Hi Sean!

After updating rasterio I get the following error:

In [1]: from rasterio import open

 

In [2]: open('tests/data/raster/rgb.jp2')

---------------------------------------------------------------------------

CPLE_OpenFailedError                      Traceback (most recent call last)

rasterio/_base.pyx in rasterio._base.DatasetBase.__init__()

 

rasterio/_shim.pyx in rasterio._shim.open_dataset()

 

rasterio/_err.pyx in rasterio._err.exc_wrap_pointer()

 

CPLE_OpenFailedError: 'tests/data/raster/rgb.jp2' not recognized as a supported file format.

 

During handling of the above exception, another exception occurred:

All works without any problems with rasterio 1.0.2:

In [1]: from rasterio import open

 

In [2]: open('tests/data/raster/rgb.jp2')

Out[2]: <open DatasetReader name='tests/data/raster/rgb.jp2' mode='r'>
