最近在K TensorFlow + Keras 深度學習人工智慧實務應用的書籍(上圖)，沒想到各種工具書介紹的安裝方式都會遇到不同版本的錯誤。
下述是安裝好 Anaconda + tensorflow 後要安裝 Keras 遇到的錯誤:

上網查了 Stack overflow (stack overflow 真的是攻城師的好朋友...)

這個問題的解決方法是重新上網抓 html5lib 來覆蓋虛擬環境中的 html5lib 即可，然後重新安裝 keras 就可以裝了。
網址如下:
https://github.com/html5lib/html5lib-python
整包抓下來解壓縮，然後只複製 html5lib 資料夾，接下來就是貼到下圖的位址中(下述網址是已經建立好的 tensorflow 虛擬空間)
然後再重新安裝 keras 就不會遇到錯誤了。
