I never see that in any online python projects....??? In addition, native namespace package support has been implemented (see PEP 420). 5.1. importlib¶ The importlib module provides a rich API for interacting with the import system.

Python Cannot Find Module In Site-packages

Path entry finder protocol¶ In order to support imports of modules and initialized packages and also to contribute portions to namespace packages, path entry finders must implement the find_spec() method. Open issues¶ XXX It would be really nice to have a diagram. Local addons go into /usr/local/lib/python/dist-packages, Debian addons install into /usr/{lib,share}/python/dist-packages. /usr/lib/python/site-packages is not used.

OK so there you have it. import sys import pprint print 'PATH:', pprint.pprint(sys.path) print print 'IMPORTERS:' for name, cache_value in sys.path_importer_cache.items(): name = name.replace(sys.prefix, '...') print '%s: %r' % (name, cache_value) A cache value of None means

The default contents of the path include the directory of the script used to start the application and the current working directory. Older path entry finders may implement one of these two deprecated methods instead of find_spec(). Footnotes [1]See types.ModuleType. [2]The importlib implementation avoids using the return value directly. How To Add To Pythonpath Keep those puppies in their warm, snuggly project subdirectories.

Most path entries name locations in the file system, but they need not be limited to this. Python Cannot Find Installed Module Python member gvanrossum commented Apr 11, 2016 The crash is not very interesting. Non-package modules should not have a __path__ attribute. __file__¶ __cached__¶ __file__ is optional. http://stackoverflow.com/questions/32226316/python-cannot-find-module-in-the-package My environment is Ubuntu 14.04 32-bit; I think I saw this before and after I activated my virtualenv.

If loading fails, the loader must remove any modules it has inserted into sys.modules, but it must remove only the failing module(s), and only if the loader itself has loaded How To Check Pythonpath The import machinery calls the importlib.abc.Loader.exec_module() method with a single argument, the module object to execute. share|improve this answer answered Jan 12 '13 at 17:26 Ryan Artecona 3,13521117 ahhh, nevermind, you already knew most of this –Ryan Artecona Jan 12 '13 at 17:29 add a The original specification for packages is still available to read, although some details have changed since the writing of that document.

Python Cannot Find Installed Module

What do I do? http://www.bdnyc.org/2012/09/editing-pythonpath-to-import-modules/ For backward compatibility with Python 3.3, the module repr will be generated by calling the loader's module_repr() method, if defined, before trying either approach described above. Python Cannot Find Module In Site-packages In reality, what has happened is that the cached bytecode file from our previous failed import attempt is still present and causing trouble, but when Python tries to display the source Python Can't Find Module In Current Directory Some of the features described here may not be available in earlier versions of Python.

Edit Pythonpath

As noted elsewhere, the __main__ module is directly initialized at interpreter startup, much like sys and builtins.

A word of warning: this section and the previous both use the term finder, distinguishing between them by using the terms meta path finder and path entry finder. Python Import Module In Same Directory The package(SOAPpy) I installed by pip is located /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/ And site-package is not in the python path, all I did is add site-packages to PYTHONPATH permanently. 1.Open up Terminal 2.Type open The API for a finder on the meta-path is the same as for a regular path.

There's a reason the general "no package directories on sys.path" guideline exists, and the fact that the interpreter itself doesn't follow it when determining sys.path[0] is the root cause

This name may come from various arguments to the import statement, or from the parameters to the importlib.import_module() or __import__() functions. This is due to the fact that blocks guarded by if __name__ == "__main__": checks only execute when the module is used to populate the __main__ If both find_loader() and find_module() exist on a path entry finder, the import system will always call find_loader() in preference to find_module(). 5.6. Pythonpath Windows import sys import shelve import os filename = '/tmp/pymotw_import_example.shelve' if os.path.exists(filename): os.unlink(filename) db = shelve.open(filename) try: db['data:README'] = """ ============== package README ============== This is the README for ``package``.

New in version 3.4. 5.4.4. In this case, Python will create a namespace package for the top-level parent package whenever it or one of its subpackages is imported. Thus parent/one may not be physically located next to parent/two. http://amigasuperbit.com/python-cannot/python-cannot-find-site-module.html My recommendation: Create a master code directory (called "Modules" or something) in your Documents folder.

Why are wavelengths shorter than visible light neglected by new telescopes? between the finder that creates the module spec and the loader that executes it. Loading 5.4.1. I am seen in darkness and in light, What am I?

A direct call to __import__() performs only the module search and, if found, the module creation operation. The second argument is the path entries to use for the module search.

These were previously performed by the importlib.abc.Loader.load_module() method. 5.4.1. You need to launch python from your '2014_07_13_test' directory. If the path entry is not present in the cache, the path based finder iterates over every callable in sys.path_hooks. To no avail, each time, I enter my python interactive and I get: Python 2.7.3 (default, Aug 1 2012, 05:14:39) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for

Whether using the features of the standard library, or organizing custom code in separate files to make it easier to maintain, understanding and managing the dependencies for a program is an the path based finder). Most of the information is common to all modules. PEP 420 also introduced the find_loader() protocol as an alternative to find_module().

Can a text in Latin be understood by an educated Italian who never had any formal teaching of that language? Changed in version 3.4: In previous versions of Python, finders returned loaders directly, whereas now they return module specs which contain loaders. We recommend upgrading to the latest Safari, Google Chrome, or Firefox.

I just don't know why it would install in the wrong place for this one library, where most others are fine. –roy Jan 12 '13 at 17:59 Option 4:
