Under Construction

Setup Development Environment with Conda

  1. If you have an existing Miniconda2 installation,

    1. Remove miniconda entries from PATH.

    2. If you want to make use of your cached packages, move your pkgs/ and envs/ folders out of your current installation to another location. 

      mkdir -p <path-to-conda-cahe-directory>
# mkdir -p ~/conda-global-cache
mv <path-to-current-miniconda2-installation>/pkgs <path-to-conda-cahe-directory>
mv <path-to-current-miniconda2-installation>/envs <path-to-conda-cahe-directory>

  2. Download Miniconda3 for Linux or MacOSX.

  3. Install Miniconda3. 

    bash <Miniconda3-installer>
    • and follow the prompts.
  4. Specify package and environment directories. 
    conda config --set pkgs_dirs <path-to-conda-cahe-directory>/pkgs
# conda config --set pkgs_dirs ~/conda-global-cache/pkgs
conda config --set envs_dirs <path-to-conda-cahe-directory>/envs
# conda config --set pkgs_dirs ~/conda-global-cache/envs
  5. Configure conda.
    1. Do not update conda automatically. 
      conda config --set auto_update_conda False
    2. If you don't want conda's base environment to be activated automatically. 
      conda config --set auto_activate_base False

  6. Install conda 4.6.14. 

    conda install conda=4.6.14 -c defaults
  7. Initialize conda for shell interaction. 
    conda init bash
# See command help for supported shells
conda init --help

Use Conda Environments for Development

Do not install anything into the base environment, do not use the base environment for development, use non-base environments.

  1. Create a new environment. 
    conda create -n eman-deps-14.1 eman-deps=14.1 -c cryoem -c defaults -c conda-forge

    OR choose a simpler name for the environment, eman-env or eman. 

    conda create -n eman-env eman-deps=14.1 -c cryoem -c defaults -c conda-forge
  2. Activate the environment. 
    conda activate eman-deps-14.1
    OR 
    conda activate eman-env
  3. Checkout a branch.
  4. Update eman2 source. 
    cd <source directory>
git checkout <branch>
git pull --rebase
  5. Navigate to your build directory, build and install. 
    cd <build directory>
cmake <eman2 source directory>
make
make install
