IPython ノートブックが間違った tcp アドレスに接続しようとしているようです。簡単な質問は、ノートブックを開いたときに、カーネルを見つけるために接続しようとするアドレスを指定するにはどうすればよいかということです。
ここにいくつかの背景情報があります。スーパーコンピューターへの SSH トンネルを作成しようとしていました。デフォルトの 127.0.0.1:8888 のトンネルをセットアップしました。次に、自分のコンピューターで IPython ノートブックを開始しましたが、アドレスとポートが転送されたため、何らかの競合が発生する可能性があることに気づきました。現在、自分のコンピューターでノートブックを開くと、デッド カーネル ハートビートが発生します。IPython は検索を開始し、127.0.0.1:8888 の通常のページを表示します。エラーが発生するのはノートブックを開くときです。以下は端末出力です。
以下に示すように、ノートブックを起動すると、「接続先: tcp://198.153.192.3:60058」と表示されます。127.0.0.1 であるべきだと思います。これを修正する方法について何か提案はありますか?
