AttributeError: function 'compare' not found;

Doctor HazenBabcock :
Hello!

After I was runing "python hal-4000.py xml/none_config.xml", these mistakes trouble me a lot. I try my best to fix it but failed. I wonder whether you can help me.
Thanks a lot.

below is the bug.

[HazenBabcock]

Do you have more than one version of storm-control installed on your computer?

This seems to be a problem with the storm-control-master/storm_control/c_libraries/c_image_manipulation.dll library. This library is supposed to have a function called 'compare' but for some reason this function is not found. So one possibility is that an older version of the library from some other version of storm-control is getting loaded instead.

If you add print(c_lib_path) to the loadCLibrary() function in storm-control-master/storm_control/c_libraries, what do you see?

def loadCLibrary(library_filename):

    #
    # c_lib_path is something like:
    #    /usr/lib/python3.5/site-packages/storm_control
    #
    c_lib_path = os.path.dirname(os.path.abspath(storm_control.__file__))

    # All the C libraries are in the c_libraries directory.
    c_lib_path = os.path.join(c_lib_path, "c_libraries")

    print(c_lib_path)

    # Windows.
    if (sys.platform == "win32"):

I did as you said, The output is just shown as "C:\Users\shen\storm-control-master\storm_control\c_libraries" and the others don't change.

AttributeError: function 'compare' not found

My operate system is win7 64bit.
I look up the "c_image_manipulation_c.py"，the “compare” function dose exist in the file.
debug shows module_params.parameters['module_name'] = {NameError}name 'module_params' is not defined .
so what should I do next step for this.

def compare(image1, image2):
"""
This does a bytewise comparison of two images.

image1 - The first image.
image2 - The second image.

Returns the number of differences greater than 1.    
"""
if (image1.size != image2.size):
    print("Images are not the same size!")
    return

return image_manip.compare(image1, image2, image1.size)

[HazenBabcock]

What version of Python and Anaconda are you using?

The problem I think is that the compare function is not found in the C library c_image_manipulation.dll. Did you attempt to compile c_image_manipulation.c yourself? Or are you using the version that is in the storm-control repository?

It's all 64bit.

import sys
sys.platform
#  win32

I find out the problem is that I have the compare function in my c_libraries but I can't use it.
I lack of the operate system knowledge so I can't fully understand the dill file and don't know how to compile it.
And I'll try it.

[HazenBabcock]

Not sure what the issue is as I cannot reproduce it. I did the following on a 64 bit Windows 7 computer.

1. Download and install Anaconda3-5.2.0-Windows-x86_64.exe
2. Download storm-control from github, and extract to c:\users\hazen\storm-control-master
3. Follow the install instructions here for conda.
4. Add a storm_control.pth file to my virtual environment (in Lib\site-packages).

And it all worked as expected.

Thank you sir. I'll keep trying to fix it. If I find where the problem is , I’ll post here.
