Zhu Lei commented on SINGA-399:
-------------------------------
Hi Ngin Yun Chuan, thanks for your reply,
1). I think I am not facing the first scenario, as the only changes I made to
predictor.py to check Rafiki can run newly built image is only to let it return
\{'prediction': 'test'} as shown in attached image 'rafiki-5.PNG'.
2). for the second scenario, I rebuilt the new images, where the only change is
that the predict() function in predictor.py returns \{'prediction': 'test'}. I
follow my previous procedure, running 'bash ./scripts/start.sh' and 'python
client-usage.py'. I got the same error as I mentioned. later, I run the
commands you suggest in
[https://nginyc.github.io/rafiki/docs/docs/user/quickstart-app-users.html]. The
predictor server correctly returns the result as shown in image 'rafiki-6.PNG'.
However, the predictor are not using the modified predictor.py. I think it
somehow in the middle replace the newly built predictor image with the docker
hub one. !rafiki-5.PNG!!rafiki-6.PNG!
> Rafiki cannot test rebuilt image

> After downloading the newest rafiki code, at commit
> 7b3b04e15c62233e515c4d82051cd5dfb799215f, with comments "Add more error
> handling to notify user of invalid train job; compact exceptions", I ran
> "bash ./scripts/build_images.sh" to build the new admin, advisor, predictor
> and worker images. I got the images shown in attached image 'rafiki-1.PNG'.
> Then I run "bash ./script/start.sh" to build the containers as shown in the
> attached image 'rafiki-2.PNG'. Finally when I ran the client-usage.py
> example. I got the error in attached image 'rafiki-3.PNG'.
> And I find very surprising that the images of admin, advisor, predictor and
> worker I built just now, become some images built weeks ago, shown in
> attached image 'rafiki-4.PNG'. Could you kindly provide me some explanations
> on why this happens? I really do not understand why this happened.
> And finally, when I run "bash ./script/stop.sh" and leave the swarm and
> repeat my previous procedure again, now there is no errors. The only thing
> difference between the two runs I think is only the images are different. So
> the current code of rafiki does not support newly build images, that is my
> speculation.
