奇点图像在不同机器上的不同行为？

Question

我试图在远程计算机上运行基于python3的奇点映像，但是我得到了其他机器无法得到的以下错误：

singularity exec --nv --no-home --bind data/:/data/ image/ scripts/train.sh
+ singularity exec --nv --no-home --bind data/:/data/ image/ scripts/train.sh
WARNING: skipping mount of sysfs: no such file or directory
scripts/train.sh: line 8: warning: setlocale: LC_ALL: cannot change locale (en_US.utf8): No such file or directory
Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = '/usr/local/bin/python'
  program name = '/usr/local/bin/python'

  environment = 1
  user site = 1
  import site = 1
  sys._base_executable = '/usr/local/bin/python'
  sys.base_prefix = '/usr/local'
  sys.base_exec_prefix = '/usr/local'
  sys.executable = '/usr/local/bin/python'

  sys.path = [

  ]
Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
LookupError: no codec search functions registered: can't find encoding

Current thread 0x00007f628ee51740 (most recent call first):
<no Python frame>

我的定义文件如下所示：

Bootstrap: docker
From: python:3

%post
    apt-get update  -y
    apt-get install -y git
    pip install torch torchvision
    git clone https://github.com/NVIDIA/apex
    cd apex
    pip install -v --no-cache-dir ./

%runscript
    echo "Running nnunet container..."

如何纠正此错误？为什么图像在我不同的机器上的表现不一样？

这通常是由于环境变量被传递或没有传递到容器而没有注意到。要确保这不是问题，可以使用-e或--cleanenv。这将防止任何未以SINGULARITYENV_为前缀的变量加载到容器中。

这就是说，警告WARNING: skipping mount of sysfs: no such file or directory也有问题:奇点无法将/sys挂载到映像中，因为它不存在于主机服务器上。这个特定的python错误似乎也是特定于windows 10的。奇点目前并不支持windows，即使有了WSL2的魔力。
