Question

当前版本堆栈：

python 3.5

tensorflow                    1.14.0                
tensorflow-estimator          1.14.0                
tensorflow-gpu                1.14.0                
tensorflow-tensorboard        0.1.8 

protobuf                      3.9.1

Keras                         2.2.4                 
Keras-Applications            1.0.7                 
Keras-Preprocessing           1.0.9

驱动程序和机器：

Ubuntu 16.04 , NVIDIA-SMI 396.54 , CUDA - 9.0 , CuDnn 7 , libcudnn - 7.4.1

摘要-

无法从tensorflow.python.keras._impl.keras.backend上的Abs导入 tensorflow-gpu == 1.14.0

并且无法在tensorflow-gpu == 1.8.0上获取CheckpointableBase属性

哪个tensorflow-gpu和keras版本同时支持CheckpointableBase属性和tensorflow.python.keras._impl.keras.backend中的'abs'？

详细信息-

我目前正在用Keras == 2.2.4训练问题端口掩码rcnn。根据一些threads的说法，为了获得Abs，我尝试将tensorflow-gpu更新为1.8.0，并更新了protobuf。虽然我当时能够导入abs，但最终在tensorflow-gpu上收到“ AttributeError：模块'tensorflow.python.training.checkpointable'没有属性'CheckpointableBase'”到1.8.0。然后为了获取CheckpointableBase，再次指向一些线程更新tensorflow-gpu == 1.14.0。

Answer 1

嗨，

我能够通过从dist-packages目录本身中删除所有tensorFlow和keras python3软件包，使用pip3卸载并再次安装tensorflow == 1.8.0
来解决此问题。 tensorflow-gpu == 1.8.0，Keras == 2.2.4

（引起此特定错误的潜在原因是python在解包目录中引用了多个tensoflow-gpu，keras版本的软件包文件。尽管通过pip3安装了特定的tensoflow-gpu，keras版本应该理想地删除先前的现有版本。但是就我而言，这没有发生。）

解决方案：

使用$ locate --basename '\tensorflow'命令（如果您使用的是Ubuntu）在dist-packages目录中找到tensorflow和keras软件包。就我而言，是

$查找--basename'\ tensorflow'

输出-

/usr/local/lib/python3.5/dist-packages/tensorflow
/usr/local/lib/python3.5/dist-packages/tensorflow/include/tensorflow
/usr/share/nginx/html/projects/python/machine-learning/objectDetection/models-master/research/syntaxnet/tensorflow

＆

$查找--basename'\ keras'

输出-

/usr/local/lib/python3.5/dist-packages/keras
/usr/local/lib/python3.5/dist-packages/tensorflow/keras
/usr/local/lib/python3.5/dist-packages/tensorflow/contrib/keras
/usr/local/lib/python3.5/dist-packages/tensorflow/contrib/keras/api/keras
/usr/local/lib/python3.5/dist-packages/tensorflow/python/keras
/usr/local/lib/python3.5/dist-packages/tensorflow/python/keras/_impl/keras
/usr/local/lib/python3.5/dist-packages/tensorflow/tools/api/generator/api/keras
/usr/share/nginx/html/projects/python/Playground/lambda/testkeras/keras

现在您已经知道所需的软件包位置。只需使用以下命令删除tensorflow和keras目录并卸载软件包

删除目录

sudo rm -R /usr/local/lib/python3.5/dist-packages/tensorflow/
sudo rm -R /usr/share/nginx/html/projects/python/machine-learning/objectDetection/models-master/research/syntaxnet/tensorflow

sudo rm -R /usr/local/lib/python3.5/dist-packages/keras/
sudo rm -R /usr/share/nginx/html/projects/python/Playground/lambda/testkeras/keras

使用pip3卸载

sudo pip3 uninstall tensorflow
sudo pip3 uninstall tensorflow-gpu
sudo pip3 uninstall keras

再次安装tensorflow，tensorflow-gpu，keras

sudo pip3 install tensorflow == 1.8.0
须藤pip3 install tensorflow-gpu == 1.8.0 sudo pip3 install Keras == 2.2.4

ImportError：无法从tensorflow.python.keras._impl.keras.backend
