Question

Hi everyone looking for any tips pointers on where I m going wrong I m a couple days new to Prefect used Airflow in the past and I m trying to just setup a hello world type thing Using Prefect Core I was able to get running via CLI and also got the scheduling working My problem comes when I m trying to visualize and register a flow in the UI The UI is up and running everything is green I ran `prefect backend server prefect server start and prefect agent start` in that order but no flow in the UI ```import prefect from prefect import task Flow task def hello task logger = prefect context get logger <http logger info|logger info> Hello Cloud flow = Flow hello flow tasks= hello task flow run flow register ```

Hi < Jason Carter> Welcome smile Can you confirm that your `prefect backend` is properly set in your `config toml` Are you receiving an error message when trying to run the above script

Jason Carter · Answer

Hi < Dylan> I ve never touched the file downloaded via conda and used `prefect backend server` so I assume it s set correctly but I can reach for the config And no I m not receiving any errors the script runs as expected `python first flow py`

Jason Carter · Answer

`backend = cloud ` line 7 of my config file in a conda env

Dylan · Answer

< Jason Carter> try creating a user configuration file as outlined here That s the file that the `prefect backend server` command expects to update

Dylan · Answer

Once that s done you should expect registration to work as advertised thumbsup

Jason Carter · Answer

Thanks < Dylan> i ll test that out Should I have to change that manually or should `prefect backend server` been expected to work If manually then why the backend server call

Dylan · Answer

`prefect backend server` expects to change your user configuration file but it doesn t create one for you if it s not present I think

Dylan · Answer

Once the `$HOME prefect config toml` exists `prefect backend server` should update it appropriately and you ll be all set thumbsup

Jason Carter · Answer

so I think that s the problem I don t have a `config toml` in that location but I do have a `backend toml` file

Jason Carter · Answer

with only one line `backend = server `

Interesting

Dylan · Answer

Can you run `prefect config` and `prefect version` for me please

Matt Allen · Answer

gt The UI is up and running everything is green I ran `prefect backend server prefect server start and prefect agent start` in that order but no flow in the UI Just checking once you did all this did you also run `python my flow file py` as well That s a step that isn t necessary in airflow but is necessary in prefect

Jason Carter · Answer

Hi < Dylan> < Matt Allen> thanks for you questions and suggestions It s now working and I think there were a few issues on my first install but also the last step by Matt running `python file name py` brought everything together Seems like a manual step for production CI CD process but I m sure I just haven t gotten to those docs yet

If you re wondering what I did to fix things I basically started over from scratch ```1 Updated Conda 2 Created condo env on python3 latest 3 Had issues chat on Slack starting over 4 Remove all previous versions globally and in the env plus delete left over files 5 Env installed prefect c condo forge prefect 6 Prefect config gives cloud as backend 7 Prefect config ~ prefect but no actual folder the only config toml on machine is in condo env 8 Prefect version 0 12 5 9 Prefect backend server 10 Prefect config now gives server as backend 11 Added flow run and executed from cli worked 12 Commented out flow run and added flow register 13 Refreshed prefect UI nothing in flow shows up 14 Start docker agent prefect agent start docker 15 Nothing showing up in Prefect UI 16 Ran $python first flow py flow is now showing up in UI```
