這篇文章主要介紹了關于tensorflow和keras版本的對應關系，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

tensorflow和keras版本對應關系

Tensorflow版本	Keras版本
Tensorflow 2.1 Tensorflow 2.0 Tensorflow 1.15	Keras 2.3.1
Tensorflow 1.14	Keras 2.2.5
Tensorflow 1.13 Tensorflow 1.12 Tensorflow 1.11	Keras 2.2.4
Tensorflow 1.10 Tensorflow 1.9	Keras 2.2.0
Tensorflow 1.8 Tensorflow 1.7 Tensorflow 1.5	Keras 2.1.6
Tensorflow 1.4	Keras 2.0.8
Tensorflow 1.3 Tensorflow 1.2 Tensorflow 1.1 Tensorflow 1.0	Keras 2.0.6
Tensorflow 0.12	Keras 1.2.2

tensorflow與keras混用之坑

在使用tensorflow與keras混用是model.save 是正常的但是在load_model的時候報錯了在這里mark 一下

其中錯誤為：TypeError: tuple indices must be integers, not list

再一一番百度后無結(jié)果，上谷歌后找到了類似的問題。但是是一對鳥文不知道什么東西（翻譯后發(fā)現(xiàn)是俄文）。后來谷歌翻譯了一下找到了解決方法。

故將原始問題文章貼上來警示一下

戰(zhàn)斗種族解釋

убераю BatchNormalization всё работает хорошо. Не подскажите в чём ошибка?Выяснил что сохранение keras и нормализация tensorflow не работают вместе нужно просто изменить строку импорта.（譯文：整理BatchNormalization一切正常。不要告訴我錯誤是什么？我發(fā)現(xiàn)保存keras和規(guī)范化tensorflow不能一起工作;只需更改導入字符串即可。)
