问题
今晚,照常打开visdom准备画图观察,然而现实给了我一棒槌......

难道是visdom指令不行?没事,换 python -m visdom.server.结果同上。
尝试方法
- 方法1:使用pip uninstall visdom卸载,再pip install visdom重装,结果依旧如上。
- 方法2:换低版本visdom, pip install visdom==0.1.8,结果依旧如上。
- 方法3:找到出错代码,认真分析出错原因:

注意到这句话。我首先依照路径找到了visdom.server,找到了ioloop的使用,有以下几处:


肯定是这个ioloop出现了问题,报错也说了deprecated嘛,来看看ioloop这个文件,它的install()函数和IOLoop是否正常:



容易发现,调用install()函数和IOLoop都会调用_deprecated(),而这个函数只会返回warning,没有实际用处。
至此可以推断出,visdom版本当中使用的ioloop函数已经在最新的pyzmq中被弃用了,没了。所以,解决方法是安装低版本的pyzmq。(猜测)然而装19版本以下的pyzmq都会失败,理论上要装16版。然后我觉得需要重装python为3.7...... 失败案例。
