Build Notes

This is some basic instructions on how I setup my Python/Scipy/NumPy/Pandas/etc stack. This is really just for me and probably won't help anyone else. The only thing I am missing is a description of how to install pip.

Basic Setup

1. Download and install Continuum Analytics's Anaconda

2. In the terminal, run:

   conda create -n py3k python=3 anaconda source activate py3k

Activate py3k

source activate py3k

Running iPython notebook with Anaconda's Python 3 Environment

1. Open the terminal

2. Run:

export PATH=/Users/chrisralbon/anaconda/envs/py3k/bin:$PATH ipython notebook

How to install a module, in this case pandas

export PATH=/Users/chrisralbon/anaconda/envs/py3k/bin:$PATH pip install pandas

How to install a module via condas, in this case pandas

conda install -n py3k pip

Note that py3k is the name of the acaconda environment we installed in the top of this document

To make Python3 work with sublimetext3

1. Go to tools/build system/build new system, call it "Python3"

2. Paste in this (if you have Anaconda installed)

   { "cmd": ["/Users/chrisralbon/anaconda/envs/py3k/bin/python3", "-u", "$file"], "file_regex": "^[ ]File "(...?)", line ([0-9]*)", "selector": "source.python", "env": {"LANG": "en_US.UTF-8"} }

To make Anaconda's Python2 work with sublimetext3

1. Go to tools/build system/build new system, call it "Python2"

2. Paste in this (if you have Anaconda installed)

   { "cmd": ["/Users/chrisralbon/anaconda/bin/python", "-u", "$file"], "file_regex": "^[ ]File "(...?)", line ([0-9]*)", "selector": "source.python", "env": {"LANG": "en_US.UTF-8"} }

How to install a module from github.

In this case, this module: https://github.com/wrobstory/climatic.git

export PATH=/Users/chrisralbon/anaconda/envs/py3k/bin:$PATH pip install -e git+https://github.com/wrobstory/climatic.git#egg=climatic

Upgrade a module, in this case pip

conda update pip -p /Users/chrisralbon/anaconda/envs/py3k

Setup SublimeREPL to connect to Anaconda's Python3

In your Packages/User folder, create SublimeREPL/config/Python/Main.sublime-menu with the following contents:

[
    {
        "id": "tools",
        "children":
        [{
            "caption": "SublimeREPL",
            "mnemonic": "r",
            "id": "SublimeREPL",
            "children":
            [
                {
                    "caption": "Python",
                    "id": "Python",

                    "children":[
                        {
                            "command": "repl_open",
                            "caption": "Python - Anaconda",
                            "id": "repl_python",
                            "mnemonic": "p",
                            "args": {
                                "type": "subprocess",
                                "encoding": "utf8",
                                "cmd": ["/Users/chrisralbon/anaconda/envs/py3k/bin/python3", "-i", "-u"],
                                "cwd": "$file_path",
                                "syntax": "Packages/Python/Python.tmLanguage",
                                "external_id": "python",
                                "extend_env": {"PYTHONIOENCODING": "utf-8"}
                            }
                        },
                        {
                            "command": "repl_open",
                            "caption": "IPython - Anaconda",
                            "id": "repl_python_ipython",
                            "mnemonic": "p",
                            "args": {
                                "type": "subprocess",
                                "encoding": "utf8",
                                "autocomplete_server": true,
                                "cmd": ["/Users/chrisralbon/anaconda/envs/py3k/bin/python3", "-u", "${packages}/SublimeREPL/config/Python/ipy_repl.py"],
                                "cwd": "$file_path",
                                "syntax": "Packages/Python/Python.tmLanguage",
                                "external_id": "python",
                                "extend_env": {
                                    "PYTHONIOENCODING": "utf-8",
                                    "SUBLIMEREPL_EDITOR": "$editor"
                                }
                            }
                        }
                    ]
                }
            ]
        }]
    }
]

Save the file, and you should now have Tools -> SublimeREPL -> Python -> Python - Anaconda and IPython - Anaconda menu options to start REPLs with the Anaconda interpreter.

To launch ipython notebook (with anaconda's python 3) in chrome
