superset load_examples加載樣例報錯 ：
urllib.error.URLError: <urlopen error [Errno 111] Connection refused>
好像不太影響superset的搭建
又執行了下superset load_examples 提示如下，已經加載了一部分，加載到San Francisco population polygons時候拒絕鏈接了

再次執行了下superset load_examples 提示如下，table sf_population_polygons加載成功了，到下一個樣例報錯拒絕訪問，所以個人猜測：可能是因爲訪問國外服務器不太穩定的原因,但是隻是缺少樣例圖表，應該不影響superset的使用

就當是未完全加載examples，只是樣例少了點兒，但是應該不影響後續執行，繼續
#初始化
superset init
#運行
superset run -p 8088 --with-threads --reload --debugger
如下圖：代表成功了，如果是在本地虛擬機上搭建的，直接訪問http://127.0.0.1:8088/就可以看到炫酷的可視化圖表了，可惜我這是在阿里雲ESC服務器上，替換成公網IP還是不行，這個是我在之前用Django搭建自己博客時候遇到的問題，個人博客也是止步於此！
正常superset測試到這裏結束了
後續繼續解決訪問服務器的問題
