在 python docker 圖像上使用 GPU

Question

我正在使用python:3.7.4-slim-buster docker 圖像，我無法更改它。 我想知道如何在上面使用我的nvidia gpus 。

我通常使用tensorflow/tensorflow:1.14.0-gpu-py3和一個簡單的--runtime=nvidia int docker run命令一切正常，但現在我有這個約束。

我認為這種類型的圖像沒有捷徑，所以我按照本指南https://towardsdatascience.com/how-to-properly-use-the-gpu-within-a-docker-container-4c699c78c6d1構建 Z3254677A7917C6C01FBF55212FZF6它建議：

FROM python:3.7.4-slim-buster

RUN apt-get update && apt-get install -y build-essential
RUN apt-get --purge remove -y nvidia*
ADD ./Downloads/nvidia_installers /tmp/nvidia                             > Get the install files you used to install CUDA and the NVIDIA drivers on your host
RUN /tmp/nvidia/NVIDIA-Linux-x86_64-331.62.run -s -N --no-kernel-module   > Install the driver.
RUN rm -rf /tmp/selfgz7                                                   > For some reason the driver installer left temp files when used during a docker build (i dont have any explanation why) and the CUDA installer will fail if there still there so we delete them.
RUN /tmp/nvidia/cuda-linux64-rel-6.0.37-18176142.run -noprompt            > CUDA driver installer.
RUN /tmp/nvidia/cuda-samples-linux-6.0.37-18176142.run -noprompt -cudaprefix=/usr/local/cuda-6.0   > CUDA samples comment if you dont want them.
RUN export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64         > Add CUDA library into your PATH
RUN touch /etc/ld.so.conf.d/cuda.conf                                     > Update the ld.so.conf.d directory
RUN rm -rf /temp/*  > Delete installer files.

但它引發了一個錯誤：

ADD failed: stat /var/lib/docker/tmp/docker-builder080208872/Downloads/nvidia_installers: no such file or directory

我可以更改什么以輕松讓 docker 圖像看到我的 GPU？

TensorFlow 映像拆分為幾個“部分”Dockerfile。 其中之一包含 TensorFlow 需要在 GPU 上運行的所有依賴項。 使用它您可以輕松創建自定義圖像，您只需將默認 python 更改為您需要的任何版本。 在我看來，這比將 NVIDIA 的東西帶入 Debian 映像（CUDA 和/或 cuDNN 未正式支持 AFAIK）要容易得多。

這是 Dockerfile：

您可以從這里獲取：將 python 版本更改為您需要的版本（在 Ubuntu 存儲庫中可用），添加包、代碼等。
