@Marvin when I try to run my own created block fromfrom __prefect_loader__ import "own_block" it returns a ModuleNotFoundError: No module named '__prefect_loader__' error. What am I doing incorrectly?

It seems like you might be attempting to use the module incorrectly. Instead of

__prefect_loader__

, you should use Prefect's functions for managing blocks or deploying flows. Here are some insights and alternatives: 1. Issue with

__prefect_loader__

: - The error

ModuleNotFoundError: No module named '__prefect_loader__'

typically occurs when there's a misuse or a bug in importing modules or deploying flows. - See this GitHub issue for reference. 2. Correct Way to Register and Use Blocks: - You can register a block using Python code instead of relying on an internal loader module. Here’s a snippet from the Prefect Documentation:

python
     from prefect.blocks.core import Block

     class MyCustomBlock(Block):
         @staticmethod
         def say_hello():
             print("Hello from MyCustomBlock!")

     # Register the block to make it available in Prefect
     MyCustomBlock.register_type()

3. Using Deployment for Flows: - When deploying a flow, employ the

Deployment

class from Prefect. Here’s an updated pattern from the latest guidelines:

python
     from prefect import flow
     from prefect.deployments import Deployment

     @flow
     def hello_world():
         print("Hello, world!")

     deployment = Deployment.build_from_flow(
         flow=hello_world,
         name="hello-world-deployment",
     )
     deployment.apply()

- For more details, you can check the Prefect Deployments Tutorial. By following these best practices, you can avoid the

ModuleNotFoundError

and correctly implement Prefect’s capabilities for blocks and deployments. If you need more specific assistance, please provide more context or examples of your current approach.
