錯誤出在這裡, from . 是相對路徑, 顯然你的 python 沒設定好.

from . import scimath as emath

最簡單的就是用安裝一個anaconda發行版的 python, 別再自己折騰了, 數值計算那幾個package 安裝麻煩的很, 小毛病一堆, 而且windows估計更麻煩.

PS: 學會怎麼搜尋, http://stackoverflow.com/questions/26238004/ipython-notebook-throws-importerror-ipython-doesnt. 關鍵字"cannot import name scimath" 前三個搜尋結果全部都是相關解決方案, 怎麼會搜不到
