Somehow runs on python 2.7 [FIXED]

[himarange]

I ran sh classification.sh -i Sample.csv -d sc command on Mac 11.6
Then errors:

Traceback (most recent call last):
  File "./python/csv_processing.py", line 8, in <module>
    import pathlib
ImportError: No module named pathlib

Followed by more Java errors. I have all requirements downloaded and installed on Python 3.8. Java version 8+.
Then I print sys.path in pySenti4SD/python/csv_processing.py which gives:

/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload

Missing modules are installed on python 3.8 obviously. All requirements were installed in Python 3.8.
Why does my sys.path include python 2.7?

I suspect this has to do with the following file:
classification.sh I think somehow it alters the file path to the old python version....

Any ideas how I can solve this? Or perhaps could the owner of this repository fix this in the directory?

I fixed. In the classification.sh one can change the shell commands.
Changing every python instance to python3 did it.
