codec not available: 'imagecodecs_jpegxl'

[MosGeo]

Hello,

I am hitting the codec not available error when trying to create a zarr array with the jpeg compressers. In the example below, the jpegxl_encode works. It is just the zarr compressor that is hitting the issue.

Now, I am on Windows 64bit and I tested on both Windows 10 and Windows 11. Both are using Python 10. So it is not the issue in #74 .

Any advise would be appreciated

import numpy as np
import zarr
from imagecodecs.numcodecs import Jpegxl
from imagecodecs import jpegxl_encode

data = np.random.randint(0, 256, size=(1000,1000), dtype=np.uint8)

# This works
encoded = jpegxl_encode(data)

# This crashes
z = zarr.array(data, compressor=Jpegxl())

Did you register the codec with numcodecs/zarr like shown in the JPEG2K example:

https://github.com/cgohlke/imagecodecs/blob/57ea74b0e1d8bf78f10a74d0ee896eee36eaf65c/imagecodecs/imagecodecs.py#L464-L476

Alternatively, install the imagecodecs-numcodecs package, which defines numcodecs entry points.

No, I didn't register it 🤣 I am new at this stuff so I didn't know I had to. All good now :)
