Relative path in Python HAL file

I was trying to use the relative path in python hal file.

CONTEXT:
We have a parent directory called `python` and it contains one python HAL file and one directory named `img`.

The directory tree structure is as follows:
/python
-python_hal
-img

I was trying to reference the img directory in the python hal file by doing either `./img` or `img`, but it doesn't seem to work.
