Question

我刚刚在Shiny.io上使用keras部署了一个Flexdashboard文本分类器，该分类器据说“成功”了，但在线应用程序不起作用：它链接到仅带有“未找到”的页面。这是完整的应用加载记录：

Application successfully deployed to https://xxxx.shinyapps.io/xxxx/
Warning messages:
1: invalid uid value replaced by that for user 'nobody' 
2: invalid gid value replaced by that for user 'nobody'

我认为该错误与警告消息有关，但是我已经检查了日志，故障点似乎与网状结构有关：

warning: using reticulate but python was not specified; will use python at /usr/bin/python  
Did you forget to set the RETICULATE_PYTHON environment variable in your .Rprofile before publishing?

我检查了本地网状结构使用的python安装：

library(reticulate)
py_config()

然后我编辑了.RProfile使其匹配：

Sys.setenv(RETICULATE_PYTHON = "/Users/xxxx/anaconda3/envs/r-tensorflow/bin/python")

但是当我在Shinyio上部署时，它仍然会产生相同的“未找到”错误。知道如何解决这个问题吗？

在Shiny.io上部署时，请在.Rprofile中设置RETICULATE_PYTHON环境变量
