1 | 1 | IPython requires Python 2.7 or ≥ 3.3. |
|
2 | 2 | |
|
3 | 3 | .. note:: |
|
4 | 4 | |
|
5 | 5 | If you need to use Python 2.6 or 3.2, you can find IPython 1.0 |
|
6 | 6 | `here <http://archive.ipython.org/release/>`__. |
|
7 | 7 | |
|
8 | 8 | Quickstart |
|
9 | 9 | ========== |
|
10 | 10 | |
|
11 | 11 | If you have :mod:`setuptools`, |
|
12 | 12 | the quickest way to get up and running with IPython is: |
|
13 | 13 | |
|
14 | 14 | .. code-block:: bash |
|
15 | 15 | |
|
16 | 16 | $ easy_install ipython[all] |
|
17 | 17 | |
|
18 | 18 | This will download and install IPython and its main optional dependencies: |
|
19 | 19 | |
|
20 | 20 | - jinja2, needed for the notebook |
|
21 | 21 | - sphinx, needed for nbconvert |
|
22 | 22 | - pyzmq, needed for IPython's parallel computing features, qt console and |
|
23 | 23 | notebook |
|
24 | 24 | - pygments, used by nbconvert and the Qt console for syntax highlighting |
|
25 | 25 | - tornado, needed by the web-based notebook |
|
26 | 26 | - nose, used by the test suite |
|
27 | 27 | - readline (on OS X) or pyreadline (on Windows), needed for the terminal |
|
28 | 28 | |
|
29 | 29 | To run IPython's test suite, use the :command:`iptest` command: |
|
30 | 30 | |
|
31 | 31 | .. code-block:: bash |
|
32 | 32 | |
|
33 | 33 | $ iptest |
|
34 | 34 | |
|
35 | 35 | .. note:: |
|
36 | 36 | |
|
37 | 37 | .. code-block:: bash |
|
38 | 38 | |
|
39 | 39 | $ pip install ipython[all] |
|
40 | 40 | |
|
41 | 41 | will also work in many cases, but it will ignore the binary eggs |
|
42 | 42 | of packages such as pyzmq and readline, |
|
43 | 43 | which may be required for some users on Windows or OS X. |
|
44 | 44 | |

46 | 46 | Overview |
|
47 | 47 | ======== |
|
48 | 48 | |
|
49 | 49 | This document describes in detail the steps required to install IPython, |
|
50 | 50 | and its various optional dependencies. |
|
51 | 51 | For a few quick ways to get started with package managers or full Python distributions, |
|
52 | 52 | see `the install page <http://ipython.org/install.html>`_ of the IPython website. |
|
53 | 53 | |
|
54 | 54 | IPython is organized into a number of subpackages, each of which has its own dependencies. |
|
55 | 55 | All of the subpackages come with IPython, so you don't need to download and |
|
56 | 56 | install them separately. However, to use a given subpackage, you will need to |
|
57 | 57 | install all of its dependencies. |
|
58 | 58 | |
|
59 | 59 | Please let us know if you have problems installing IPython or any of its dependencies. |
|
60 | 60 | |
|
61 | 61 | IPython and most dependencies can be installed via :command:`easy_install`, |
|
62 | 62 | provided by the :mod:`setuptools` package, or :command:`pip`. |
|
63 | 63 | In many scenarios, this is the most simplest method of installing Python packages. |
|
64 | 64 | More information about :mod:`setuptools` can be found on |
|
65 | 65 | `its PyPI page <http://pypi.python.org/pypi/setuptools>`__. |
|
66 | 66 | |
|
67 | 67 | .. note:: |
|
68 | 68 | |
|
69 | 69 | On Windows, IPython *requires* :mod:`setuptools`. We hope to |
|
70 | 70 | change this in the future, but for now on Windows, you *must* install |
|
71 | 71 | :mod:`setuptools` to use IPython. |
|
72 | 72 | |
|
73 | 73 | More general information about installing Python packages can be found in |
|
74 | 74 | `Python's documentation <http://docs.python.org>`_. |
|
75 | 75 | |
|
76 | 76 | |
|
77 | 77 | Installing IPython itself |
|
78 | 78 | ========================= |
|
79 | 79 | |
|
