No module named pdf_diff #34

I tried this tool in several ways like:
python3, 2, anaconda dist python3.
All has some issue or the other.
Even I tried manually cloning the repo and taking the necessary .py files in the corresponding path.
Still I haven't reached a point to manually run a single diff.
Even at some situation only once I reached a point where the command line was working without issues. But that time also when 2 similar formatted pdfs were provided as inputs, the output image that was configured in the cmd line, did not get the output.
I don't know what is the issue with the tool.
Im using windows10 64bit.
Kindly let me know how to resolve this.
Initially I was using pdf2text and it had some consistency and data misplacement issues, due to which I tried using this, but this is my current situation.
Kindly help me on this.
