标题: 计算棒上安装opencv报错

运行demo脚本时提示没有cv2模块，通过pip安装总是报错，请问有没有什么解决建议：

[toybrick@rk1808 rockx]$ python3 -m pip install opencv-python --user
ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: none)
ERROR: No matching distribution found for opencv-python

[toybrick@rk1808 rockx]$ pip3 install opencv-python --user -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

我贴了两种报错的情况，最开始没有指定源，应该缺省用官方源吧。

试下dnf install python3-opencv 有没有

[toybrick@rk1808 dnf]$ sudo dnf install python3-opencv
Error: Failed to synchronize cache for repo 'fedora-modular'

在网上找了些别人的解决方法，试过了都不行。

你这不行是跟官方dnf源连不上，先让1808能访问外网，再dnf clean /update/upgrade 然后安装cv

谢谢，dnf update后安装成功了。

后面pip安装 rockx 又不行了，要麻烦再帮忙看看：
[toybrick@rk1808 ~]$ python3 -m pip install --user rockx

你这是改了我们官方源么？rockx在我们官方源上才有，直接安装当然没有。
如果你不是toybrick的产品，那你需要自己手动拷贝发布包进去安装，请询问你的代理商

通过指定上面的地址安装成功了。
