See my previous comments 🙂

Did you comment out your azure.stroage configuration in trains.conf ?

It says container name is optional in azure.storage , if I don't provide the container name, and remove it from the end of default_uri , would that work?

SmarmyDolphin68 I have an idea - can you check if the AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_KEY environment variables are set in your environment? Trains will use these as overrides, maybe that's the issue

Should we also provide credentials for the Storage Account on the Web UI under 'Profile' section?

I'll find out - haven't tried that in a long time 🙂

This is very strange, I traced the code and the only thing that might cause this issue is if the configured account name (in sdk.azure.storage.contrainers...account_name is not identical to the the first host name part in the output_uri you're using (i.e. immediately following azure:// ).

Sure, it was fun 😄

Should we also provide credentials for the Storage Account on the Web UI under 'Profile' section?

See https://allegro.ai/docs/webapp/webapp_profile/#cloud-access-credentials
To get the SAS access token, go to the Azure Portal ( https://portal.azure.com ) >> storage accounts >> allegro >> shared access token >> set an expiration date in the far future >> create token >> copy "SAS token"

Ahh okay, commented out the whole thing and got the same error as earlier ( Could not get access credentials )

Should we also provide credentials for the Storage Account on the Web UI under 'Profile' section?

Can I see the whole error again?

😄

Let's try to circumvent the issue by using the environment variables. Try setting AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_KEY (with your account name and account key, respectively) and commenting out the configuration in trains.conf

Since Trains does not yet support the latest version of azure.storage.blob

Sure 😄

Thanks a lot SuccessfulKoala55 🙂

2020-12-03 13:31:27,296 - trains.storage - ERROR - Azure blob storage driver not found. Please install driver using "pip install 'azure.storage.blob>=2.0.1'"

Also, I think this message is not entirely correct and was fixed in the upcoming version - please install
pip install 'azure.storage.blob==2.0.1

Note you can't leave an empty {...} entry there... It can be an empty list but not a list with an empty dictionary...

Ooops.... we missed the most obvious thing...

No, those env variables aren't set.

But ValueError: Could not get access credentials for ' azure://trains.blob.core.windows.net/trains ' , check configuration file ~/trains.conf
basically means Trains failed to find the configured credentials in your trains.conf for azure://trains.blob.core.windows.net/trains (or whatever it was before you changed that for security reasons 🙂 )

You can try removing the env vars and using trains.conf again

This is what I get with the ' https:// ' , this is atleast getting a response from Azure

Oh it worked! I did the pip install multiple times earlier, but to no avail. I think it's because of the env variables? Let me try to unset those and provide it within the trains.conf

I did that, and it works flawlessly. I swear I installed the Azure blob storage package multiple times, anyway thanks a lot again for the detailed debugging O:)

I'm not sure regarding the env vars - it should have worked with the config file too (that's how it works on my machine)
