In theory, "pip3" will install into the default "python3", whichever that is. However, in practice, it's entirely possible that it installs into a very different Python from the one you're expecting. The most reliable form is the latter; whatever command you use to start Python, add "-m pip" to it, and you know you're talking to that same installation.
