带有spaCy的未定义符号PyFPE_jbuf

Question

我现在在Ubuntu 17.10上尝试import spacy时得到undefined symbol: PyFPE_jbuf 。

>>> import spacy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/spacy/__init__.py", line 4, in <module>

    from .functoolz import *
ImportError: /usr/local/lib/python2.7/dist-packages/cytoolz/functoolz.so: undefined symbol: PyFPE_jbuf

这是在Python 2.7中，而Python 3.6可以正常工作。 我（至少）有spaCy 2.0.5和2.0.6的问题。

已经报告了许多其他项目的PyFPE_jbuf错误，例如sklearn（ https://bugs.launchpad.net/ubuntu/+source/scikit-learn/+bug/1716004 ），numpy（ numpy未定义符号：PyFPE_jbuf ）和lxml（ 未定义符号：在ubuntu上使用'lxml'时发生PyFPE_jbuf错误 ）。 这里的一般建议似乎是重新安装。 我的sklearn，numpy和lxml导入工作正常。

我努力了

pip install --upgrade spacy

和

pip uninstall spacy
pip install spacy

这些命令无济于事。

Answer 1

我自己修好了。 强制重新安装包括依赖项似乎可以正常工作：

$ sudo pip install --upgrade --force-reinstall spacy

SpaCy现在可以导入：

$ python2
Python 2.7.14 (default, Sep 23 2017, 22:06:14) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import spacy
>>> 

的升级cytoolz与sudo pip install --upgrade cytoolz中也只有解决这个问题cytoolz 。 一个新的异常出现了preshed 。
