oh are the docs out of date?
sorry
can you do an 
ls -lR
and what’s the pyflyte run command?

is the file empty?

Eduardo Matus

01/09/2023, 7:55 PM
example.py? nope
y

Yee

01/09/2023, 7:55 PM
can you 
cat example.py
i might be parsing ls incorrectly, but i think that’s saying it’s 0 size.

no idea why was 0 bytes.. had to save it again and now I get this: status = StatusCode.UNAVAILABLE details = "failed to connect to all addresses; last error: UNKNOWN: ipv4127.0.0.130081: Failed to connect to remote host: Connection refused" debug_error_string = "UNKNOWN:failed to connect to all addresses; last error: UNKNOWN: ipv4127.0.0.130081: Failed to connect to remote host: Connection refused {created_time:"2023-01-09T165714.320531-03:00", grpc_status:14}"

😞
sorry… need to amend flytekit.
could you please add this in the meantime
one sec
could you 
cat ~/.flyte/config-sandbox.yaml
?
see if that file is there?
e

Eduardo Matus

01/09/2023, 8:03 PM
Yes.. is there
cat ~/.flyte/config-sandbox.yaml admin: # For GRPC endpoints you might want to use dns:///flyte.myexample.com endpoint: localhost:30081 authType: Pkce insecure: true console: endpoint: http://localhost:30081 logger: show-source: true level: 0%
pyflyte is trying to connect to port 30081. just updated the config file to use that port but need to restart the service
y

Yee

01/09/2023, 8:05 PM
yeah but you shouldn’t have to…
what was the output when you did flytectl demo start?
would you still happen to have that?

👨‍💻 Flyte is ready! Flyte UI is available at http://localhost:30080/console 🚀 🚀 🎉 ❇️ Run the following command to export sandbox environment variables for accessing flytectl export FLYTECTL_CONFIG=/Users/ematus/.flyte/config-sandbox.yaml 🐋 Flyte sandbox ships with a Docker registry. Tag and push custom workflow images to localhost:30000 📂 The Minio API is hosted on localhost:30002. Use http://localhost:30080/minio/login for Minio console
I can access to the UI
y

Yee

01/09/2023, 8:14 PM
oh then yeah can you change the config file to 30080
and then 
pyflyte -c ~/.flyte/config-sandbox run ...
while i track this down
e

Eduardo Matus

01/09/2023, 8:17 PM
was able to run passing the config file.. after the run, I should see something in the flyte UI?
y

Yee

01/09/2023, 8:18 PM
yup
we will fix this
should not be required, it should just work
wait you didn’t run that export right?
e

Eduardo Matus

01/09/2023, 8:22 PM
not seeing any updates in the interface
I did run the export
y

Yee

01/09/2023, 8:23 PM

e

Eduardo Matus

01/09/2023, 8:27 PM

this is with the export and the config file set to 30080?
could you 
echo $FLYTECTL_CONFIG
to confirm?
i want to try to get it to work without specifying the 
-c
and without the export… but with the export, it should definitely work
i have a new environment up. am not able to repro.

Hi @Eduardo Matus I am facing the same error you faced. I am able to run pyflyte locally but remote option fails. Running this command 
pyflyte -c ~/.flyte/config-sandbox.yaml run --remote example.py wf --n 500 --mean 42 --sigma 2
gives the same error as yours.
If you have got it working, please do share what i am missing here. Thank you so much
Hi @Eduardo Matus, once i changed the admin's endpoint in config-sandbox.yaml I was able to submit workflows to my local cluster. Here is my updated config.
Copy code
cat ~/.flyte/config-sandbox.yaml 
admin:
  # For GRPC endpoints you might want to use dns:///flyte.myexample.com
  endpoint: localhost:30081
  authType: Pkce
  insecure: true
console:
  endpoint: <http://localhost:30080>
logger:
  show-source: true
  level: 0

Hi, I’m running into the same error here and adjusting the config doesn’t seem to have any effect

btw, @Joe Hartshorn managed to get it working by running 
export FLYTE_PLATFORM_URL=localhost:30080
