8. ANACONDA MINICONDA PYTHON CONDA PACKAGES PYTHON CONDA a bunch of for scientific computing and data science
10. CONDA VS PIP(+VIRTUALENV) CONDA PIP Language agnostic Python packages handles environments ! natively virtualenv installs binaries compiles from source general purpose ! envs python! envs
11. CONDA + PIP $ conda install pip $ pip install foo CONDA SKELETON PYPI $ conda skeleton pypi foo $ conda build foo/
12. WHY USE CONDA? Seen this message too many times:“Storing debug log for failure in /.pip/pip.log” Python with compiled, platform- dependent C, C++, or Fortran code Multi-language Data Science Projects
15. ANACONDA.ORG ~GITHUB FOR BINARY PACKAGES $ conda build conda.recipe/ $ conda server upload my_foo_pkg $ conda install -c chdoig my_foo_pkg
18. ANACONDA.ORG/R $ conda install -c r r-foo
