Download of CmdStan failed from GitHub

Hi, I already have cmdstanr working and I saw a message about updating it. Then I encountered this error. Coincidentally, my coworker is trying to install cmdstan for the first time and he is encountering the same error. Please help.

Can you try

install_cmdstan(release_url="https://github.com/stan-dev/cmdstan/releases/download/v2.28.2/cmdstan-2.28.2.tar.gz")

?

>install_cmdstan(release_url="https://github.com/stan-dev/cmdstan/releases/download/v2.28.2/cmdstan-2.28.2.tar.gz")

@rok_cesnovar - any insights?

Can you try running:

utils::download.file(url = "https://github.com/stan-dev/cmdstan/releases/download/v2.28.2/cmdstan-2.28.2.tar.gz", destfile =tempfile(fileext = ".tar.gz"))

The most likely cause is that you are unable to download a file from Github for some reason. The reasons for that can be: firewall issues, you or your organization (if everyone is behind the same IP) hit the rate limit to Github or something else.

The above line should provide us with a bit more info.

This is what I see:

If I download the tar file and store in a folder, is there a command that allows me to install cmdstan using a local tar? Thanks.

Ohhh, I believe AWS is experiencing issues or degraded performance in some locations - https://status.aws.amazon.com ( the URLs in the error message mentions AWS, so I am going to assume Github stores it there).

You can definitely try to download it manually. In that case just store it to the following location:

file.path(cmdstanr::cmdstan_default_install_path(), "cmdstan-2.28.2")

and untar the file there and then call

rebuild_cmdstan()

That’s most likely the cause. AWS is down on my side too. Thx @rok_cesnovar

Hi, I managed to download the 2.28.2.tar.gz manually and untar it in the “cmdstan-2.28.2” folder. But I am still having the following issue. Would you know what the issue is?

>set_cmdstan_path(path = "~/.cmdstanr/cmdstan-2.28.2")
CmdStan path set to: ~/.cmdstanr/cmdstan-2.28.2

If you go to the ~/.cmdstanr/cmdstan-2.28.2 folder, does it have another cmdstan-xyz folder in it?

it should have the bin, src and other folders in it directly.

These are what I see inside the ~/.cmdstanr/cmdstan-2.28.2 folder

$ ls
bin       install-tbb.bat  lib      make      README.md           src   test-all.sh
examples  Jenkinsfile      LICENSE  makefile  runCmdStanTests.py  stan

Hm, that looks fine at first glance. Can you paste the contents of the makefile. Maybe there was an issue when downloading or untarring.

##
# CmdStan users: if you need to customize make options,
#   you should add variables to a new file called
#   make/local (no file extension)
#
# A typical option might be:
#   CXX = clang++
#
# Users should only need to set these variables:
# - CXX: The compiler to use. Expecting g++ or clang++.
# - O: Optimization level. Valid values are {s, 0, 1, 2, 3}.
#      Default is 3.
# - STANCFLAGS: Extra options for calling stanc
##

# The default target of this Makefile is...
help:

-include $(HOME)/.config/stan/make.local  # user-defined variables
-include make/local                       # user-defined variables
"makefile" 351L, 12017C                                                                    2,1           Top

Yeah, that file is broken. It should have 351 files. So either the download failed or the untar was unsuccesful.

It’s solved! I untared wrong. Thank you.
