FigureQA的PyTorch实现：ValueError：找不到子字符串

Question

在运行Microsoft（https://github.com/mcogswell/figqa-pytorch）开源项目FigureQA的PyTorch实现时，我收到“ self.server_base_name = server [server.index（“ //”的“ ValueError：未找到子字符串” “）+ 2：]”。它使用visdom config json文件定位服务器，在本例中为localhost。我尝试在本地主机之前添加“ http：//”，但是没有用。任何解决此错误的线索将不胜感激！
