安装时使用国内镜像链接 阿里云 http:// mirrors.aliyun.com/pypi /simple/ 中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 豆瓣(douban) http:// pypi.douban.com/simple/ 清华大学 https:// pypi.tuna.tsinghua.edu.cn /simple/ 中国科学技术大学 http:// pypi.mirrors.ustc.edu.cn /simple/ 使用指令指定源: pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python 秒秒种成功安装 还有scarpy安装很烦 所以使用conda install scrapy也很快（必须安装anaconda） 来源： oschina 链接： https://my.oschina.net/u/4269500/blog/3626548

捋一捋少有人知的 Python "重试机制"

How to make a docker image with Anaconda and be able to use GPU?

由 时间秒杀一切 提交于 2021-01-29 19:37:40
问题 I have a GPU, and CUDA driver installed. I am making a docker image using the official anaconda image available at docker hub.

Install nvidia-container-runtime and use the docker run --gpus all flag with your Anaconda container. Remember, that you can run Windows
