Python 安装QuickUMLS时遇到问题

我正在尝试在Python3.7（Ubuntu操作系统）中为医学NLP安装QuickUMLS。我遵循了本网站链接提供的分步安装指南-

但是，在完成安装之后，我无法使用QuickUMLS（）命令实例化matcher对象。弹出以下错误消息

matcher = QuickUMLS(quickumls_fp='/home/dileep/QuickUMLS')

----------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-4-2c04f59d4b93> in <module>
----> 1 matcher = QuickUMLS(quickumls_fp='/home/dileep/QuickUMLS')

NameError: name 'QuickUMLS' is not defined

这表明了这个错误

ERROR: Cannot unpack file /tmp/pip-unpack-s1k8klso/QuickUMLS.git (downloaded from /tmp/pip-req-build-4f1w2qgm, content-type: text/html; charset=utf-8); cannot detect archive format
ERROR: Cannot determine archive format of /tmp/pip-req-build-4f1w2qgm

---

在创建QuickUMLS对象之前，请在代码中执行导入语句：

从quickumls导入quickumls

matcher=QuickUMLS（QuickUMLS_fp='/home/dileep/QuickUMLS'）

ERROR: Cannot unpack file /tmp/pip-unpack-s1k8klso/QuickUMLS.git (downloaded from /tmp/pip-req-build-4f1w2qgm, content-type: text/html; charset=utf-8); cannot detect archive format
