can't open jp2 (from sentinel) with python rasterio,gdal

Question

I am trying to open the jp2 rasters products in python as raster, without success when we use the "raterio" and "gdal" packages.
I get this errors:

RasterioIOError: 'b4.jp2' not recognized as a supported file format.
RuntimeError: `b4.jp2' not recognized as a supported file format.

I do manage to open them as a regular matrix with "glymur" package but then i lose the geo data.

If someone know other pachage to open jp2 as raster i would be happy to know!

I tried to follow this answer: Python3.7 rasterio library cant open jp2 installed fiona by conda or: https://gis.stackexchange.com/questions/250833/gdal-missing-jp2-driver-files-how-to-install-them/250837#250837 and tried to install :conda create -n mynewenv -c conda-forge gdal rasterio but i still get the same errors.

b4 = rasterio.open('b4.jp2')
b4 = rasterio.open('b4.jp2', driver= 'JP2OpenJPEG')

Answer 1

This is quite similar to what you have tried, but this procedure just worked for me. Note: I am specifying I want a python 3.7 environment. From the anaconda prompt:

conda create --name testing python=3.7
conda activate testing
conda install -c conda-forge gdal rasterio

Verified correct install:

>>> import rasterio
>>> import gdal
>>> gdal.VersionInfo()
'3000100'
>>> rasterio.gdal_version()
'3.0.1'

And check to make sure .jp2 driver is supported. From the anaconda prompt:

rio env --formats

which returns a long list with the entries:

JML: OpenJUMP JML
JP2OpenJPEG: JPEG-2000 driver based on OpenJPEG library
JPEG: JPEG JFIF

From spyder, you can check to see where spyder is running from using

import sys
print(sys.executable)

You should see something like:

C:\Anaconda2\envs\testing\pythonw.exe

The installation directory C:\Anaconda2\ will depend on where you have anaconda installed to, But the latter part envs\testing\pythonw.exe should be the same.
