worker_manager を機能させようとしていますが、次のエラーが発生し続けます。
Traceback (most recent call last):
File "multiQueue2.py", line 61, in <module>
manager.generate(control, threadName, i)
File "multiQueue2.py", line 38, in generate
target = i.getattr(name)
AttributeError: 'int' object has no attribute 'getattr'
これが私が作業しているコードです。worker_manager は、ライブになる唯一の部分です。辞書からスレッド名を取得し、関連するクラスにアクセスすることになっています。アドバイスはありますか?ありがとう!
