<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] Inside of your requirements.txt file, you can use special syntax to define the version requirements for each of the packages. In your case, you could use the following line in your requirements.txt to require a package with a version of 2.0.3 or higher:
```
my_package=>2.0.3
```</s>
