Does simply `import cfgrib` work for you? I suspect it doesn't, which would explain the issue. It's unfortunate that the error is rewritten to ""unknown engine"", but I'm not sure how we would detect that it's a dependency that fails.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1732510720

We somewhat recently dropped the builtin `cfgrib` engine in favor of the one provided by the `cfgrib` package (and that is also the reason why the example in the docs fails: `cfgrib` is not installed into the docs environment anymore, which is definitely an oversight).

Which version of `cfgrib` do you have? For reference, in the environment built with the command above I have `cfgrib=0.9.10.3`","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1732510720
