PyCharm 使用visdom出错：ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接

环境

win10、pycharm、python3.7、pytorch1.7、Anaconda3、已安装visdom

背景（！！！！重要）

在win10下使用PyCharm，python环境是用Anaconda创建的虚拟环境（我这里命名为pytorch)，里面安装了gpu版的pytorch

报错

ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接

定位错误原因

visdom启动失败，需要激活visdom服务器

解决方法

• 打开Anaconda Prompt（Anaconda3）
• 激活pytorch，输入conda activate pytorch
• 输入python -m visdom.server，但是报错ModuleNotFoundError: No module named ‘jsonpatch’

 (pytorch) C:\Users\hp>python -m visdom.server
Traceback (most recent call last):
  File "D:\Anaconda3\envs\pytorch\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "D:\Anaconda3\envs\pytorch\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "D:\Anaconda3\envs\pytorch\lib\site-packages\visdom\server.py", line 20, in <module>
    import jsonpatch
ModuleNotFoundError: No module named 'jsonpatch'

• 在这里下载jsonpatch-0.8.tar.gz（我的环境下这个版本适用），把它放到你的目录下，例如我放到C:\Users\hp这个路径下，然后输入pip install jsonpatch-0.8.tar.gz

 (pytorch) C:\Users\hp>pip install jsonpatch-0.8.tar.gz

• 输入python -m visdom.server，但是报错ModuleNotFoundError: No module named ‘jsonpointer’

  (pytorch) C:\Users\hp>python -m visdom.server
Traceback (most recent call last):
  File "D:\Anaconda3\envs\pytorch\lib\runpy.py", line 193, in _run_module_as_main

    import jsonpatch
  File "D:\Anaconda3\envs\pytorch\lib\site-packages\jsonpatch.py", line 51, in <module>
    import jsonpointer
ModuleNotFoundError: No module named 'jsonpointer'

• 于是在这里下载jsonpointer-0.7.tar.gz，把它放到你的目录下，例如我放到C:\Users\hp这个路径下，然后输入pip install jsonpointer-0.7.tar.gz

(pytorch) C:\Users\hp>pip install jsonpointer-0.7.tar.gz

• 再次输入python -m visdom.server，成功

(pytorch) C:\Users\hp>python -m visdom.server
D:\Anaconda3\envs\pytorch\lib\site-packages\visdom\server.py:39: DeprecationWarning: zmq.eventloop.ioloop is deprecated in pyzmq 17. pyzmq now works with default tornado and asyncio eventloops.

注意

在上述我的环境中，运行使用visdom的程序时，要在Anaconda Prompt中，先激活pytorch，再激活visdom服务器，并且保持窗口，不能关闭窗口，否则还会报错ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接
具体命令是

• conda activate pytorch
• python -m visdom.server
