import error: no module named tools

Hi, I’m new about blender. And I was to run a script

and have a problem when run. the code are like this:

<script type="text/javascript">
 import os 
import numpy as np
import bpy
from imp import reload
import morph_template as morph
from tools import blender_tools as blender

when I run it blender it comes the ERROR:Import error
: no module named “tools”

(I used blender2.79,
python3.6, Python IDE: Anaoconda it Installed nearly
all the common Python libs)
Would it be probably and
module of blender of different version? If it is what
version of blender of python should it be.If not
which it might be? thanks a lot.
