Error “KeyError: '.zmetadata'” is reported when running “xmitgcm llcreader demo”

[Hana0002]

Dear xmitgcm community and any seniors who might be able to help me~

I am writing to seek assistance with a technical issue I have encountered while running “xmitgcm llcreader demo” with xmitgcm of python and jupyter of vscode.

I downloaded and used the demo you provided, and solved some problems with the package version. But I encountered the error "KeyError: '.zmetadata'". I didn't find a solution on the web. May I ask why this problem occurs? Is it because I'm running in the wrong environment?

I would greatly appreciate any guidance or suggestions you can provide to help me resolve this issue. Here's a screenshot of the errors I got from running the two demos separately.

Thank you in advance for your time and support. A sincere but green graduate student ～>_<～

I can confirm that I also get this error message when I try to use the ECCO data portal. It seems to me that this is because the mask data has either moved or disappeared from google cloud. We may be able to host this data elsewhere if I can find a copy. I will talk to @rabernat to see if this can be sorted out.

There mask data have not disappeared from google cloud. https://console.cloud.google.com/storage/browser/pangeo-ecco

Ahh ok - my bad. Updating the environment seems to resolve this error.

I met the same error. What should I upgrade to resolve this error, could you please express more specificly? @cspencerjones

I suggest reinstalling your environment completely, since that is what I did to resolve the error.
