Error: type object 'UDF' has no attribute 'from_file'

openEO Platform

Hey

We’ve tried to run this jupyternotebook where we have the UDF but when we reach the cell process = openeo.UDF.from_file("UDF/hillshade_UDF.py", runtime="Python") it complains about: **AttributeError** : type object 'UDF' has no attribute 'from_file'.

We followed an example (udf = openeo.UDF.from_file("udf-code.py")) from here: User-Defined Functions (UDF) explained — openEO Python Client 0.15.0a1 documentation but it does not work in our case.

Hi Andrea, could you check if you are using the latest version of the openeo python client?

You could check via:

import openeo
openeo.__version__

The latest version is 0.14.1. To update it via pip use

pip install openeo --upgrade

Thanks Michele, I have upgraded to ‘0.14.1’ version but I cannot connect to the openeo backend connection = openeo.connect("openeo.cloud").authenticate_oidc().

The previous version does not provide this problem.

Did you try to specify the identity provider? For me this works fine:

connection = openeo.connect("openeo.cloud").authenticate_oidc("egi")

I did it.

Could you try to delete the old authentication token and authenticate again?

To find the path you can use in a command line

openeo-auth paths

or in a jupyter cell:

!openeo-auth paths

and then remove the file using:

rm REFRESH_TOKEN_PATH

here is the corresponding documentation:
https://open-eo.github.io/openeo-python-client/auth.html#auth-config-files-and-openeo-auth-helper-tool

Thanks it works now!

FYI: If you are working in a notebook context, you can easily remove the refresh token file with this python snippet too:

from openeo.rest.auth.config import RefreshTokenStore
RefreshTokenStore().remove()
