03/22/2023, 5:27 PMIt sounds like there's an issue with the import, does importing your
service.pys
Soonbeom Choi
03/22/2023, 5:29 PMDo you mean importing service.py from another file?
s
sauyon
03/22/2023, 5:30 PMYeah, or just running import from a python interpreter.
s
Soonbeom Choi
03/22/2023, 5:31 PMYeah importing service.py to another file works but importing other local files accompanied with init.py doesn't work
s
sauyon
03/22/2023, 5:31 PMFrom python, or from BentoML?
s
Soonbeom Choi
03/22/2023, 5:31 PMI mean from python
Soonbeom Choi
03/22/2023, 5:32 PMActually there're no errors when running bentoml serve it just hangs infinitly
s
sauyon
03/22/2023, 5:33 PMWell, it has to work in Python before it works with BentoML. Sometimes the error isn't surfaced properly by BentoML because the startup hook for Starlette consumed the error silently.

Soonbeom Choi
03/22/2023, 5:34 PMRunning python service.py seems no problem
Soonbeom Choi
03/22/2023, 5:35 PM"Init: Language setting - universal: true' in the image is just single line print() in my service.py but it keeps printing and bentoml doesn't startup
Soonbeom Choi
03/22/2023, 5:41 PMFor example, I have 'util' folder as below and import util or from util import a makes this problem. When I refactor the identical code without init.py solves the problem and bentoml serves well but I don't think it is the ideal solution
Copy code
util
- __init__.py
- a.py
- b.pys
sauyon
03/22/2023, 5:44 PMDoes `PYTHONPATH=. python`then
import utils
Soonbeom Choi
03/22/2023, 5:47 PMimporting itself works i can access functions, classes, variables in util but just bentoml doesn't start to serve
s
sauyon
03/22/2023, 5:48 PMOk, I think I misunderstood what you meant earlier. Can you run with --debug and share the output?
s
Soonbeom Choi
03/22/2023, 5:51 PMI'm not sure if screenshot is ok to you.
the debug log also prints infinitly
Soonbeom Choi
03/22/2023, 5:52 PMOne thing I found was 'No default method found for Runner' is not related with this issue
s
sauyon
03/22/2023, 10:01 PMAh, yeah. I'm trying to reproduce now, though if you could send me a small example that breaks that would be much appreciated.
sauyon
03/22/2023, 10:07 PMHm, yeah, tried making a minimal example with an
__init__.pys
Soonbeom Choi
03/23/2023, 3:52 AMI'm sorry I tested my code more deeply and find out that importing module itself wasn't the problem. importing wandb causes the infinite loop and my modules somehow imports wandb or part of it.
Now I can solve the problem just by removing import wandb but may I ask you if you have any guess why importing wandb causes infinite loop.
s
sauyon
03/23/2023, 3:57 AMHm, I'll try that out, thanks for the update! We definitely need to figure out why the server doesn't print any errors at all...
s
Soonbeom Choi
03/23/2023, 4:02 AMThanks for your support too! As for now I don't have to use wandb and bentoml at the same time so I can just ignore import wandb. But I will be happy to figure out the reason. Thanks!