80 | 80 | Given a properly built Python, the basic interactive IPython shell will work |
|
81 | 81 | with no external dependencies. However, some Python distributions |
|
82 | 82 | (particularly on Windows and OS X), don't come with a working :mod:`readline` |
|
83 | 83 | module. The IPython shell will work without :mod:`readline`, but will lack |
|
84 | 84 | many features that users depend on, such as tab completion and command line |
|
85 | 85 | editing. If you install IPython with :mod:`setuptools`, (e.g. with |
|
86 | 86 | `easy_install`), then the appropriate :mod:`readline` for your platform will be |
|
87 | 87 | installed. See below for details of how to make sure you have a working |
|
88 | 88 | :mod:`readline`. |
|
89 | 89 | |
|
90 | 90 | Installation using easy_install or pip |
|
91 | 91 | -------------------------------------- |
|
92 | 92 | |
|
93 | 93 | If you have :mod:`setuptools` or :mod:`pip`, the easiest way of getting IPython is |
|
94 | 94 | to simply use :command:`easy_install` or :command:`pip`: |
|
95 | 95 | |
|
96 | 96 | .. code-block:: bash |
|
97 | 97 | |
|
98 | 98 | $ pip install ipython |
|
99 | 99 | |
|
100 | 100 | That's it. |
|
101 | 101 | |
|
102 | 102 | .. note:: |
|
103 | 103 | |
|
104 | 104 | Many prefer :command:`pip` to :command:`easy_install`, but it ignores eggs (binary Python packages). |
|
105 | 105 | This mainly affects pyzmq and readline, which are compiled packages and provide |
|
106 | 106 | binary eggs. If you use :command:`pip` to install these packages, |
|
107 | 107 | it will always compile from source, which may not succeed. |
|
108 | 108 | |
|
109 | 109 | Installation from source |
|
110 | 110 | ------------------------ |
|
111 | 111 | |
|
112 | 112 | If you don't want to use :command:`easy_install`, or don't have it installed, |
|
113 | 113 | just grab the latest stable build of IPython from `here |
|
114 | 114 | <http://ipython.org/download.html>`_. Then do the following: |
|
115 | 115 | |
|
116 | 116 | .. code-block:: bash |
|
117 | 117 | |
|
118 | 118 | $ tar -xzf ipython.tar.gz |
|
119 | 119 | $ cd ipython |
|
120 | 120 | $ python setup.py install |
|
121 | 121 | |
|
122 | 122 | If you are installing to a location (like ``/usr/local``) that requires higher |
|
123 | 123 | permissions, you may need to run the last command with :command:`sudo`. |
|
124 | 124 | |
|
125 | 125 | Windows |
|
126 | 126 | ------- |
|
127 | 127 | |
|
128 | 128 | As mentioned above, on Windows, IPython requires :mod:`setuptools`, and it also |
|
129 | 129 | requires the PyReadline library to properly support coloring and keyboard |
|
130 | 130 | management (features that the default windows console doesn't have). So on |
|
131 | 131 | Windows, the installation procedure is: |
|
132 | 132 | |
|
133 | 133 | 1. Install `setuptools <http://pypi.python.org/pypi/setuptools>`_. |
|
134 | 134 | |
|
135 | 135 | 2. Install `pyreadline <http://pypi.python.org/pypi/pyreadline>`_. You can use |
|
136 | 136 | the command ``easy_install pyreadline`` from a terminal, or the binary |
|
137 | 137 | installer appropriate for your platform from the PyPI page. |
|
138 | 138 | |
|
139 | 139 | 3. Install IPython itself, which you can download from `PyPI |
|
140 | 140 | <http://pypi.python.org/pypi/ipython>`_ or from `our site |
|
141 | 141 | <http://ipython.org/download.html>`_. Note that on Windows 7, you *must* |
|
142 | 142 | right-click and 'Run as administrator' for the Start menu shortcuts to be |
|
143 | 143 | created. |
|
144 | 144 | |
|
