Try to create a sample test.py file, with content:
import os
print('first:')
print( __file__ )
print('second:')
print(os.path.dirname(__file__))
print('third:')
print(os.path.dirname('/some/dir/test.py'))
Run it, python test.py:
first:
test.py
second:
( ... blank ...)
third:
/some/dir
So you can see that the os.path.dirname is not being used properly. It
should not be used on __file__ which returns only plain filename, not the
fullpath.
Try to replace os.path.dirname with os.path.realpath
