I guess either you didn't put any module in the target thing,
Or you spelled the module name wrong,
Or you tried to import a module from a different directory which somehow stuffed up.
If the 3rd one is the case, check this out:

py -m pip install # sit module in cmd
import os,sys
sys.path.append(os.getcwd())
#for python3
python3 -m pip install MODULE_NAME
pip install 'modulename'
import sys
sys.path.append('..') #parent directory
sys.path.append('/home/model') # abs path
from folderA.folderB.fileA import functionA
export PYTHONPATH="${PYTHONPATH}:/path/to/your/project/"
pip install <module name>
