当我尝试运行代码时出现错误 ( https://github.com/dmlc/dgl/blob/master/examples/pytorch/han/main.py )

来自 DGL
( https://github.com/dmlc/dgl )

它需要 CUDA 和 Pytorch，所以我设法安装了它。

但是我遇到了错误并且无法通过 Google/Stackoverflow 搜索找到解决方案

我的环境是

Linux minsky 3.10.0-957.5.1.el7.ppc64le

CentOS

Python 3.6.9

conda 4.5.11

CUDA 10.1

NVCC 10.1

pytorch 0.4.0

Torchvision 0.2.1

Pytorch 在 Python 中运行良好

>>> import torch
>>> print (torch.__version__)
0.4.0
>>> import torchvision
>>> print (torchvision.__version__)
0.2.1

请你能帮我一下吗？

* DGL 从源代码安装

** Pytorch 与来自 channel:engility( How to install pytorch on Power 8 or PPC64 machine? ) 的 conda 一起安装

conda install -c engility pytorch

因为其他方式(默认 conda、pip、从源代码安装)永远不适用于 ppc64le

tl;博士 升级到 PyTorch 0.4。 1

请注意，DGL 需要 PyTorch 0.4.1，而您使用的是 PyTorch 0.4.0。如果你仔细观察，你会看到 as_tensor是 proposed in 30 Apr 2018并于 2018 年 5 月 1 日合并。您还会看到 PyTorch 0.4.0 在 2018 年 4 月 24 日之前发布，而 PyTorch 0.4.1于 2018 年 7 月 26 日之后发布。实际上，如果您查看 changelog of the 0.4.1 version ，您会注意到宣布了一个新的运营商:torch.as_tensor :)
