<s>[INST] This command installs Python packages

pip install -r requirements.txt

How to make sure that it will install the correct versions of the packages? [/INST] The best way to make sure that pip installs the correct versions of the packages is to check the contents of requirements.txt. The command "pip install -r requirements.txt" will install the packages and versions listed in the file, so everything is dependent on that file being correct.</s>\ <s>[INST] Thanks, but how do I make requirements.txt install certain versions for me? How can I make sure that it installs an exact version or a version that is at least > 2.0.3 for instance? [/INST] Sure. Let's say the package name is "package_name", then in the requirements.txt add the line `package_name==2.0.3` to only use version 2.0.3, or `package_name>=2.0.3` to use version 2.0.3 or newer.

I can also give a more helpful answer if you specify what packages need to be what versions.</s>
