in window

i had already added path

C:\Python27\Lib\site-packages\graphviz;C:\Python27\Lib\site-packages\pycallgraph

to environment variable path

but in cmd

'pycallgraph' is not recognized as an internal or external command,
operable program or batch file.

then i use full path

python "C:\Python27\Lib\site-packages\pycallgraph\py

callgraph.py" -- "C:\Users\hello\Downloads\pusher.py"
Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\pycallgraph\pycallgraph.py", line 3, in <m
odule>
from .output import Output
ValueError: Attempted relative import in non-package

This tells you that a required (operating system level) utility
(named "dot") is not available.

Carefully read the installation instructions, especially any
remark about dependencies. This should tell you where "dot" is supposed
to come from. Install all operating system level dependencies.

If "dot" should have come from "graphviz", then maybe a
"hash" is necessary to let your shell see new commands.
