Question

我正在尝试在操作系统更新后安装tensorflow。我收到[Errno 13]权限被拒绝。我检查过的所有论坛帖子都建议使用虚拟环境解决此问题。问题是我已经在虚拟环境中工作。

这是我使用的命令：

user@Computer:~$ cd /tensorflow
user@Computer:/tensorflow$ virtualenv --system-site-packages -p python3 venv
user@Computer:/tensorflow$ source /tensorflow/venv/bin/activate
(venv) user@Computer:/tensorflow$ pip install -U tensorflow-GPU

这是我得到的输出：

(venv) user@Computer:/tensorflow$ pip install -U tensorflow-GPU

包含'--user'选项可得到以下结果

Will not install to the user site because it will lack sys.path precedence to setuptools in /tensorflow/venv/lib/python3.6/site-packages

Answer 1

我做了一些进一步的挖掘。

显然，virtualenv是使用sudo创建的，因此我需要更改权限。

详细信息在这里： How to avoid "Permission denied" when using pip with virtualenv

具体是

sudo chown -R your_username:your_username path/to/virtuaelenv/

Errno 13许可被拒绝。已经在虚拟环境中
