version of dependencies

I think it's necessary to give a list of dependencies version. There are so many changes in the python packages such as scipy and it quite difficult to setup the environment and reproduce the result without the exact version.

Inspect the repository's setup instructions and Python dependency declarations first. Document exact versions for the packages needed to reproduce the environment, including scipy, and verify that the documented versions are sufficient to set up the project consistently.
