@ancient-wolf-19325 i'm trying to use the new
WebhookTask
feature. i have flytekit 1.16.3 installed and my IDE recognizes the import
from flytekit.extras.webhook import WebhookTask
. however, when i run the workflow with
--remote
i see this error:
Caused by: ModuleNotFoundError: No module named 'flytekit.extras.webhook'
a
It seems likely that your issue is due to the container image used for remote execution not having the
flytekit
version (1.16.3) that includes the
flytekit.extras.webhook
module. While your local environment recognizes the import, the remote Flyte execution environment may be using an older image or one without the necessary extras installed, leading to the
ModuleNotFoundError
for
flytekit.extras.webhook
(source). To resolve this, ensure that the Docker image specified for your workflow execution includes
flytekit>=1.16.3
and any required plugins. You can do this by building a custom image with the correct dependencies and specifying it via the
--image
flag when running or registering your workflow (example). Would you like more detail on how to build and use a custom image for Flyte workflows? Sources: - https://github.com/flyteorg/flyte/issues/3687 - example πŸ‘ 0 button πŸ‘Ž 0 button πŸ’‘ Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 i'm using the latest flytekit image published by Flyte:
@task(container_image="<http://ghcr.io/flyteorg/flytekit:py3.12-latest|ghcr.io/flyteorg/flytekit:py3.12-latest>")
. after a small configuration change, i'm now seeing this related exception:

The error occurs because the
WebhookTask
feature requires the
httpx
library, which is not included in the default Flytekit image (
ghcr.io/flyteorg/flytekit:py3.12-latest
). The image contains Flytekit and its core dependencies, but optional dependencies like
httpx
(needed for
flytekit.extras.webhook
) must be installed separately (source). To fix this, you need to build a custom Docker image based on
ghcr.io/flyteorg/flytekit:py3.12-latest
and add
httpx
(e.g., via
pip install httpx
). Then, use this custom image for your task. Would you like detailed steps or a sample Dockerfile for this process?

@ancient-wolf-19325 what's the syntax to add an annotation to a single task that would include the
httpx
dependency in the default container?
a
It seems likely that you cannot add a Python dependency like
httpx
to a task via an annotation alone when using the default Flytekit container image. Instead, Flyte recommends specifying dependencies using an
ImageSpec
in your code, which builds a new image with the required packages (source). There is no supported annotation or decorator parameter that injects Python packages into the default image at runtime. Here’s an example using `ImageSpec`:
Copy code
from flytekit import ImageSpec, task

custom_image = ImageSpec(
    registry="ghcr.io/flyteorg",
    packages=["httpx"]
)

@task(container_image=custom_image)
def my_task():
    import httpx
    # your code here

ImageSpec
or build custom images?
