Quoted from Gentoo Wiki:

It is important to understand that packages installed using pip will not be tracked by Portage. This is the case for installing any package through means other than the emerge command. Possible conflicts can be created when installing a Python package that is available in the Portage tree, then installing the same package using pip.

Decide which package manager will work best for the use case: either use emerge or pip for Python packages, but not both. Sometimes a certain Python packages will not be available in the Portage tree, in these cases the only option is to use pip. Be wise and make good choices!

This is true for almost any nowadays package managers. If you are using packages or certain package versions that only exists in pip, use it but don't try to install that from dnf. Doing this will not only cause file collisions but also will (most possibly) break the package manager's knowledge of the system, which usually leads to major package management issues.

Other solution would be using pip in user mode, without root permissions, which will install relevant things into your home directory.

So again, it's both okay to use pip or dnf, but just don't mix these two package managers together.

python2-pip isn't available from the Fedora 32 repos as Python 2 is no longer supported. You can install it from the UnitedRPMs repo with the following but I wouldn't recommend it as it's not a supported repo:

rpm --import https://raw.githubusercontent.com/UnitedRPMs/unitedrpms/master/URPMS-GPG-PUBLICKEY-Fedora

yum install https://github.com/UnitedRPMs/unitedrpms/releases/download/17/unitedrpms-$(rpm -E %fedora)-17.fc$(rpm -E %fedora).noarch.rpm -y

The best option is to build it from the source code. You can get it from here: https://github.com/python/cpython/releases/tag/v2.7.18

In regards to your comment below, as a regular user:

pip install amitools==0.1.0 --user

If it is properly installed you can run python3 -m pip to run pip for Python 3.

Installing pip for Python 3 is done with dnf install python3-pip. This should create the script /usr/bin/pip3. Using pip to upgrade pip itself (like it suggests, because the shipped version is older) overwrites the scripts and should not be done.

If you want to use the newest version of pip and and upgrade packages given by the fedora-repo to the ones from PyPI, I recommend using a virtual environment.
