python - 为 Python 3.8.5 安装 NVIDIA Apex 并与 PyTorch 1.9 兼容

问题描述

我正在运行一个显然需要 NVIDIA apex 的代码（我最初不知道并安装了错误的 apex）。我不确定如何修复最终错误：

(proxy) [jalal@goku proxynca_pp]$ CUDA_VISIBLE_DEVICES=0,1 python train.py --dataset cub  --config config/cub.json --mode train --apex --seed 0
(1024, 4096)
train.py:12: MatplotlibDeprecationWarning: The 'warn' parameter of use() is deprecated since Matplotlib 3.1 and will be removed in 3.3.  If any parameter follows 'warn', they should be pass as keyword, not positionally.
  matplotlib.use('agg', warn=False, force=True)
Traceback (most recent call last):
  File "train.py", line 70, in <module>
    from apex import amp
  File "/scratch3/venv/proxy/lib/python3.8/site-packages/apex/__init__.py", line 13, in <module>
    from pyramid.session import UnencryptedCookieSessionFactoryConfig
ImportError: cannot import name 'UnencryptedCookieSessionFactoryConfig' from 'pyramid.session' (unknown location)

收到上述错误后，我尝试了这个答案：https ://stackoverflow.com/a/67188946/2414957

  DEPRECATION: A future pip version will change local packages to be built in-place without first copying to a temporary directory. We recommend you use --use-feature=in-tree-build to test your packages with this new behavior before it becomes the default.
   pip 21.3 will remove support for this functionality. You can find discussion regarding this at https://github.com/pypa/pip/issues/7555.

这是来自这个 GitHub repo的代码。

编辑：我通过我现在找不到的stackoverflow答案找到了步骤（上面链接）。我不知道如何找到与 PyTorch 1.9 兼容的正确链接或安装。

仅供参考，git repo 没有安装说明，因此我盲目地安装东西。

标签： pythonpytorchnvidia

解决方案

安装CUDA 11.1然后将以下内容添加到~/.bashrc并获取~/.bashrc最终符号链接使其工作：

export CUDA_HOME=/usr/local/cuda-11.1
export PATH=/usr/local/cuda-11.1/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-11.1/lib64:$LD_LIBRARY_PATH

这消除了卸载 CUDA 10.2 的需要，尤其是在以后需要其他项目时。简单地导出路径而不使用符号链接是行不通的。$ sudo ln -sfT /usr/local/cuda/cuda-11.1/ /usr/local/cuda

^ 最后一个命令假设您的机器上安装了多个 CUDA 版本。有关详细信息，请阅读此 GitHub 问题。
