当尝试在 Anaconda 上安装 Tensorflow 时，我尝试了两种类型的命令。conda install tensorflow-gpu工作得很好。然而，当尝试conda install -c anaconda tensorflow-gpu如图所示here https://anaconda.org/anaconda/tensorflow-gpu。它给出以下错误消息。
Fetching package metadata ...
CondaHTTPError: HTTP None None for url <https://conda.anaconda.org/anaconda/linux-64/repodata.json>
Elapsed: None
An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
ConnectionError(MaxRetryError("HTTPSConnectionPool(host='conda.anaconda.org', port=443): Max retries exceeded with url: /anaconda/linux-64/repodata.json (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x2b8e3f4ec110>: Failed to establish a new connection: [Errno -2] Name or service not known',))",),)
可能是什么原因呢？
张量流有两种类型：
- 仅支持 CPU 的 TensorFlow
- 具有 GPU 支持的 TensorFlow
您必须选择安装 TensorFlow 的机制。支持的选择如下：
虚拟环境 https://www.tensorflow.org/install/install_linux#InstallingVirtualenv
使用点 https://www.tensorflow.org/install/install_linux#InstallingNativePip
Docker https://www.tensorflow.org/install/install_linux#InstallingDocker
Anaconda https://www.tensorflow.org/install/install_linux#InstallingAnaconda
我使用 pip 给出步骤
To install在终端中运行以下命令
sudo apt-get install python-pip python-dev # for Python 2.7
sudo apt-get install python3-pip python3-dev # for Python 3.n
pip install tensorflow # Python 2.7; for CPU support
pip3 install tensorflow # Python 3.n; for CPU support
pip install tensorflow-gpu # Python 2.7; for GPU support
pip3 install tensorflow-gpu # Python 3.n; for GPU support
To 卸载在终端中运行以下命令：
sudo pip uninstall tensorflow # for Python 2.7
sudo pip3 uninstall tensorflow # for Python 3.n
