`tree_cover_density_2018_romania.tif' not recognized as a supported file format.

Hey there, I am attempting to test out nrt but it seems the example tif (tree_cover_density_2018_romania) is corrupted in some way.

When following the example workflow rasterio throws an error :

# load example mask
mask = (data.romania_forest_cover_percentage() > 20).astype('int')

RasterioIOError: '/nrt/nrt/data/tree_cover_density_2018_romania.tif' not recognized as a supported file format.

Doing a gdalinfo produces the same not recognized as supported file format error, and likewise it cannot be opened in QGIS.

How did you install the package? From pypi or from a clone of this repository?

[jdilger]

I installed the dependencies with conda (rasterio, xarray, dask, scipy, netCDF4, affine, numba), pypi for the package using python 3.9. I think it could be a me issue though, even if I omit the mask, I run into an error saying xarray is missing the correct IO backends for 'netcdf4' and 'scipy'.

Sorry, just seeing now that you responded to the issue. A simple pip install nrt should normally resolve all dependencies. The reason I was asking about how it was installed is because these files (mask, example data cube, etc) are under git lfs which by default is not installed on most systems. Cloning and installing with pip install . or installing with pip install git+https://... when git lfs is not installed would very likely lead to the error you reported.

Ah thank you very much. The issue was certainly git lfs I was not familiar with using that. After installing lfs and pulling the data it appears to be working.
