python - 没有CUDA？？在 Rstudio 上安装 keras/tensorflow 错误：错误：找不到 Python 模块 tensorflow.python.keras

Question

我正在尝试在 rstudio 上运行 keras。我在服务器上设置了它。当我使用它安装它时它正在工作，install_keras()但我想要 gpu 访问，所以我尝试了install_keras(method = "virtualenv", version = "gpu")，现在当我尝试运行任何命令时出现错误tokenizer <- text_tokenizer(num_words = 20000)。我已经尝试了一切来解决这个问题......

Error: Python module tensorflow.python.keras was not found.

Detected Python configuration:

python:         /data/users/USER/.virtualenvs/r-tensorflow/bin/python
libpython:      /usr/lib64/libpython2.7.so.1.0
pythonhome:     /usr:/usr
virtualenv:     /data/users/USER/.virtualenvs/r-tensorflow/bin/activate_this.py
version:        2.7.5 (default, Jun 11 2019, 12:19:05)  [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]
numpy:          /data/users/USER/.virtualenvs/r-tensorflow/lib/python2.7/site-packages/numpy
numpy_version:  1.16.4
tensorflow:     /data/users/USER/.virtualenvs/r-tensorflow/lib/python2.7/site-packages/tensorflow

python versions found: 
 /data/users/USER/.virtualenvs/r-tensorflow/bin/python
 /usr/bin/python
 /usr/bin/python3
 /data/users/USER/env/bin/python

我认为它使用 libpython2.7 但是当我运行时install_keras(method = "virtualenv", version = "gpu")我不知道要指定哪个 python，我在服务器上安装了 python3.6。

> Sys.which("python")
                                                   python 
"/data/users/USER/.virtualenvs/r-tensorflow/bin/python" 
> use_python("/data/users/USER/.virtualenvs/r-tensorflow/bin/python2.7")
> Sys.which("python")
                                                   python 
"/data/users/USER/.virtualenvs/r-tensorflow/bin/python"

我也试过：

use_condaenv('/data/users/USER/.virtualenvs/r-tensorflow') mnist <- dataset_mnist()

这给出了与上面相同的错误。

我现在在哪里：

编辑：我认为我没有安装 CUDA ... - 这就是我有错误的原因吗？
