conda setup

This page is designed to give some basics on managing the python environment with conda. Installation details can be found at anaconda on the dev setup page.

• Anaconda documentation
• Anaconda cheat sheet

Install locations

• default install location on windows @ C:\Users\lan___id\AppData\Local\Continuum\Anaconda3 (hidden on epa machines)
• default install location on mac @ ~/anaconda/bin/python

conda management

general conda info and configuration

# epa win10 should use anaconda prompt, not bash, for pycharm compatibility
conda --version
conda info
conda info --envs
conda list
python -V
# conda channels are controlled in the .condarc file

create conda environment for python

# epa win10 should use anaconda prompt, not bash, for pycharm compatibility
# anaconda prompt is windows prompt with stuff prepended to path
conda info --envs
conda update -n base conda # update conda itself
conda update -n root conda # update conda itself on win10
conda update python #update subversion
conda create -n py37 python=3.7 anaconda
conda activate py37
pip install --upgrade pip # for when using the shell script

install all qed dependencies into conda env

# windows machines must have c++ build tools installed, macs xcode, linux dev tools:
# http://landinghub.visualstudio.com/visual-cpp-build-tools
# with py36 activated
# navigate to a requirements_qed directory in qed_*, 
# then run our bash script that conda or pip installs all our dependencies
# linux/mac
bash ./install_conda_packages.sh
# windows from virtual env on anaconda prompt, may need to have git-scm installed
# Need to install unix extension for command prompt when installing git-scm in order
# to run bash script 
install_conda_packages.sh 
# check to see if gdal was installed ok
gdalinfo --version

install gdal and gdal dependencies (fiona) to env if they fail on epa windows

# download relevant wheel files from https://www.lfd.uci.edu/~gohlke/pythonlibs/
# to wherever you want to pip install them from, currently: 
# https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
pip install GDAL-2.2.3-cp36-cp36m-win_amd64.whl
# https://www.lfd.uci.edu/~gohlke/pythonlibs/#fiona
pip install Fiona‑1.7.11.post1‑cp36‑cp36m‑win_amd64.whl
