Arg. The ipython install is a little idiosyncratic. Here’s what I had to do to resolve this: $ pip uninstall ipython $ pip install “ipython[all]” The issue is that notebooks have their own set of dependencies, which aren’t installed with pip install ipython. However, having installed ipython, pip doesn’t see the need to add anything … Read more
One reason can be remembed locations. You can clear the cached locations by issuing following command: hash -r SIDENOTE: Instead of which, using type command, you can see the hashed location: $ type pip pip is /usr/local/bin/pip $ pip -V pip 1.5.6 from /usr/local/lib/python2.7/dist-packages (python 2.7) $ type pip pip is hashed (/usr/local/bin/pip)
This is not recommended, as it hard-codes a path and makes it difficult to run the script elsewhere, but you can do >>> import sys >>> sys.path.insert(0,’/home/anand/’) >>> print(sys.path) [‘/home/anand/’, ”, ‘/usr/local/lib/python2.7/dist-packages/_pdbpp_path_hack’, ‘/usr/local/lib/python2.7/dist-packages/goose-0.0.1-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/jieba-0.33-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/cssselect-0.9.1-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/nanoservice-0.1.5-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/nanomsg-1.0a2-py2.7-linux-x86_64.egg’, ‘/usr/local/lib/python2.7/dist-packages/msgpack_python-0.4.2-py2.7-linux-x86_64.egg’, ‘/usr/local/lib/python2.7/dist-packages/DecisionTree-2.2.5-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/nudepy-0.2-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/wsgilog-0.3-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/distribute-0.7.3-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/PIL-1.1.7-py2.7-linux-x86_64.egg’, ‘/usr/local/lib/python2.7/dist-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg’, ‘/usr/local/lib/python2.7/dist-packages/munkres-1.0.7-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/parsedatetime-1.4-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/argparse-1.3.0-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/tusker-0.1-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/SQLAlchemy-1.0.3-py2.7-linux-x86_64.egg’, ‘/usr/local/lib/python2.7/dist-packages/numpy-1.9.2-py2.7-linux-x86_64.egg’, ‘/usr/local/lib/python2.7/dist-packages/turkic-0.2.5-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/scikits.bootstrap-0.3.2-py2.7.egg’, ‘/usr/local/lib/python2.7/dist-packages/pyvision-0.1-py2.7-linux-x86_64.egg’, ‘/home/anand/playspace/languages/python_pkgs/ets’, ‘/usr/local/lib/python2.7/dist-packages/Scrapy-1.1.0dev1-py2.7.egg’, … Read more
setuptools.setup() calls distutils.core.setup() and passes it’s own **kwargs as the only parameter, so any keywords that distutils accepts will also be accepted by setuptools. If we go look at distutils setup_keywords = (‘distclass’, ‘script_name’, ‘script_args’, ‘options’, ‘name’, ‘version’, ‘author’, ‘author_email’, ‘maintainer’, ‘maintainer_email’, ‘url’, ‘license’, ‘description’, ‘long_description’, ‘keywords’, ‘platforms’, ‘classifiers’, ‘download_url’, ‘requires’, ‘provides’, ‘obsoletes’, ) Most … Read more
This solution is suitable in cases where no virtualenv is available system wide and you can not become root to install virtualenv. When I set up a debian for python development or deployment I always apt-get install python-virtualenv. It is more convenient to have it around than to do the bootstrap pointed out below. But … Read more
As of version 9.0.1 pip will honor a new python_requires string, specifying the Python version required for installation, e.g, for example if one wishes to enforce minimum Python version of 3.3: setup( …, python_requires=”>=3.3″ ) See here for more details. See also this answer on SO.
Don’t know if you solved the problem but if anyone has this problem in future. $python >>import numpy >>print(numpy) Go to the location printed and delete the numpy installation found there. You can then use pip or easy_install
I’ve achieved this by committing a slight abuse of extra requirements. You were almost there trying the extras syntax, just that tests_require deps aren’t automatically available that way. With a setup.py like this: from setuptools import setup test_deps = [ ‘coverage’, ‘pytest’, ] extras = { ‘test’: test_deps, } setup( # Other metadata… tests_require=test_deps, extras_require=extras, … Read more
Regrettably, there’s no method to the madness. The name in the package index is independent of the module name you import. Disastrously some packages share module names. If you install both, your application will break with even odds. (Ruby has this problem too) Packaging in Python is generally dire. The root cause is that the … Read more
I’d still like to know where to set that reference to vsvarsall.bat… Well, as martineau wrote you have to have either Visual Studio 2008 or Visual C++ Express installed. Having said that I understand you would like to know where Python looks for this batch file. You can see this by looking at definition of … Read more
