几周前，我遇到了同样的问题，在尝试过的上百万次尝试中，我能够使它正常工作，但是当时我还不确定我是如何做到的.我现在在新电脑上，问题不会消失.

A few weeks ago I had the same issue and amongst the million things I tried I was able to get it to work, but at the time I wasn't entirely sure how I did it. I'm now on a new computer and the issue won't go away.

推荐答案

nmslib是c++库上的python包装器.因此，它可能会在少数系统上引起问题.我遇到了同样的问题.

nmslib is a python wrapper over a c++ library. Therefore it could cause problems on few systems. I had the same issue.

请从此处克隆存储库，然后手动安装，而不是pip安装.

Please clone the repository from here and install manually instead of the pip installation.

尝试以下操作之一.

1. 根据此处的评论，nmslib是可选的并且仅在将其用于链接程序时才是必需的.因此，您可以从requirements.txt中对其进行注释，然后通过setup.py

1. As per the comments from here,nmslib is optional and is only required if you use it for linker.So you may comment it from the requirements.txt and then do a manual installation via setup.py

或

在您的requirements.txt file顶部，添加numpy并通过setup.py文件安装.

In your requirements.txt file add numpy to the top and install via setup.py file.

尽管上述步骤可能会引发VC ++错误，但将安装scispacy模块，并且可以将其导入.

Though the above steps may throw a VC++ error, the scispacy module will get installed and you will be able to import it.

我尝试了两种解决方案，它们为我工作.

I tried both the solutions and they worked for me.

注意:另外，根据我的评论，我了解到，现在您可以直接使用spacy并加载scispacy模型，前提是您已经下载并安装了这些模型.

Note : Also, from the comments I understand that, now we may directly use spacy and load the scispacy models provided you have downloaded and installed the models.

pip install en_core_sci_sm
import spacy
nlp = spacy.load("en_core_sci_sm")

让我知道哪一个适合您.

Let me know which one works for you.