145 | 145 | IPython by default runs in a terminal window, but the normal terminal |
|
146 | 146 | application supplied by Microsoft Windows is very primitive. You may want to |
|
147 | 147 | download the excellent and free Console_ application instead, which is a far |
|
148 | 148 | superior tool. You can even configure Console to give you by default an |
|
149 | 149 | IPython tab, which is very convenient to create new IPython sessions directly |
|
150 | 150 | from the working terminal. |
|

154 | 154 | |
|
155 | 155 | Installing the development version |
|
156 | 156 | ---------------------------------- |
|
157 | 157 | |
|
158 | 158 | It is also possible to install the development version of IPython from our |
|
159 | 159 | `Git <http://git-scm.com/>`_ source code repository. To do this you will |
|
160 | 160 | need to have Git installed on your system. Then just do: |
|
161 | 161 | |
|
162 | 162 | .. code-block:: bash |
|
163 | 163 | |
|
164 | 164 | $ git clone --recursive https://github.com/ipython/ipython.git |
|
165 | 165 | $ cd ipython |
|
166 | 166 | $ python setup.py install |
|
167 | 167 | |
|
168 | 168 | Some users want to be able to follow the development branch as it changes. If |
|
169 | 169 | you have :mod:`setuptools` installed, this is easy. Simply replace the last |
|
170 | 170 | step by: |
|
171 | 171 | |
|
172 | 172 | .. code-block:: bash |
|
173 | 173 | |
|
174 | 174 | $ python setupegg.py develop |
|
175 | 175 | |
|
176 | 176 | This creates links in the right places and installs the command line script to |
|
177 | 177 | the appropriate places. Then, if you want to update your IPython at any time, |
|
178 | 178 | just do: |
|
179 | 179 | |
|
180 | 180 | .. code-block:: bash |
|
181 | 181 | |
|
182 | 182 | $ git pull |
|
183 | 183 | |
|
184 | 184 | |
|
185 | 185 | Basic optional dependencies |
|
186 | 186 | =========================== |
|
187 | 187 | |
|
188 | 188 | There are a number of basic optional dependencies that most users will want to |
|
189 | 189 | get. These are: |
|
190 | 190 | |
|
191 | 191 | * readline (for command line editing, tab completion, etc.) |
|
192 | 192 | * nose (to run the IPython test suite) |
|
193 | * pexpect (to use things like irunner) | |
|
194 | 193 | |
|
195 | 194 | If you are comfortable installing these things yourself, have at it, otherwise |
|
196 | 195 | read on for more details. |
|
197 | 196 | |
|
197 | IPython uses several other modules, such as pexpect_ and path.py, if they are | |
|
198 | installed on your system, but it can also use bundled versions from | |
|
199 | :mod:`IPython.external`, so there's no need to install them separately. | |
|
200 | ||
|
198 | 201 | readline |
|
199 | 202 | -------- |
|
200 | 203 | |
|
201 | 204 | As indicated above, on Windows, to get full functionality in the console |
|
202 | 205 | version of IPython, PyReadline is needed. |
|
203 | 206 | PyReadline is a separate, Windows only implementation of readline that uses |
|
204 | 207 | native Windows calls through :mod:`ctypes`. The easiest way of installing |
|
205 | 208 | PyReadline is you use the binary installer available `here |
|
206 | 209 | <http://pypi.python.org/pypi/pyreadline>`__. |
|
207 | 210 | |
|
208 | 211 | On OSX, if you are using the built-in Python shipped by Apple, you will be |
|
209 | 212 | missing a full readline implementation as Apple ships instead a library called |
|
210 | 213 | ``libedit`` that provides only some of readline's functionality. While you may |
|
211 | 214 | find libedit sufficient, we have occasional reports of bugs with it and several |
