python - 无法在 Google Colab 中安装 dgl-cu<任何版本>

Question

我尝试在 Google Colab 中使用 dgl 运行图形模型，但在训练模型时继续出现错误。我相信我的主要问题是我无法使用加载 dgl-cuda 库

!pip install dgl-cu111

我收到以下错误:

Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/
ERROR: Could not find a version that satisfies the requirement dgl-cu111 (from versions: none)
ERROR: No matching distribution found for dgl-cu111

训练模型时，出现以下错误:

关于如何在 Google Colab 上安装 dgl-gpu 库有什么想法吗？我正在使用 Colab 的 A100 GPU:

(nvcc:NVIDIA (R) Cuda 编译器驱动程序 版权所有 (c) 2005-2022 NVIDIA 公司 建于 Wed_Sep_21_10:33:58_PDT_2022 Cuda 编译工具，版本 11.8，V11.8.89 构建cuda_11.8.r11.8/compiler.31833905_0)

Answer 1

我在使用 V100 GPU 时遇到了这个问题。我的解决方法是指定来源:

pip install dgl==1.0.1+cu117 -f https://data.dgl.ai/wheels/cu117/repo.html

确保为您的设置选择正确的 CUDA 版本。
