CI impaired

2018-11-20 Thread Marco de Abreu
Hello,

I'd like to let you know that our CI was impaired and down for the last few
hours. After getting the CI back up, I noticed that our auto scaling broke
due to a silent update of Jenkins which broke our upscale-detection. Manual
scaling is currently not possible and stopping the scaling won't help
either because there are currently no p3 instances available, which means
that all jobs will fail none the less. In a few hours, the auto scaling
will have recycled all slaves through the down-scale mechanism and we will
be out of capacity. This will lead to resource starvation and thus timeouts.

Your PRs will be properly registered by Jenkins, but please expect the jobs
to time out and thus fail your PRs.

I will fix the auto scaling as soon as I'm awake again.

Sorry for the caused inconveniences.

Best regards,
Marco


P.S. Sorry for the brief email and my lack of further fixes, but it's
5:30AM now and I've been working for 17 hours.

Re: [Announce] Upcoming Apache MXNet (incubating) 1.4.0 release

2018-11-20 Thread Steffen Rochel
Thanks Patrick, lets target to get the PR's merged this week.

Call for contributions from the community: Right now we have 10 PR awaiting
merge

and
we have 61 open PR awaiting review.

I would appreciate if you all can help to review the open PR and the
committers can drive the merge before code freeze for 1.4.0.

The contributors on the Java API are making progress, but not all
performance issues are resolved. With some luck it should be possible to
code freeze towards end of this week.

Are there other critical features/bugs/PR you think need to be included in
1.4.0? If so, please communicate as soon as possible.

Regards,
Steffen

soft relu gradient, is it correct?

2018-11-20 Thread Pedro Larroy
I bumped into the definition of the softrelu gradient:

https://github.com/apache/incubator-mxnet/blob/master/src/operator/mshadow_op.h#L170

Which is defined as  1- exp(-x)

As we define the forward of the softrelu as the softplus function,
shouldn't the gradient be the logistic function?

Is my understanding that the gradient of the softrelu should go down
to zero as Lim x -> -Inf  Which is not the case with the above
definition which goes to -Inf as Lim x- > -Inf

Re: MXNet - Gluon - Audio

2018-11-20 Thread Sheng Zha
Hi Gaurav,

The performance concerns is not just around librosa, but also the way to 
integrate it. librosa as a python library requires holding GIL when calling it, 
which makes it hard for asynchronous data preprocessing during training. Also, 
the API design hasn't been verified on the more full-fledged use cases that you 
outlined. That, and based on the lack of expertise of audio processing 
reviewing the design doc, my suggestion is to continue the work as a Gluon 
example, until other use cases are adopted, which is what you started in 
https://github.com/apache/incubator-mxnet/pull/13325. Once you make more 
progress and become more familiar with Gluon design, please report back to this 
thread and I'd be happy to help more on the review.

Thanks, Pedro!

I have also been looking into that issue, but it seems like this would
require changes in the groovy interpreter of Jenkins. From what I can tell,
a refactor will give us multiple benefits (clarity and speed) aside from
resolving this issue.

Re: MXNet - Gluon - Audio

2018-11-20 Thread Gaurav Gireesh
Hi All!
Following up on this PR:
https://github.com/apache/incubator-mxnet/pull/13241
I would need some comments or feedback regarding the API design :
https://cwiki.apache.org/confluence/display/MXNET/Gluon+-+Audio

The comments on the PR were mostly around *librosa *and its performance
being a blocker if and when the designed API can be tested with bigger ASR
models DeepSpeech 2, DeepSpeech 3.
I would appreciate if the community provides their expertise/knowledge on
loading audio data and feature extraction used currently with bigger ARS
models.
If there is anything in design which may be changed/improved that will
improve the performance, I ll be happy to look into this.

Thanks and regards,
Gaurav Gireesh

2018-11-20 Thread Pedro Larroy
I think this is a big problem, which has blocked us before. I want to
point out that you are doing a great thing by avoiding everyone
getting blocked by refactoring the pipelines.