|
212 | 215 | developers who use OS X as their main environment consider libedit unacceptable |
|
213 | 216 | for productive, regular use with IPython. |
|
214 | 217 | |
|
215 | 218 | Therefore, we *strongly* recommend that on OS X you get the full |
|
216 | 219 | :mod:`readline` module. We will *not* consider completion/history problems to |
|
217 | 220 | be bugs for IPython if you are using libedit. |
|
218 | 221 | |
|
219 | 222 | To get a working :mod:`readline` module, just do (with :mod:`setuptools` |
|
220 | 223 | installed): |
|
221 | 224 | |
|
222 | 225 | .. code-block:: bash |
|
223 | 226 | |
|
224 | 227 | $ easy_install readline |
|
225 | 228 | |
|
226 | 229 | .. note:: |
|
227 | 230 | |
|
228 | 231 | Other Python distributions on OS X (such as fink, MacPorts and the official |
|
229 | 232 | python.org binaries) already have readline installed so you likely don't |
|
230 | 233 | have to do this step. |
|
231 | 234 | |
|
232 | 235 | When IPython is installed with :mod:`setuptools`, (e.g. using the |
|
233 | 236 | ``easy_install`` command), readline is added as a dependency on OS X, and |
|
234 | 237 | PyReadline on Windows, and will be installed on your system. However, if you |
|
235 | 238 | do not use setuptools, you may have to install one of these packages yourself. |
|
236 | 239 | |
|
237 | 240 | |
|
238 | 241 | nose |
|
239 | 242 | ---- |
|
240 | 243 | |
|
241 | 244 | To run the IPython test suite you will need the :mod:`nose` package. Nose |
|
242 | 245 | provides a great way of sniffing out and running all of the IPython tests. The |
|
243 | 246 | simplest way of getting nose is to use :command:`easy_install` or :command:`pip`: |
|
244 | 247 | |
|
245 | 248 | .. code-block:: bash |
|
246 | 249 | |
|
247 | 250 | $ pip install nose |
|
248 | 251 | |
|
249 | 252 | Another way of getting this is to do: |
|
250 | 253 | |
|
251 | 254 | .. code-block:: bash |
|
252 | 255 | |
|
253 | 256 | $ pip install ipython[test] |
|
254 | 257 | |
|
255 | 258 | For more installation options, see the `nose website |
|
256 | 259 | <http://somethingaboutorange.com/mrl/projects/nose/>`_. |
|
257 | 260 | |
|
258 | 261 | Once you have nose installed, you can run IPython's test suite using the |
|
259 | 262 | iptest command: |
|
260 | 263 | |
|
261 | 264 | .. code-block:: bash |
|
262 | 265 | |
|
263 | 266 | $ iptest |
|
264 | 267 | |
|
265 | pexpect | |
|
266 | ------- | |
|
267 | ||
|
268 | The pexpect_ package is used in IPython's :command:`irunner` script, as well as | |
|
269 | for managing subprocesses. IPython now includes a version of pexpect in | |
|
270 | :mod:`IPython.external`, but if you have installed pexpect, IPython will use | |
|
271 | that instead. On Unix platforms (including OS X), just do: | |
|
272 | ||
|
273 | .. code-block:: bash | |
|
274 | ||
|
275 | $ pip install pexpect | |
|
276 | ||
|
277 | .. note:: | |
|
278 | ||
|
279 | On Python 3, you should actually install :mod:`pexpect-u`, | |
|
280 | a unicode-safe fork of pexpect. | |
|
281 | ||
|
282 | Windows users are out of luck as pexpect does not run there. | |
|
283 | ||
|
284 | 268 | Dependencies for IPython.parallel (parallel computing) |
|
285 | 269 | ====================================================== |
|
286 | 270 | |
|
287 | 271 | IPython.parallel provides a nice architecture for parallel computing, with a |
|
288 | 272 | focus on fluid interactive workflows. These features require just one package: |
|
289 | 273 | PyZMQ. See the next section for PyZMQ details. |
|
