How to make sure that it will install the correct versions of the packages?
user
The requirements.txt file contains the versions of the packages that will be installed. To ensure that pip installs the correct versions of the packages, you should check that the versions listed in the requirements.txt file are the ones you want. You can also specify the version you want to be installed when running the command, like so: pip install <package-name>==<version>.
