this is really not a netcdf4-python issue. I suspect you are select a point with missing or undefined data, but you would have to ask an xarray expert (maybe [here](https://groups.google.com/g/xarray)).

What about the approach of using conda built libs? (https://github.com/ocefpaf/netcdf4-win-wheels/pull/6) If you want to enable all the features of hdf5/netcdf-c it requires a lot of dependencies to be built -...

This looks great! Thank you @ocefpaf and @ZedThree. I'd like to get this merged soon so we can get a 1.6.5 release out with 3.12 wheels. The old MacPython wheel...

1.6.5 multi-build wheels now [available](https://github.com/MacPython/netcdf4-python-wheels/releases/tag/v1.6.5rel)

> > The old MacPython wheel building repo is [broken](https://github.com/MacPython/netcdf4-python-wheels/issues/23), and it looks like the [multibuild](https://github.com/multi-build/multibuild) package it relies on is no longer actively maintained. > > Just to say...

@dopplershift the netcdf-c library included in the multi-build wheels has support for compression plugins (blosc, zstd, lzma, etc), but the plugins themselves are not bundled. Without the plugins, I'm not...

@ocefpaf what's the status of this PR? I'd like to release 1.7.0 soon, and would like to use this instead of multibuild. Having the plugins working is not necessary.

@ocefpaf I'm fine with the current approach for hdf5. Hope you enjoyed the long weekend!

unfortunately you can't use compression on variable-length string variables.

The HDF5 library does not support compression of variable length datatypes. The lib may not have returned an error code in earlier versions, but I don't think any compression was...
