Queue is in the multiprocessing module so:
队列位于多处理模块中，因此：
from multiprocessing import Queue

You need install Queuelibeither via the Python Package Index (PyPI)or from source.
您需要Queuelib通过Python Package Index (PyPI)源代码或从源代码安装。
To install using pip:-
要使用 pip 安装：-
$ pip install queuelib
To install using easy_install:-
使用 easy_install 安装：-
$ easy_install queuelib
If you have downloaded a source tarball you can install it by running the following (as root):-
如果您已经下载了源代码压缩包，您可以通过运行以下命令（以 root 用户身份）来安装它：-
python setup.py install

import queueis lowercaseqin Python 3.
import queue在 Python 3 中是小写的q。
Change Qto qand it will be fine.
更改Q到q，它会被罚款。

In my case it should be:
就我而言，它应该是：
from multiprocessing import JoinableQueue
from multiprocessing import JoinableQueue
Since in python2, Queue has methods like .task_done(), but in python3 multiprocessing.Queuedoesn't have this method, and multiprocessing.JoinableQueuedoes.
由于在 python2 中， Queue 有类似 的方法.task_done()，但在 python3multiprocessing.Queue中没有这个方法，并且multiprocessing.JoinableQueue有。

I run into the same problem and learn that queue module defines classes and exceptions, that defines the public methods (Queue Objects).
我遇到了同样的问题，并了解到队列模块定义了类和异常，它们定义了公共方法（队列对象）。
Ex.
前任。
workQueue = queue.Queue(10)

It's because of the Python version. In Python 3 it's import Queue as queue; on the contrary in Python 2.x it's import queue. If you want it for both environments you may use something below as mentioned here
这是因为 Python 版本。在 Python 3 中，它是 import Queue as queue; 相反，在 Python 2.x 中它是import queue. 如果您希望在这两种环境中使用它，您可以使用下面提到的内容here
try:
import queue
except ImportError:
import Queue as queue
