Tensorflow和Keras版本对照及环境安装
在安装tensorflow环境的时候,一定要先弄清楚对应的版本对应的情况,不要上来就pip install tensorflow
,pip install keras
。最后发现全是坑。下面就列一下,tensorflow和keras以及对应的python版本,然后再列一下我成功安装的流程。
一、Tensorflow、Keras和python版本对照
二者对应版本号如表所示(Keras新版本对Tensorflow老版本不兼容,需注意安装版本号)

TensorFlow 1.8 | tensorflow-1.8 | TensorFlow 1.8.0 + Keras 2.1.6 on Python 3.6. |
tensorflow-1.8:py2 | TensorFlow 1.8.0 + Keras 2.1.6 on Python 2. | |
TensorFlow 1.7 | tensorflow-1.7 | TensorFlow 1.7.0 + Keras 2.1.6 on Python 3.6. |
tensorflow-1.7:py2 | TensorFlow 1.7.0 + Keras 2.1.6 on Python 2. | |
TensorFlow 1.5 | tensorflow-1.5 | TensorFlow 1.5.0 + Keras 2.1.6 on Python 3.6. |
tensorflow-1.5:py2 | TensorFlow 1.5.0 + Keras 2.0.8 on Python 2. | |
TensorFlow 1.4 | tensorflow-1.4 | TensorFlow 1.4.0 + Keras 2.0.8 on Python 3.6. |
tensorflow-1.4:py2 | TensorFlow 1.4.0 + Keras 2.0.8 on Python 2. | |
TensorFlow 1.3 | tensorflow-1.3 | TensorFlow 1.3.0 + Keras 2.0.6 on Python 3.6. |
tensorflow-1.3:py2 | TensorFlow 1.3.0 + Keras 2.0.6 on Python 2. |
安装的时候按照对应的版本进行安装。
二、Tensorflow和Keras安装流程
这里安装python=3.6,Tensorflow=2.0,Keras=2.3.1
1. anaconda安装python环境
1)在Anaconda Prompt中输入命令,创建conda环境
conda create -n tensorflow python=3.6
2)激活环境
activate tensorflow
2. 安装Tensorflow
pip install tensorflow==2.0.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
3. 安装Keras
pip install keras==2.3.1 -i https://pypi.tuna.tsinghua.edu.cn/simple
结果查看(切换到python环境):
注意:
如果开始你安装的时候没有注意版本问题,直接使用pip install tensorflow
安装,安装过程中不会出现问题,在import会报错:
W tensorflow/stream_executor/platform/default/dso_loader.cc:59] Could not load dynamic library 'libcudart.so.10.1'; dlerror: libcudart.so.10.1: cannot open shared object file: No such file or directory
I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine.
这就是版本不匹配的问题,你需要安装对应版本的tensorflow。
