更改包含在最新版本中。

安装 msgpack-python v0.5.4 应该暂时修复它。
