【问题描述】：

在本地目录上执行python3（Python 3.6.8）脚本时，效果很好，但是在slurm中运行sbatch作业时，抱怨certifi。

python3 -m pip install certifi

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: certifi in /usr/local/lib/python3.6/site-packages (2020.12.5)

在 python 代码中添加以下内容：

import sys
import os
sys.path.append(os.getcwd())

或者这个：

import sys
import os
module_path = os.path.abspath(os.getcwd())

if module_path not in sys.path:

    sys.path.append(module_path)

同样的错误发生。好像安装了certifi。

pip show certifi

运行python代码后的错误（python代码中没有'import certifi'行）：

    from certifi import where
ModuleNotFoundError: No module named 'certifi'

错误（在python代码中有'import certifi'行）：

Traceback (most recent call last):
  File "/home/username/projecttest_LR_attack/LR_attack.py", line 17, in <module>
    import certifi
ModuleNotFoundError: No module named 'certifi'

有什么办法可以解决这个问题？

【解决方案1】：

计算节点上是否安装了与本地相同的模块？您可能需要咨询 Slurm 管理员。

【讨论】：

谢谢。我得到的建议是创建一个包含所有需要安装的 VM。

【解决方案2】：

这可能意味着 /usr/local/lib/python3.6/site-packages/ 不是 slurm 中的 sbatch 作业可以访问的 PYTHONPATH 环境变量。您可以在运行时添加或附加它：

import sys
sys.path.append('/usr/local/lib/python3.6/site-packages/')

谢谢你的回答，PApostol。但错误仍然是一样的......
