安裝的Anaconda3，安裝程序一切正常，安裝完成后運行Jupyter Notebook出現了一些問題：
問題一：Jupyter Notebook的啟動地址問題
啟動后，瀏覽器地址欄顯示的地址為：http://localhost:8889/undefined/tree，而不是：http://localhost:8889/tree，如下圖。
問題二：新建檔案報錯
新建檔案直接報錯，錯誤提示如下（應該還是地址的問題）：
終端命令如下：

看日志像后臺服務出錯了。uj5u.com熱心網友回復：
反正Python環境容易出問題，我也是，同樣的代碼，本來運行沒問題，過一會兒用jupyter notebook運行報錯，重啟notebook代碼又能正常運行uj5u.com熱心網友回復：
這里有幾種安裝方式，可以試一下：https://www.hellodemos.com/hello-jupyter/jupyter-install.html轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/105057.html
