错误:无法安装en-core-web-trf，因为这些包版本有相互冲突的依赖关系。

Question

我使用以下命令(来自spacy网站这里)在Windows10home 64位下安装spacy和en_core_web_trf，但是在运行最后(第三行)命令时遇到了问题。

pip install -U pip setuptools wheel
pip install -U spacy
python -m spacy download en_core_web_trf

错误：

INFO: pip is looking at multiple versions of en-core-web-trf to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install en-core-web-trf because these package versions have conflicting dependencies.

The conflict is caused by:
    spacy-transformers 1.1.4 depends on torch>=1.6.0
    spacy-transformers 1.1.3 depends on torch>=1.6.0
    spacy-transformers 1.1.2 depends on torch>=1.6.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

有人知道怎么解决吗？谢谢!我整晚都被困在这里。

卸载spacy并用pip install spacy-transformers -f https://download.pytorch.org/whl/torch_stable.html重新安装它后发生错误更新

Answer 1

给那些和我有同样问题的人。

上述问题最终没有得到解决，至少我试图重新安装软件包，重新安装python (重新安装之前完全卸载它)。对我没什么用。

我最后是怎么避免这一切的？

我完全卸载了python。

安装Anaconda (最新版本)，在安装Anaconda的同时，也默认安装pip和python。然后，我在windows命令行中使用pip install XX，无论是安装spacy，还是安装requirements.txt，都很好。这就是我是如何避免上述问题的。

希望这对也有这个问题的人有帮助。

Answer 2

尝试：

pip uninstall spacy-transformers 1.1.4

pip uninstall spacy-transformers 1.1.3

pip uninstall spacy-transformers 1.1.2

然后执行：

pip install spacy-transformers -f https://download.pytorch.org/whl/torch_stable.html

您可以在https://pypi.org/project/spacy-transformers/上找到完整的安装过程。
