<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] You can specify exact versions of packages in your requirements.txt file by using the == operator. For example, if you wanted to install version 2.0.3 of a package, you would write the following in your requirements.txt file:

package_name==2.0.3

If you wanted to install a version that is at least 2.0.3, you would use the >= operator. For example:

package_name>=2.0.3</s>
