Installing the conda environment

If you have not yet installed conda on your machine, you should start with this step : conda installation.

A yml file is included to automatically create a conda virtual environnment with the correct libraries and dependencies installed. To install it run this command in the root directory of the modspa_pixel project:

(base) /modspa_pixel$ conda env create -f modspa_pixel_env.yml

To activate the environment:

(base) /modspa_pixel$ conda activate modspa_pixel

(modspa_pixel) /modspa_pixel$

That’s all for this step!

Warning

The OTB package might not be properly installed with conda, to check its installation run the following command:

(modspa_pixel) /modspa_pixel$ otbcli_ReadImageInfo    # some random otb application
