need help installing rasterio with WebP

tgertin@...
 

I am using Ubuntu with Anaconda.

I would like to install rasterio with WebP. Help would be greatly appreciated on how to do this, especially some example commands.

Thanks,

Hi Tom,

I'm not an Anaconda user and don't know how to build packages for it. I think you'll want to find a conda channel that has rasterio packages with WebP support built in. I think that's most likely to be the conda-forge channel. If it doesn't have WebP support, I suggest requesting it at https://github.com/conda-forge/gdal-feedstock.

Bitner recently added WebP to linux GDAL Conda Forge builds https://github.com/conda-forge/gdal-feedstock/pull/346 I have no idea when that will make it into Anaconda's channel though.

Thank you for looking into this. I am running these commands using the conda-forge channel:

```
conda create --name rasterio_w_webp_test1 python=3.7
 
conda config --add channels conda-forge
 
conda install gdal libgdal
 
conda install rasterio
 
pip install rio-cogeo
```

Then I am using the rio cogeo command that uses WebP:
```
rio cogeo create -p webp input.tif output.tif
```

but I get the following error:
```
File "rasterio/shutil.pyx", line 139, in rasterio.shutil.copy
  File "rasterio/_err.pyx", line 205, in rasterio._err.exc_wrap_pointer
rasterio._err.CPLE_AppDefinedError: Cannot create TIFF file due to missing codec for WEBP.
```

so I think something didn't install correctly. I don't need to use conda, but it seems like a good option because it uses virtual environments.

The reason this doesn't work is Conda/Conda Forge uses an external libtiff build which does not have WebP support enabled. The "WEBP" GDAL driver by itself should work because that is linked differently (but that isn't a TIFF/WebP either). I have initiated an update to Conda Forge's libtiff to add WebP support, but this is likely to take a while for this build to filter back through. See https://github.com/conda-forge/libtiff-feedstock/pull/48 for more details.
