Troubleshooting: 安装CTCDECODE时遇到的ConnectionResetError: [Errno 104] Connection reset by peer

背景

最近在弄一个OCR的课设,其中需要用到实现Beam Search功能的CTC层.由于是使用Pytorch,所以在网上找到了CTCENCODE这个库.本人的环境是:Manjaro+Anaconda+Python3.8.

问题

但是在安装过程中(cd到ctcdecode目录后运行$ pip install .后)遇到了以下报错:

Traceback (most recent call last):

Solution

为了解决这个报错懒癌的我甚至配置完了之前懒得配置的Q2ray,配置了全局代理,但问题仍未解决.这时候我怒了…

灵机一动,$ pip install urllib3,然后再运行$ pip install .问题解决!!!

忙活一上午装了一个包,啥也没做,很开心.
