問題描述
我在 iPython 中運行以下代碼:
I am running the following code in iPython:
import multiprocessing
def my_function(x):
"""The function you want to compute in parallel."""
x += 1
return x
if __name__ == '__main__':
pool = multiprocessing.Pool()
results = pool.map(my_function, [1,2,3,4,5,6])
print(results)
在 Windows 上的 ipython QT 控制臺中.但是，代碼不起作用——QT 控制臺只是凍結了.這個問題是 iPython 特有的(上面的代碼應該適用于常規的 Python 2.7).
in ipython QT console on Windows. However, the code does not work -- the QT console just freezes up. The issue is specific to iPython (the code above should work for the regular Python 2.7).
有什么解決辦法嗎?

來自 文檔:
注意
此包中的功能要求 __main__ 模塊是孩子們可以導入.這在編程指南中有介紹但是值得在這里指出.這意味著一些例子，比如 multiprocessing.Pool 的例子在交互式解釋器
Functionality within this package requires that the __main__ module be
importable by the children. This is covered in Programming guidelines
however it is worth pointing out here. This means that some examples,
such as the multiprocessing.Pool examples will not work in the
interactive interpreter
這篇關于多處理在 Python 中工作，但不在 iPython 中的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網！
