AwsTileRequest.get_data() doesn't work

Hi there,
I'm jsut getting into your python tool but I am not able to reproduce your Aws example.

Hi shmulik90,

you are right, the example doesn't work anymore and we found out the reason is the new version of opencv-python Python package used for reading JPEG 2000 images from file.

It was updated 2 days ago from 3.4.0.14 to 3.4.1.15 and now supports OpenCV library 3.4.1. The new version can only read 8-bit or 16-bit JPEG 2000 files and in case of Sentinel-2 tiles, which are 15-bit, just returns None.
(This is actually somewhat improvement from the previous version which read 15-bit incorrectly and we had to write additional code in sentinelhub to correct the values.)

So the solution would be that you revert your version of opencv-python library to 3.4.0.14 with:

pip uninstall opencv-python
pip install opencv-python==3.4.0.14

And we will update sentinelhub setup with dependency to this older version of python-opencv. Until OpenCV is improved again or we find alternative library for reading 15-bit jp2 files this solution will have to do.

We have just released sentinelhub version 2.0.2 with dependency opencv-python==3.4.0.14. With this everything should work again.

Thanks for reporting the problem.
