Which version of gdal did you install?

See below, you are probably not using the correct syntax.

This is not correct,  trmm.nc does not have soil_moisture_x variable

And you don't need to add NETCDF: to the file syntax, unless you are
using a subdataset - the full path will be given by `gdalinfo file.nc`

you should just open it like this

dsin = gdal.Open('trmm.nc')
