プロジェクトの移行を試みていましたここにリストされています マルチプロセッシングを使用すると、次のエラーが発生します。

Python3ではコードの問題やそれは問題です(3.5.2は私が使用するバージョンです)?

Was trying to migrate the project listed here Which uses multiprocessing, I get the following error:

Is it the problem of code or is it problem in python3 (3.5.2 is the version I use)?

After implementing the suggestion of Patrick Artner more different error comes up but not sure if this is related to earlier error or not:

<事前> <コード> PendingDeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses

それはすべて言います。 Pythonの開発は、 <コード> imp の削除を決定しました。 href="https://docs.python.org/3/library/importlib.html#" REL="NOFOLLOW NOREFERRER"> <コード> importlib - (まだ依然としてコードベース内にあるが削除されます。モジュールのマニュアルに移動し、 imp Codeを importlib コードに変換する方法を読み上げます。

https://docs.python.org/3/library/imp.html.
> バージョン3.4以降の廃止予定:IMPパッケージはImportLibを支持して非推奨を受けることです。

これは warning(今すぐHeed It、PythonをIMPが削除されたバージョンに更新するときに修正する)です。

SO、FE:問題Python 3.4

のIMPからImportLibへの変換

他のものはプログラムがクラッシュします。 https://stackoverflow.com/a/42742804/7505395

を変更することで固定できる可能性があります。 <事前> <コード> event, root = self.context.next()

これに:

<事前> <コード> event, root = context.__next__()

(未テスト)。

 
PendingDeprecationWarning:  the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses 

says it all. The devs on Python decided to remove imp in favor or importlib - it is (yet) still in the codebase but will be removed. Go to the modules documentation and read up on how to translate imp code into importlib code.

https://docs.python.org/3/library/imp.html
Deprecated since version 3.4: The imp package is pending deprecation in favor of importlib.

This is just warning (heed it now, or fix it when you update python to a version where imp is removed).

Search SO, f.e.: Problems when converting from imp to importlib in python 3.4

The other stuff makes the program crash. Curtesy of https://stackoverflow.com/a/42742804/7505395 this might be fixable by changing

event, root = self.context.next()  

to this:

event, root = context.__next__() 

(untested).
