|
This is a backport of the `concurrent.futures`_ standard library module to Python 2.
|
|
It should not be installed on Python 3, although there should be no harm in doing so, as the
|
standard library takes precedence over third party libraries.
|
|
To conditionally require this library only on Python 2, you can do this in your ``setup.py``:
|
|
.. code-block:: python
|
|
setup(
|
...
|
extras_require={
|
':python_version == "2.7"': ['futures']
|
}
|
)
|
|
Or, using the newer syntax:
|
|
.. code-block:: python
|
|
setup(
|
...
|
install_requires={
|
'futures; python_version == "2.7"'
|
}
|
)
|
|
.. warning:: The ``ProcessPoolExecutor`` class has known (unfixable) problems on Python 2 and
|
should not be relied on for mission critical work.
