hii, does anybody now how to declare "from datetime import datetime" as python dependency in docker storage?

Copy code

flow.storage = Docker(registry_url="<http://gcr.io/keller-steering-enabling/flows|gcr.io/keller-steering-enabling/flows>", image_name="billwerk-contracts",
                      python_dependencies=["pandas", "oauthlib ", "requests", "requests_oauthlib", "datetime", "oauth2client", "snowflake", "datetime"], secrets=["GCP_CREDENTIALS"])

above doesn't properly work thanks!

datetime

is inbuilt, you dont need to declare them in your dependencies because they are part of the language itself. Same with
requests
, remove them from the dependencies completely

I suspect you are confusing the package datetime with the module datetime. Either of these would work:

Copy code

import datetime
now = datetime.datetime.today()

Copy code

from datetime import datetime
now = datetime.today()

mmmh but in a docker storage?

It would work the same - the issue here isnt to do with docker storage, the code either has incorrect imports or you have shadowed the datetime name in some way. Perhaps a good way is to change the code so that you dont use the word datetime outside of the imports

Copy code

from datetime import datetime as dt
now = dt.today()

Ah yes, my apologies, I was thinking of urllib.request, I need my morning coffee
