@SamSamhuns also in readme under installation section, version of packages are out-dated. Can you please make them correspond the requirements.txt. But to be fair I would rather completely remove such installation option, idk.

Yes, I believe it is better to remove the version numbers in the req. These packages should be backward compatible in updated versions.
