R先知在循环中使Rstudio崩溃 [英] R Prophet crashing Rstudio in loop
问题描述
我已经在Windows的R中使用先知了几个月了，最近开始看到随机的RStudio崩溃.几天前，我没有任何问题.我知道这还不算什么，但我希望有人能够认识到我的系统可能正在发生什么.我注意到，当n.changepoints高于默认值25时，它崩溃的频率更高.
I've been using prophet in R on windows for several months now and have recently started seeing random RStudio crashes. Prior to a few days ago, I was having no issues. I know that's not much to go off of, but I'm hoping someone can recognize what might be going on with my system. I've noticed that it crashes more frequently when n.changepoints is higher than the default of 25.
我看到R 3.4和3.5都崩溃了.我已经正确安装了Rtools，并且可以按 Rstan安装.
I see the crashes on both R 3.4 and 3.5. I have Rtools installed properly and can compile cpp code inline as documented in the Rstan installation.
这是我正在使用的系统中.我有最新版本的先知和Rcpp.
Here is in the system that I'm working on. I have the latest version of prophet and Rcpp.

这是我正在运行的代码.有时(1/5次?)使Rstudio崩溃，并显示会话终止"错误.
Here is the code that I'm running. It sometimes (1/5 times?) crashes Rstudio with a "session terminated" error.
for (i in 1:length(f_names)) {
d <- data_list[[i]]
m <- prophet(df = d,
holidays = h_daily,
n.changepoints = 100,
changepoint.prior.scale = 100)
future <- make_future_dataframe(m, periods = 14, freq = "day")
f <- predict(m, future)
forecast_list[[i]] <- f
}
如果您遇到过类似情况，或者知道我能提供更多信息，请提出建议！
If you've ever encountered something like this or know what I can do to give more info, please advise!
我正在使用Rstudio 1.1.447. Rgui和R命令行中也会发生这种情况.
I'm using Rstudio 1.1.447. This also happens in Rgui and R command line.
推荐答案
当我将其用于每天进行预测时，遇到了相同的情况，尝试每月进行一次预测
I encountered the same when i used it to forecast on daily basis, try to do forecast on monthly basis
make_future_dataframe(m, periods= , freq="month")
对于日常预报，先知套餐无法正常工作
For daily basis forecasting, prophet package is not working properly
