英文:
Unable to open Netcdf variable in xarray
问题
It looks like you're trying to open a variable named 'u-vel' using xarray in Python. To access this variable, you can use square brackets like this: DS['u-vel']. This should allow you to access the 'u-vel' variable in your dataset.
英文:
I am opening a dataset using xarray with this line: DS = xr.open_dataset(dataDIR). When I use DS.variables, I see that there's a variable named 'u-vel', however, when I try to open this variable using DS.u-vel, it returns me the following:
> 'Dataset' object has no attribute 'u'
I think that the python is interpreting it as me trying to open the u variable in DS and subtract it from my local variable vel. I have tried using DS."u-vel", but it did not work either.
Does anybody know how should I open this variable using xarray?

u-vel 不是Python属性的有效名称。您应该使用getitem接口来访问数据集以访问此变量：
da = ds['u-vel']
总的来说，虽然属性样式访问很方便，但我认为最好默认使用getitem访问模式，以避免类似这种问题以及与xarray命名空间的其他部分冲突。
英文:
u-vel is not a valid name for a Python attribute. You'll want to use the getitem interface to the dataset to access this variable:
da = ds['u-vel']
In general, while the attribute style access is convenient, I think its better to default to using the getitem access pattern to avoid issues like this one as well as conflicts with other parts of the xarray namespace.
