| tkaczynski | hi | 15:00 |
| vincentfrancoise | hi | 15:04 |
| tkaczynski | hi vincent-bot :) | 15:05 |
| *** jed56 has quit IRC | 15:05 | |
| vincentfrancoise | lol | 15:05 |
| tkaczynski | I am just wondering... I will be pushing some next changes related to scoring module soon | 15:05 |
| vincentfrancoise | I saw you pushed a new patchset earlier on | 15:06 |
| tkaczynski | I plan to also add a sample scoring engine. it could be a real thing and for example use some ML framework | 15:06 |
| tkaczynski | (yes, I did - nice that you've noticed) | 15:06 |
| vincentfrancoise | with the uuid field id/uuid/name field combo ^^ | 15:07 |
| tkaczynski | yes!!! | 15:07 |
| tkaczynski | I gave up after hitting the wall with updates/soft deletes | 15:07 |
| tkaczynski | anyway, I have a different question: do you think it's a good idea to add some Machine Learning framework to Watcher? | 15:08 |
| vincentfrancoise | aren't scoring engines capable of doing some machine learning? | 15:09 |
| tkaczynski | for example scipy package. but it's quite large (39 MB compressed) and it's another dependency not strictly needed | 15:09 |
| *** thorst_ has quit IRC | 15:09 | |
| vincentfrancoise | oh, I believe this is up to the strategy developer to add extra Python dependencies to his strategy if need be | 15:10 |
| vincentfrancoise | in his own 3rd party project | 15:10 |
| tkaczynski | well, yes :) but they need to be implemented first :) you can implement for example a neural network yourself if you like... or you can use a library which some smart folks already did | 15:10 |
| tkaczynski | sure, but then the example scoring engine will be probably very simple and won't use any ML | 15:11 |
| vincentfrancoise | yeah but all I'm saying is that this scipy dependecy would lie in the 3rd party alongside the 3rd party strategy and not in watcher | 15:11 |
| vincentfrancoise | of course we shouldn't re=invent the wheel | 15:12 |
| vincentfrancoise | re-invent | 15:12 |
| tkaczynski | kind of like a dummy strategy - just implementing the interface, showing up in the CLI and API | 15:12 |
| vincentfrancoise | that being said | 15:12 |
| vincentfrancoise | if we want to provide a machine learning based strategy within Watcher | 15:12 |
| *** diga has quit IRC | 15:12 | |
| vincentfrancoise | then the question of this dependency makes more sense to me | 15:13 |
| tkaczynski | yes, but we are not doing it yet. my change is simply creating a framework for plugins, nothing more. at this moment I don't have plans to implement any real strategy using scoring engines / ML | 15:14 |
| tkaczynski | sorry, I did say the full truth - I will do that, but as a 3rd party (intel) plugin | 15:14 |
| tkaczynski | I was just wondering if anybody would like to see some real scoring engine being built-in in watcher | 15:15 |
| tkaczynski | or just a dummy thing doing nothing | 15:16 |
| vincentfrancoise | I guess having a fully functioning sample using the scoring engine would make a lot of sense | 15:16 |
| *** hvprash has joined #openstack-watcher | 15:16 | |
| vincentfrancoise | so yeah maybe you can create another dummy-ish strategy using it then | 15:17 |
| tkaczynski | well the dummy one also can be made functional - it can for example calculate the maximum value from a given array ;) then there are no additional dependencies etc. | 15:17 |
| tkaczynski | or I could try to come up with some more complicated data model and use a library like scipy to implement it, but the facts are that this one might also not be very useful | 15:18 |
| tkaczynski | as creating a good data model is a job on its own and can take months! | 15:18 |
| *** thorst_ has joined #openstack-watcher | 15:18 | |
| *** hvprash_ has joined #openstack-watcher | 15:19 | |
| vincentfrancoise | the only rule for the current dummy is that it should not need to call any external sevice to keep it a simple test case in our integration test | 15:19 |
| vincentfrancoise | so maybe you can add a strategy parameter that can turn on a scoring engine functionality in it (that would be deactivated by default) | 15:20 |
| *** hvprash has quit IRC | 15:20 | |
| tkaczynski | I actually created one more strategy called dummy_with_scorer, which is supposed to use some dummy_scorer - so that the whole thing can be tested and also serve as an example how to implement a strategy using some scoring engine | 15:21 |
| vincentfrancoise | sounds good to me then | 15:23 |
| tkaczynski | I was just thinking whether there is any expectation for this dummy_scorer to be any "intelligent" | 15:23 |
| *** hvprash_ has quit IRC | 15:23 | |
| *** thorst_ has quit IRC | 15:23 | |
| vincentfrancoise | hmmm | 15:23 |
| vincentfrancoise | Did you discuss it yesterday at the midcycle? | 15:23 |
| tkaczynski | unfortunately no, maybe I can just ask this question quickly... | 15:24 |
| tkaczynski | today | 15:24 |
| vincentfrancoise | because I do not personally have a clear answer to this | 15:24 |
| tkaczynski | because I think there is no clear answer :) | 15:25 |
| vincentfrancoise | jed56 or acabot seem better placed than me on what is expected or not | 15:25 |
| tkaczynski | ok, I will try to reach them out. if not today, then some other time | 15:25 |
| vincentfrancoise | but IMHO, the more we can show to anyone trying watcher, the better | 15:26 |
| tkaczynski | sure, this is my intention. but adding a big dependency always has a cost. who knows, maybe adding this scipy package can cause some unrelated problems for watcher etc. | 15:27 |
| vincentfrancoise | At some point | 15:28 |
| tkaczynski | this is why it's not a clear winner, because the scoring engine won't be that useful even with that package (I don't have time to work on the data model full time) | 15:28 |
| tkaczynski | ... and I'm not a data scientist :) | 15:29 |
| vincentfrancoise | we were discussing the eventuality of creating an new repo (openstack or not) that would centralise non-essential plugins that we would support on a best effort basis | 15:29 |
| tkaczynski | yeah, maybe that would be a better place | 15:30 |
| vincentfrancoise | at least that way we would be able to provide all the plugins we want without having to put too much in the "core" | 15:32 |
| vincentfrancoise | but at the time we didn't do it because the effort that represents to maintain plugins in a separate repo was not yet worth it | 15:33 |
