我尝试在 ppc64le 架构中使用 torchmeta。不幸的是，安装起来并不容易，因为 ppc64le 需要特殊的二进制文件才能工作。
我最终按照这些说明成功获得了 pytorch 和 torchvision 的正确二进制文件（在正确的 ibm 通道前面加上 conda 二进制文件，并且还安装了所有必需的文件）：
conda config --prepend channels https://public.dhe.ibm.com/ibmdl/export/pub/software/server/ibm-ai/conda/
conda create -n my_new_env python=3.7 powerai=1.7.0
conda activate my_new_env
之后我继续安装正确版本的torchmeta，这是1.3.1
，因为ppc64le只有pytorch
1.3.1和torchvision
0.4.2。所以我就这么做了：
pip install torchmeta==1.3.1
但现在我有一个新错误，它无法找到与我想做的事情兼容的 h5py 的正确版本。错误消息太大，无法粘贴，但我将粘贴我希望其中有用的部分：

ERROR: Failed building wheel for h5py
Running setup.py clean for h5py
Failed to build h5py
DEPRECATION: Could not build wheels for h5py which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

有人知道如何在 ppc64le 中成功安装工作的 torchmeta 版本（使用 wmcle 1.7.0）吗？
https://docs.h5py.org/en/stable/build.html#source-installation。
从 conda 安装 h5py 或安装所需的构建依赖项。
