No module named certifi

When executing python3 (Python 3.6.8) script on a local directory, it works well, but when running sbatch job in slurm, complains about 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)

After adding to the python code this:

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

or this:

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

if module_path not in sys.path:

    sys.path.append(module_path)

the same error occurs. It seems that certifi is installed.

pip show certifi

The error after running python code (without having the line ‘import certifi’ in python code):

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

The error (with having the line ‘import certifi’ in python code):

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'

What could be the solution to the issue?

Answer

Are the same modules installed on the compute nodes as locally? You may need to check with the Slurm admins.
