上記の問題を解決した後、opencvを含む新しい環境を新規作成し、spyder 3.3.3をインストールして有効にした後、

という問題に遭遇しました.

問題の原因を探る
pyCharmを使用して起動すると、次のようなヒントが得られます.

Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart PyCharm

flyfish 1986の答えに感謝します.エラーの原因はファイアウォールです.
PS:問題2の原因はopencvライブラリ(または追加ライブラリ)が新たに追加され、windowsファイアウォールによるプログラム通信の阻害である.
解決策
方法1:
Windowsファイアウォールでは、次のプログラムE:Anaconda 3pythonw.exe E:Anaconda 3pytho.exeがファイアウォールを通過し、spyder 3.3.2のIPythonが正常に動作します!!!
方法2
他のライブラリがインストールされているため、問題2が発生したため、Windowsファイアウォールが閉じられ、この問題は解消されました.spyder 3.3.3のIPythonも成功!!!
