R keras 包：找不到 Python 模块 tensorflow.contrib.keras.python.keras答案

【问题标题】：R keras package: Python module tensorflow.contrib.keras.python.keras was not foundR keras 包：找不到 Python 模块 tensorflow.contrib.keras.python.keras
【发布时间】：2017-07-10 09:08:45
【问题描述】：

Windows 7、Python 3.6（64 位）、RStudio 1.0.143、R 3.4.0

我收到此错误消息，即使它的路径正确到 tensorflow 包：

> library(keras)
> data <- dataset_mnist()
Error: Python module tensorflow.contrib.keras.python.keras was not found.

Detected Python configuration:

python:         C:\Users\mikzhi\AppData\Local\Programs\Python\Python36\\python.exe
libpython:      C:/Users/mikzhi/AppData/Local/Programs/Python/Python36/python36.dll

切换到 Python 3.5.3 没有帮助：

> data <- dataset_mnist()
Error: Python module tensorflow.contrib.keras.python.keras was not found.

【问题讨论】：

试试python3.5。 Keras 仅在此阶段与 Python 2.7-3.5 兼容。 keras.io
我遇到了同样的错误。不知道为什么它声称找到了两个版本（Python35\python.exe 和 Python35\\python.exe）。
在 keras Github repo 中查看这个问题：github.com/rstudio/keras/issues/37

标签： python r windows tensorflow keras

【解决方案1】：

我已经通过运行pip3 install --upgrade tensorflow https://www.tensorflow.org/install/install_windows 解决了这个问题

也许install_tensorflow() 没有完成所有需要的工作。
