We're currently using the install-deps script for DIGITS TravisCI builds. It's started failing on me in the last two days with errors like this (but only intermittently?):

$ travis_wait ./scripts/travis/install-torch-wrapper.sh $(pwd)/deps/torch $(pwd)/torch-install-log.txt
Still running (1 of 20): ./scripts/travis/install-torch-wrapper.sh /home/travis/build/lukeyeager/DIGITS/deps/torch /home/travis/build/lukeyeager/DIGITS/torch-install-log.txt

Can we fix this, or do I need to figure out how to use a different Torch install mechanism? The README says the repo is deprecated, but according to this comment the install-deps script should still work:

The install-deps script is still in use, but the rest of the repo is indeed deprecated.
#79 (comment)

This could possibly be an issue on my end, totally unrelated to you. I'm looking into it...

luke, travis builds are famous for flaky network. It's possible that the install-deps script has been partially downloading occasionally. i've noticed the same in some of my contbuilds.

[soumith]

also, have you guys moved to the new travis cluster: https://docs.travis-ci.com/user/migrating-from-legacy/

[lukeyeager]

Thanks for the quick response. I'll just keep restarting builds and hope that things settle down.

Are you talking about moving to trusty? I'd like to, but we depend on BVLC's Travis scripts to install Caffe on Travis and they're not very motivated to switch over from precise - BVLC/caffe#3407. Plus, I've tried to do it myself for Caffe and it's been pretty painful so far.

Have you moved to trusty with Torch? Or are you just talking about using their container/GCE architectures?

[soumith]

I'm talking about their container architectures. I've kept whatever is their default ubuntu install, didn't explicitly move to trusty

[lukeyeager]

From what I've read, you need to turn off sudo to move to the docker-based container architecture (which we can't do), but you get upgraded to GCE automatically if you don't do anything - https://blog.travis-ci.com/2015-11-27-moving-to-a-more-elastic-future.

yea all it takes is to remove all sudo calls. The container architecture is soo nice, the builds are way faster and way less flakier.
