requests.exceptions.ConnectionError: HTTPConnectionPool(host=‘localhost‘, port=8123): Max retries ex

一、前言:

在一次运行代码的到时候,突然爆出一长串的错误:

  File "/home/wyc/software/anconda3/envs/pytroch_test/lib/python3.9/site-packages/requests/adapters.py", line 519, in send
    raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=8123): Max retries exceeded with url: /env/main (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused'))
[Errno 111] Connection refused

这个是因为visdom.server未启动的原因。

解决方法:

python -m visdom.server

注意:python多环境的情况下,需要在相应的代码运行的环境下面启动。

二、可能出现的问题:

第一次启动需要下载配置文件,由于来自github上面,所以可能不能下载成功,报错内容如下:/home/wyc/software/anconda3/envs/pytroch_test/lib/python3.9/site-packages/visdom/server.py:39: DeprecationWarning: zmq.eventloop.ioloop is deprecated in pyzmq 17. pyzmq now works with default tornado and asyncio eventloops.
  ioloop.install()  # Needs to happen before any tornado imports!
Checking for scripts.
Downloading scripts, this may take a little while

解决办法:

1. 使用梯子科学上网,GitHub - kuweicai/document-sharing 下载该链接下的文件,

将下载好的文件里面的 static,覆盖代码环境下面的文件

博主的路径如下:

/home/wyc/software/anconda3/envs/pytroch_test/lib/python3.9/site-packages/visdom/static

2. 修改server.py文件,第117行,将该行注释掉就行了:

/home/wyc/software/anconda3/envs/pytroch_test/lib/python3.9/site-packages/visdom/server.py

三、成功解决:

再次运行,启动服务的代码:python -m visdom.server,出现西面的返回信息就代表,成功了
