The binaries here are used only for development and testing purposes.
The binaries are kept as minimal as possible in size. All the rest of the dependencies will be downloaded during installation. So, it is a good idea to make use of conda's caching by designating the packages directory out of EMAN2 binary installation. For existing EMAN2/miniconda/anaconda installations follow the instructions below, for new installations follow the steps after the installation:
1. conda config --add pkgs_dirs <path-to-global-conda-cache-dir>
2. mv <current-conda-directory>/pkgs/* <path-to-global-conda-cache-dir>
Once this is done, conda will not need to re-download any packages unless updates are available, even if the binary installation is removed completely and a new installation is done from scratch.
