Question

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。但是，如图here所示，尝试conda install -c anaconda tensorflow-gpu时。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',))",),)

有什么理由？

Answer 1

有两种类型的张量流：

仅支持CPU的TensorFlow
支持GPU的TensorFlow

您必须选择安装TensorFlow的机制。支持的选择如下：

virtualenv
using pip
Docker
Anaconda

我使用pip

安装在终端

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

要卸载，请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

Answer 2

对于可能不知道-c或--channel选项的人，会为channel添加conda来搜索该包。

请尝试下面的内容：

anaconda logout
conda update conda

而不是尝试重新安装