290 | 274 | |
|
291 | 275 | On a Unix style platform (including OS X), if you want to use |
|
292 | 276 | :mod:`setuptools`, you can just do: |
|
293 | 277 | |
|
294 | 278 | .. code-block:: bash |
|
295 | 279 | |
|
296 | 280 | $ easy_install ipython[zmq] # will include pyzmq |
|
297 | 281 | |
|
298 | 282 | Security in IPython.parallel is provided by SSH tunnels. By default, Linux |
|
299 | 283 | and OSX clients will use the shell ssh command, but on Windows, we also |
|
300 | 284 | support tunneling with paramiko_. |
|
301 | 285 | |
|
302 | 286 | Dependencies for IPython.kernel.zmq |
|
303 | 287 | =================================== |
|
304 | 288 | |
|
305 | 289 | pyzmq |
|
306 | 290 | ----- |
|
307 | 291 | |
|
308 | 292 | IPython 0.11 introduced some new functionality, including a two-process |
|
309 | 293 | execution model using ZeroMQ_ for communication. The Python bindings to ZeroMQ |
|
310 | 294 | are found in the PyZMQ_ project, which is easy_install-able once you have |
|
311 | 295 | ZeroMQ installed. If you are on Python 2.6 or 2.7 on OSX, or 2.7 on Windows, |
|
312 | 296 | pyzmq has eggs that include ZeroMQ itself. |
|
313 | 297 | |
|
314 | 298 | IPython.kernel.zmq depends on pyzmq >= 2.1.4. |
|
315 | 299 | |
|
316 | 300 | Dependencies for the IPython QT console |
|
317 | 301 | ======================================= |
|
318 | 302 | |
|
319 | 303 | pyzmq |
|
320 | 304 | ----- |
|
321 | 305 | |
|
322 | 306 | Like the :mod:`IPython.parallel` package, the QT Console requires ZeroMQ and |
|
323 | 307 | PyZMQ. |
|
324 | 308 | |
|
325 | 309 | Qt |
|
326 | 310 | -- |
|
327 | 311 | |
|
328 | 312 | Also with 0.11, a new GUI was added using the work in :mod:`IPython.kernel.zmq`, which |
|
329 | 313 | can be launched with ``ipython qtconsole``. The GUI is built on Qt, and works |
|
330 | 314 | with either PyQt, which can be installed from the `PyQt website |
|
331 | 315 | <http://www.riverbankcomputing.co.uk/>`_, or `PySide |
|
332 | 316 | <http://www.pyside.org/>`_, from Nokia. |
|
333 | 317 | |
|
334 | 318 | pygments |
|
335 | 319 | -------- |
|
336 | 320 | |
|
337 | 321 | The syntax-highlighting in ``ipython qtconsole`` is done with the pygments_ |
|
338 | 322 | project, which is easy_install-able. |
|
339 | 323 | |
|
340 | 324 | .. _installnotebook: |
|
341 | 325 | |
|
342 | 326 | Dependencies for the IPython HTML notebook |
|
343 | 327 | ========================================== |
|
344 | 328 | |
|
345 | 329 | The IPython notebook is a notebook-style web interface to IPython and can be |
|
346 | 330 | started with the command ``ipython notebook``. |
|
347 | 331 | |
|
348 | 332 | pyzmq |
|
349 | 333 | ----- |
|
350 | 334 | |
|
351 | 335 | Like the :mod:`IPython.parallel` and :mod:`IPython.frontend.qt.console` |
|
352 | 336 | packages, the HTML notebook requires ZeroMQ and PyZMQ. |
|
353 | 337 | |
|
354 | 338 | Tornado |
|
355 | 339 | ------- |
|
356 | 340 | |
|
357 | 341 | The IPython notebook uses the Tornado_ project for its HTTP server. Tornado 2.1 |
|
358 | 342 | is required, in order to support current versions of browsers, due to an update |
|
359 | 343 | to the websocket protocol. |
|
360 | 344 | |
|
361 | 345 | Jinja |
|
362 | 346 | ----- |
|
363 | 347 | |
|
364 | 348 | The IPython notebook uses the Jinja_ templating tool to render HTML pages. |
|
365 | 349 | |
|
366 | 350 | |
|
367 | 351 | MathJax |
|
368 | 352 | ------- |
|
369 | 353 | |
|
370 | 354 | The IPython notebook uses the MathJax_ Javascript library for rendering LaTeX |
|
