For the person with the SSL cert issue - for now, you can use the following in thread:

Lab 102 instructions (also in slides): • Use a flow that grabs weather data from open-meteo • Add retries • Start a Prefect server instance • Run your flow • Inspect in the UI • Stretch: add caching

import httpx

from prefect import flow, task

from prefect.tasks import task_input_hash

from datetime import timedelta

@task(retries=2)

def fetch_weather(lat: float, lon: float):

base_url = "<https://api.open-meteo.com/v1/forecast/>"

weather = httpx.get(

base_url,

params = dict(latitude=lat, longitude=lon, hourly="temperature_2m"),

)

most_recent_temp = float(weather.json()["hourly"]["temperature_2m"][0])

print(f"Most recent temp C: {most_recent_temp} degrees")

return most_recent_temp

@task(cache_key_fn=task_input_hash, cache_expiration=timedelta(minutes=5))

def save_weather(temp: float):

with open("weather.csv", "w+") as w:

w.write(str(temp))

return "Succefully wrote temp"

@task(retries=2, retry_delay_seconds=2)

def windspeed(lat: float, lon: float):

base_url = "<https://api.open-meteo.com/v1/forecast/>"

wind = httpx.get(

base_url,

params = dict(latitude=lat, longitude=lon, hourly="temperature_2m"),

)

wind_speed = float(wind.json()["hourly"]["windspeed_10m"][0])

print(f"Current wind speed C: {wind_speed}")

return wind_speed

@flow(retries=3)

def pipeline(lat: float, lon: float):

temp = fetch_weather(lat, lon)

result = save_weather(temp)

curr_wind = windspeed(lat, lon)

print(f"Current temp C: {temp} degrees and windspeed is {curr_wind}")

if __name__ == "__main__":

fetch_weather(38.9, -77.0)

Share code for lab 102 here (thread):

Lab 103 Instructions • Use a previously made flow • Create a Cloud profile (or use an existing one) • Authenticate for the CLI • Make an email notification automation for flow run completion • Run the flow a few times from the CLI • See the event feed in the UI • Stretch: create a Slack notification automation

do we have to create a separate account for the prefect cloud profile?

Once I log into my account on Cloud, how do I sync my local flows to the Cloud?

Is there a webhoook needed for the slack channel notification part?

Hey all! Way to rock the first half! We’ll meet back here to kick off deployments at 3pm ET. 🎉

Welcome back everyone! 🚀

Use a flow from the 103 lab • Make a deployment via interactive CLI commands • Start a worker • Run a deployment from the UI • See the flow run logs in the UI • Stretch: Create a deployment that has default parameters & override the default parameters at runtime in the UI

Ronald Error

is anyone else getting this error: Flow run infrastructure exited with non-zero status code 1

Is anyone getting that it's scheudled, but 'Late?'

Morgan Error

What version introduced the ability to overwrite the pull step in the deployment section?

Thank you @Jeff Hale @Emil Christensen @Taylor Curran I learnt a lot about Prefect today

Hi folks - I have a new question since yesterday and haven't had much luck finding an answer online. I'm trying to set up my first real deployment using my company's prod instance. We have a Prefect agent work pool that I've confirmed exists per the first screenshot below (and I can see other flow runs using this work pool). Issue is that when I follow the steps to create a deployment, I'm getting a message that I "don't have any work pools that this flow can be deployed to", so I have to create a new one. Has anybody had a similar issue?

Way to rock it, all! 🎸 Reminder to please let us know what went well and what can be improved in the 3 minute feedback form: https://prefect-community.slack.com/archives/C05ML2VG26N/p1692221736973339

Hey guys, how's it going? Has anyone received their training certificate yet?
