Installation

pip install memimport

Usage

import zipextimporter
import sys

sys.path.insert(0, 'path/to/libs.zip')

then

zipextimporter.install()            # default, prefer `hook=False`, `hook=True` as fallback

or

zipextimporter.install(hook=False)  # better compatibility, monkey patch `zipimport.zipimporter`
                                    # equal to empty argument, `hook=True` as fallback

or

zipextimporter.install(hook=True)   # not recommend, install to `sys.path_hooks`

then

import ext_mod_in_zip      # now, support __init__.pyd in packages

ext_mod_in_zip             # <module 'ext_mod_in_zip' from 'path\\to\\libs.zip\\ext_mod_in_zip\\__init__.pyd'>
ext_mod_in_zip.__file__    # 'path\\to\\libs.zip\\ext_mod_in_zip\\__init__.pyd'>
ext_mod_in_zip.__loader__  # <ZipExtensionImporter object 'path\to\libs.zip\'>

import py_mod_in_zip

py_mod_in_zip              # <module 'py_mod_in_zip' from 'path\\to\\libs.zip\\py_mod_in_zip\\__init__.py'>
py_mod_in_zip.__file__     # 'path\\to\\libs.zip\\py_mod_in_zip\\__init__.py'>
py_mod_in_zip.__loader__   # <zipimporter object 'path\to\libs.zip\'>