371 | 355 | in web browsers. Because MathJax is large, we don't include it with |
|
372 | 356 | IPython. Normally IPython will load MathJax from a CDN, but if you have a slow |
|
373 | 357 | network connection, or want to use LaTeX without an internet connection at all, |
|
374 | 358 | you can install MathJax locally. |
|
375 | 359 | |
|
376 | 360 | A quick and easy method is to install it from a python session:: |
|
377 | 361 | |
|
378 | 362 | from IPython.external.mathjax import install_mathjax |
|
379 | 363 | install_mathjax() |
|
380 | 364 | |
|
381 | 365 | If you need tighter configuration control, you can download your own copy |
|
382 | 366 | of MathJax from http://www.mathjax.org/download/ - use the MathJax-2.0 link. |
|
383 | 367 | When you have the file stored locally, install it with:: |
|
384 | 368 | |
|
385 | 369 | python -m IPython.external.mathjax /path/to/source/mathjax-MathJax-v2.0-20-g07669ac.zip |
|
386 | 370 | |
|
387 | 371 | For unusual needs, IPython can tell you what directory it wants to find MathJax in:: |
|
388 | 372 | |
|
389 | 373 | python -m IPython.external.mathjax -d /some/other/mathjax |
|
390 | 374 | |
|
391 | 375 | By default Mathjax will be installed in your ipython profile directory, but you |
|
392 | 376 | can make system wide install, please refer to the documentation and helper function |
|
393 | 377 | of :mod:`IPython.external.mathjax` |
|
394 | 378 | |
|
395 | 379 | Browser Compatibility |
|
396 | 380 | --------------------- |
|
397 | 381 | |
|
398 | 382 | The IPython notebook is officially supported on the following browers: |
|
399 | 383 | |
|
400 | 384 | * Chrome ≥ 13 |
|
401 | 385 | * Safari ≥ 5 |
|
402 | 386 | * Firefox ≥ 6 |
|
403 | 387 | |
|
404 | 388 | The is mainly due to the notebook's usage of WebSockets and the flexible box model. |
|
405 | 389 | |
|
406 | 390 | The following browsers are unsupported: |
|
407 | 391 | |
|
408 | 392 | * Safari < 5 |
|
409 | 393 | * Firefox < 6 |
|
410 | 394 | * Chrome < 13 |
|
411 | 395 | * Opera (any): CSS issues, but execution might work |
|
412 | 396 | * Internet Explorer < 10 |
|
413 | 397 | |
|
414 | 398 | The following specific combinations are known **NOT** to work: |
|
415 | 399 | |
|
416 | 400 | * Safari, IPython 0.12, tornado ≥ 2.2.0 |
|
417 | 401 | * Safari with HTTPS connection to notebook and an untrusted certificate (websockets will fail) |
|
418 | 402 | * The [diigo Chrome extension](http://help.diigo.com/tools/chrome-extension) seems to interfere with scrolling |
|
419 | 403 | |
|
420 | 404 | There are some early reports that the Notebook works on Internet Explorer 10, but we |
|
421 | 405 | expect there will be some CSS issues related to the flexible box model. |
|
422 | 406 | |
|
423 | 407 | |
|
424 | 408 | Dependencies for nbconvert (converting notebooks to various formats) |
|
425 | 409 | ==================================================================== |
|
426 | 410 | |
|
427 | 411 | pandoc |
|
428 | 412 | ------ |
|
429 | 413 | |
|
430 | 414 | The most important dependency of nbconvert is Pandoc_ 1.10 or later, a document format translation program. |
|
431 | 415 | This is not a Python package, so it cannot be expressed as a regular IPython dependency with setuptools. |
|
432 | 416 | |
|
433 | 417 | To install pandoc on Linux, you can generally use your package manager:: |
|
434 | 418 | |
|
435 | 419 | sudo apt-get install pandoc |
|
436 | 420 | |
|
437 | 421 | On other platforms, you can get pandoc from `their website <http://johnmacfarlane.net/pandoc/installing.html>`_. |
