python - 在 Linux 中从 R 运行 keras 时出错

Question

我在 linux 中安装了 keras r 包。然后尝试:

library(keras)
install_keras()

Error: Prerequisites for installing TensorFlow not available. Please install the following Python packages before proceeding: pip, virtualenv

然后我在 linux 中安装了 pip 和 virtual env:

sudo yum install python-pip
sudo pip install virtualenv

然后我再次尝试 install_keras() 并得到以下错误:

Creating virtualenv for TensorFlow at  ~/.virtualenvs/r-tensorflow 
Traceback (most recent call last):
  File "/usr/bin/virtualenv", line 9, in <module>
    load_entry_point('virtualenv==1.10.1', 'console_scripts', 'virtualenv')()
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 299, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2228, in load_entry_point
    raise ImportError("Entry point %r not found" % ((group,name),))

ImportError: Entry point ('console_scripts', 'virtualenv') not found Error: Error 1 occurred creating virtualenv at ~/.virtualenvs/r-tensorflow

如何解决这个问题？
