hey yall, observing that the modal worker image build adds a

modal_requirements.txt

that downgrades fastapi + pydantic + prefect dependencies. If i try to override this default, it has starlette==0.32 hardcoded, which prevents installing any other versions.

hi @Pratham - can you show how you're observing that? and also your setup if possible

https://gist.github.com/PrathamSoni/9f6ef61b146bb44793f69c1c82178abf logs here. so you'll notice there's a

modal_requirements.txt

step which is after our image is unpacked which downgrades pydantic via fastapi. then there's a

python -m pip install prefect starlette==0.32.0.post1

which then forces prefect 2 via pydantic

hi @Pratham if you need dedicated time, i'll point you here to book a demo. otherwise feel free to ask one off questions here in #CL09KU1K7

Thanks Nate, yeah if we could get clarity on this that would be great then. Think we do have some call scheduled for later today but will report back after that

Hi @Pratham here are some diagrams from our call:

🔥 thanks

Hi @Nate / @Taylor Curran — I’m running into the same issue re: the

python -m pip install prefect starlette==0.32.0.post1

preventing running prefect 3.0 with a custom image on modal. Did you get to the bottom of this? I can’t tell from the context in this thread if there’s a workaround. Thanks!!!

hey @Michael Savarese we gave up on it. think azure/aws are better supported on their end and should be easier to set up

Ahh, too bad. Thanks for letting me know. I set up AWS ECS in the meantime as a workaround but modal is a lot less overhead (when it works). What’s odd is that when using the default prefect image, modal pools seem to work just fine with prefect 3.0.

Hey @Michael Savarese, yeah we moved to ACI since it was better supported. Thanks for the shout