My concern is that we are kicking the can down the road and not
addressing the root cause of the problem with is known

Re: Splitting Jenkins pipelines - stop changes to Jenkinsfiles!

2018-11-20 Thread Marco de Abreu
Hello Steffen,

no, there won't be any impact on the PR process or nightly regressions.
Only the reporting will have to be updated with the new job links, but that
should be a minor issue. To avoid any outage, I have been thinking about
running both versions in parallel.

Best regards,
Marco

Splitting Jenkins pipelines - stop changes to Jenkinsfiles!

2018-11-20 Thread Marco de Abreu
Hello,

we ran into issues around the maximum filesize of the Jenkinsfile a few
times already. In order to resolve this issue, I'd like to combine this
with some refactors I have planned for quite some time.

The idea is basically to move away from one big Jenkinsfile and instead
split it into separate jobs that run in parallel and report their status
individually. Besides avoiding the size restriction, this will greatly
speed up the PR validation process by reducing the critical path. Instead
of having to wait for every single step within a stage to finish before the
next stage (e.g. tests) is getting executed, these pipelines would now be
able to move forward individually. I'm still in the process of refactoring
and can't provide any numbers or documentation at this time, but I would
like to announce this early on to avoid conflicts:

Since I will remove the original Jenkinsfile, this might cause conflicts
with ongoing efforts that try to change the Jenkinsfile. This poses the
risk that I might forget to port a change. Thus, I'd like to ask all
contributors to wait with changes of Jenkinsfile and would like to request
fellow-committers to wait with merging any Jenkinsfile-related PRs until
further notice.

I expect to finish this refactor until the end of the week. Please don't
hesitate to ask if you've got further questions.

Please excuse any caused inconveniences.

Best regards,
Marco


Re: Should PR-860 (Use modernized range loops where possible) be reverted?

2018-11-20 Thread kellen sunderland
Hey Carin, I don't think there's any issues merging this PR.  The veto'd
aspect was around _requiring_ modern loop usage, and failing the build if
clang tidy detected modern loops could be used but weren't.  The original
PR included a check for this and would fail any builds not using modern
loops.  Several people didn't like this aspect so I updated the PR and
removed that overly-strict check.  The current PR doesn't have anything it
in that's been vetod.  We're continuing to warn if clang-tidy detects a
loop could be modernized, but are not causing an error (which was actually
the behaviour before this PR was merged).

Re: Should PR-860 (Use modernized range loops where possible) be reverted?

2018-11-20 Thread Anton Chernov
Hi Carin,

The discussion [1] was about whether to enable automatic checks on using
old behaviour in new PR's. Kellens PR [2] was about modernizing the actual
code itself and was not up for voting, thus could not receive any technical
veto votes.

Per the discussion (as I have understood it), we won't get veto votes if we
would enable the check on CI, if it would be treated as a warning.

Thank you for merging the PR in the first place. I see no reason for
reverting it.

Best
Anton

Re: Should PR-860 (Use modernized range loops where possible) be reverted?

2018-11-20 Thread Pedro Larroy
Hi all

I think we have to make the clear separation between the thread votes
on "uniformly adopting C++11 range loops in the MXNet project" and a
PR which refactored code to be more legible and with improved variable
names.
Merging that PR doesn't imply that we have to uniformly adopt the
previous proposal.  The PR was reviewed and approved by several
people. I would keep the two topics separate, merging this PR doesn't
prescribe any particular idiom for future commits or reviews.

Pedro.

My intent was to be helpful, but I think I may have merged this PR
yesterday too soon thinking it was approved and ready to merge
https://github.com/apache/incubator-mxnet/pull/12356

I didn't see the connected dev discussion
https://lists.apache.org/thread.html/b47f285a80bef47c5ead6c361614e338a0661f6c0c76196c1e3719c5@%3Cdev.mxnet.apache.org%3E
where there were -1 votes, which I believe are vetos?
