Hi everyone,

I'm trying to create a raster from a numpy array but I get this error
"TypeError: Integer width and height are required." in
rasterio/_io.pyx in rasterio._io.DatasetWriterBase.__init__()

I'm printing width and height and I'm sure they are integers so I
cannot understand why I get that error. Does anyone have an idea what
I should check to solve this problem?

I can share my code if needed.

Thanks

Yes please share your code.

The code is here https://pastebin.com/YSAqsuN2

I have my input array, I mask it with mask_raster_with_geometry
function (it works properly) and after I need to create the tif.
It print the dimensions (line 65) as (1, 7, 4, 1)

These are the input data of create_temporary_dataset function

- input array
array([[[ nan, nan, nan, nan],
[0.51981352, 0.56658679, 0.56957087, nan],
[0.53405018, 0.5880829 , 0.52095808, nan],

Instead of `band_number = np.arange(count) + 1` on line 21, try `band_number = range(1, count + 1)`
I didn't test your code specifically, but rasterio won't read a dataset when passed the band indexes as a numpy array, but will if you pass the indexes as a list, tuple or range generator.

E.g. 
src.read(range(1, 4))

File you write to must be open in writing mode:

rasterio.open('example.tif', 'w', **profile)

this was the problem, thanks a lot. The error message brings me to
check in the wrong place.
